How to set the BIOS to boot from a disk or USB flash drive? Hot keys on a computer and laptop There is no boot device in the BIOS
Boot order, in translation means the sequence or literally the boot order, if there are a lot of boot options - from a hard drive, flash drive, network, CD / DVD drive, then you need to somehow sort them in order, and set the main one first, this will significantly reduce the turn-on time and booting the computer, because he does not have to go through all the boot options in search of the current one.
How to set Boot order in BIOS
There are several options for settings, menu items can be named differently and located in different places, but there are only two fundamentally different options:
- The Boot order menu lists specific devices that can be ordered in order
- In the Boot order menu, the types of devices are indicated in order, and if there are more than one of them, then there is an additional menu item in which specific devices can already be arranged in order.
The first option is more common and a little easier to set up, you need to find the menu with boot settings, usually it is called Boot or startup, this page displays the boot settings of a computer or laptop, their list depends on the manufacturer, in the example Boot order is simply called Boot but may have a different name, go into it:
We see the Boot Priority Order menu and, on the left, instructions on how to change the order, in general, use the up / down arrows to select the desired item and use the + and - keys to raise it in the list or release it accordingly:
After setting, we exit to the previous menu, in the vast majority of BIOSes, the exit is Esc. The example also contains the Boot Order Lock item - it is needed in order to fix the boot order and it did not change when connecting other devices from which boot is possible, indirectly it also increases the security of your device - an attacker will not be able to connect a bootable USB flash drive and boot from it:
The second option is most often found on old computers, here in the Boot Device Priority the types of devices are lined up according to the list - hard drives, flash drives, network, etc., and in the Hard Disk Drives item, which is not always nearby, you can set the boot priority already from specific devices:
We configure, save the settings, reboot and check that everything works as it should. Below are a few more examples of where to look for the Boot Order setting; on very old computers, this option is found:
We go to the Advanced BIOS Features menu, in the “Boot Order” rectangle - the first, second and, accordingly, the third boot device, from the drop-down menu you need to select the type, if there are several hard drives (flash drives are also often considered a hard drive), then in the very first paragraph - Hard Disk Boot Priority you can specify their priority: 
The "Boot Order" item can be hidden in an unexpected place: 
How to set Boot order in UEFI
The Boot Order setting in UEFI is not much different from that in the BIOS, and is performed according to almost the same algorithm.
We go into the UEFI BIOS, when turned on, a hint is usually displayed at the bottom of the screen on how to do this, for computers in 99% of cases it is F2 or DEL, for laptops there are more options Esc, F1, F2, F10, F11, F12 (sometimes they need to be pressed together with the Fn button) in general, try it. I just can press F2 or DEL:
I press and get into UEFI, the interface for all manufacturers is more or less standardized and built according to the same principle, immediately after entering UEFI you get to an information screen with general data about the computer and indications of the main parameters of temperatures, voltages, etc. Here you can immediately go to the Boot Priority menu and set everything up, but we will go the old fashioned way - we are looking for a way to switch to advanced mode, usually there is either a corresponding button (indicated by an arrow in the picture below), or a key is indicated below with which you can switch to Advanced Mode in our case F7, press: 
Here we select with the up and down arrows or with the mouse - Advanced Mode
And we find ourselves in an extended menu, vaguely reminiscent of BIOS, only richer in graphic terms, then go to the Boot section and then to Hard Drives BBS Priorities:
and set the boot priority by selecting the desired hard drive from the drop-down menu opposite each Boot Option item:
After the Boot Order setup is finished, click on Exit at the top, select Save Changes & Reset to save the settings and restart the computer:
We reboot and check that the download went immediately from the specified device, without wasting time polling the rest.
In general, as you can see, there is no difficulty in setting up Boot Order, and with the help of this article you can easily fix boot problems on your computer or laptop, if something doesn’t work, write in the comments, preferably immediately with a photo, I’ll tell you where to press .
Today I will tell you how to enable booting from a USB flash drive in the BIOS of various manufacturers. It doesn't matter which version you have, the order of gestures will be as follows:
1. We insert our bootable USB flash drive into the USB port of your computer. I recommend inserting it into the port located directly on the motherboard, i.e. from the back of the system unit.
2. Turn on the computer and press the key Delete(or F2) to get into the BIOS. Depending on the manufacturer and BIOS version, other keys (Esc, F1, Tab) may also be used, so you need to carefully read the prompts on the screen.
In BIOS, we can only navigate through the tabs using the keyboard.
Below I will describe this process in detail using the most used BIOS versions as an example.
Attention! Remember that if you are installing the operating system from a USB flash drive or CD and have selected a boot device in the BIOS, and not in the boot menu, then after the first automatic reboot of Windows, you must enter the BIOS again and return to boot from the hard drive. If this is not done, autoload from a USB flash drive or CD will work again, and Windows will again begin the first stage of the procedure. installation.
Configuring Award Bios to boot from a USB flash drive
Award Bios:
First, let's check if the USB controller is enabled. We go to "Integrated Peripherals". We go down with the arrow on the keyboard to the item “USB Controller”. Press the “Enter” key and in the window that appears, select “Enable” (also using “Enter”). Opposite “USB Controller 2.0” should also be “Enable”.
Exit this tab by pressing Esc.
Then we go to "Advanced BIOS Features" - "Hard Disk Boot Priority".Now in my example, the hard drive is in the first place, and the flash drive should be.
We stand on the line with the name of our flash drive (Patriot Memory) and raise it to the very top using the “+” key on the keyboard.
Exit here by pressing "Esc".
Configuring AMI Bios to boot from a USB flash drive
If, upon entering BIOS, you see such a screen, then you have AMI Bios:
First, let's check if the USB controller is enabled. Go to the tab "Advanced" - "USB Configuration".
Opposite the items “USB Function” and “USB 2.0 Controller” should be “Enabled”.
If this is not the case, we stand on this line and press the “Enter” key. From the list that appears, select “Enabled” (also using “Enter”).
Then exit this tab by pressing “Esc”.
Go to tab "Boot" - "Hard Disk Drives".
Now I have a hard drive in the first place, but I need to put a USB flash drive here. We become on the first line, press “Enter” and in the window that appears, select our Patriot Memory flash drive.
It should be like this:
We leave from here through "Esc".
Select "Boot Device Priority". Here, the first boot device must be a USB flash drive.
Press Esc.
Then we exit the BIOS, saving all the settings made. To do this, go to "Exit" - "Exit & Save Changes" - "OK".
Setting up Phoenix-Award Bios to boot from a USB flash drive
If, upon entering BIOS, you see such a screen, then you have Phoenix Award BIOS :
First, let's check if the USB controller is enabled. We go to the “Peripherals” tab - opposite the items “USB Controller” and “USB 2.0 Controller” should be “Enabled”.
Then we go to the “Advanced” tab and opposite “First Boot Device” we set “USB-HDD”.
After that, exit the BIOS, saving the changes. To do this, go to "Exit" - "Save & Exit Setup" - press the key "Y" - "Enter"
That's practically everything you need to know in order to boot from a USB flash drive. In my article, I described the process of setting up the Bios of the most popular versions: Award and AMI. The third example shows Phoenix Award Bios, which is much rarer.
In different versions of the BIOS, the described procedure may be slightly different. But the main thing is that you understand the principle of tuning itself.
By the way, I would also like to add: in order to choose which device to boot your computer from, it is not necessary to change the settings in the BIOS. You can call up a special menu immediately after turning on the computer to select boot devices (this can be done by pressing F8, F10, F11, F12 or Esc). In order not to guess with the keys, we look carefully at the monitor immediately after turning it on. We need to have time to see an inscription like this: “Press Esc to selest boot device”. In my case, it was necessary to press “Esc”.
Most often, we remember the BIOS (Basic Input / Output System) only when we need to reinstall the operating system and need to somehow set it to boot from a disk or flash drive. I often wrote about this in articles such as:, and others. Now I want to gather together and refer only to this article when necessary. This article will be useful for all BIOS versions and for different companies. A sort of single guide
The first thing you need to know is that the BIOS is divided by manufacturer and version.
To change boot method in BIOS- you need to enter it first.
You can, of course, find out what version and manufacturer of your BIOS is from the manual that comes with your computer.
You can also find out by looking at the line at the top on the black screen during boot (the manufacturer will be indicated there).
Well, then enter the BIOS, knowing what it is for you.
In some BIOS versions there is no such screen showing lines. There is just a logo there and something like "Press F2 to enter SETUP" is written below, which means we press F2. If there is just a logo and there are no inscriptions - press ESC, and then del or f2
Here is a small list of manufacturers and keyboard shortcuts for entering BIOS:
Also, at the bottom of the black screen, keys are written to enter the BIOS and to display a list that contains available devices for booting and so that you can boot from it. But about him at the end of the article.
As you can see - most often you need to press the key F2 or Del.
Now you need to put a USB flash drive or disk into the boot.
Let's look at several examples that differ from the BIOS manufacturer.
Configuring Award Bios to boot from a USB flash drive or disk:
The main window is like this, in which we need the second item:
Further depends on the firmware version. In one case, you will need to go to an item similar to "Boot Seq & Floppy Setup"
in another case, you don’t need to go anywhere - everything will be in front of your eyes anyway
clicks on First boot device(First boot device), click Enter and this window will appear
in which you need to select a disk or flash drive that will be launched first. You can specify the Second boot device, for example, but usually the BIOS itself fills in this data.
On a note:
If you choose a flash drive, then, among other things, you also need to go to the “Hard Disk Boot Priority” item and move our flash drive to the very top using the “+” and “-” or “PageUp” and “PageDown” buttons:
It is also worth remembering that in order for the BIOS to see the USB flash drive, you need to connect it before turning it on or before rebooting
Then press "F10" (see the exact key in the prompt at the bottom of the screen with the name "Save", "Exit") or go to the main BIOS menu and select the "Save and Exit Setup" item. In the red box, select "Yes" with the "Y" button on the keyboard and press "Enter"
The computer will restart and when booting from the Windows installation disk, such a request may appear for a few seconds “Press any key to boot from CD or DVD…”
Which translates to "Press any button to boot from CD or DVD."
This means that if at this moment you do not press any button on the keyboard, the computer will continue to boot from the next device in the list.
Another variation of this bios:
I only met this on old computers ten years ago until 2003. The main menu looks like this:
To set the boot order, you need to go to the menu BIOS FEATURES SETUP:
At this point, we just select with the PageUp and PageDown buttons (or Enter and arrows) what to set first - a CDROM or a USB flash drive. DO NOT forget about the second and third device
And further:
How to choose what to boot from in AMI BIOS
If, upon entering BIOS, you see such a screen, then you have AMI BIOS:
Using the right arrow key on the keyboard, move to the Boot tab:
We go to "Hard Disk Drives" and in the line "1st Drive" (may be called "First Drive") select a disk or flash drive:
Next, go to "Boot Device Priority", go to "1st Boot Device" and select from the list what you chose in the previous tab (i.e. if you selected a USB flash drive in Hard Disk Drives, then you need to specify it here. This is important! )
To boot from a CD/DVD disc, you need to select "ATAPI CD-ROM" (or simply "CDROM") in this menu, and there is no need to go to the previous menu "Hard Disk Drives".
Now we save the results with the "F10" button or go to the "Exit" BIOS section and select "Exit Saving Changes".
Another AMI BIOS, but here everything is clear:
Setting up Phoenix-Award Bios to boot from a USB flash drive
If, upon entering BIOS, you see such a screen, then you have a Phoenix-Award BIOS:
Go to the “Advanced” tab and opposite “First Boot Device” set what you need (flash drive or disk):
Save with F10
Configuring EFI (UEFI) Bios with a GUI to boot from a flash drive
Now this is no surprise to anyone. Almost all new computers are supplied with a similar shell. You can read more about it in the article.
When loading, at the bottom of the screen there is a "Boot Priority" section, where you can use the mouse (drag and drop) to set the desired boot order.
You can also click on the "Exit/Advanced mode" button in the upper right corner and select Advanced mode in the window that appears.
Next, go to the "Boot" tab and in the section Boot Option Priorities in the "Boot Option # 1" field, set the USB flash drive, DVD-ROM, hard drive, or other available device as the default boot device.
How to boot from a USB flash drive or from a disk without entering BIOS
This is what I wrote about almost at the very beginning of the article.
This is when you need to press the key once and a window will appear with a choice of download. This method does not change the BIOS settings.
Usually Award BIOS offers to press "F9" to call the boot menu, and AMI asks to press "F8". On laptops, this may be the "F12" key.
In general - look at the bottom line and look for items like "Press F8 for BBS POPUP" or "Press F9 to Select Booting Device after POST".
Why can't I boot from a USB flash drive into the BIOS?
Possible reasons: 
On ancient computers, there is generally no way to boot from USB flash drives. If there is no newer BIOS, then the project can help.
1) Download the latest version of "Plop Boot Manager" from the link above and unpack it.
2) The archive contains files: plpbt.img is an image for a floppy disk, and plpbt.iso is an image for a CD.
3) Write the image to disk and boot from it (or from a floppy disk).
4) A menu will appear in which we select our USB flash drive and boot from it.
Little decoding of disk designations when choosing:
Do not forget after you have done what you wanted (namely, why did you change the boot in the BIOS) - return the boot settings back so that the computer boots from the hard drive.
Good day everyone!
Why memorize something you don't need every day? It is enough to open and read the information when you need it - the main thing is to be able to use it! I usually do this myself, and these keyboard shortcuts are no exception ...
This article is for reference, it contains buttons to enter the BIOS, to call the boot menu (it is also called the Boot Menu). Often they are simply "vital" when reinstalling Windows, when restoring the computer, setting up the BIOS, etc. I hope the information will be relevant and you will find the treasured key to call the desired menu.
Note :
- The information on the page will be updated and expanded from time to time;
- You can see the buttons for entering the BIOS in this article (as well as how to enter the BIOS in general :)):
- At the end of the article, examples and explanations of abbreviations in the table, decoding of functions are given.

REFERENCE (on the above tables)
BIOS Setup (also Enter Setup, BIOS Settings, or simply BIOS)- this is the button to enter the BIOS settings. You need to press it after turning on the computer (laptop), and it is better several times until the screen appears. The name may vary slightly depending on the manufacturer of the equipment.
Boot Menu (also Change Boot Device, Popup Menu)- a very useful menu that allows you to select the device from which the device will boot. Moreover, to select a device, you do not need to enter the BIOS and change the boot queue. That is, for example, you need to install Windows - press the button to enter the Boot Menu, select the installation USB flash drive, and after rebooting, the computer will automatically boot from the hard drive (and no extra BIOS settings).
An example of a Boot Menu is an HP laptop (Boot Option Menu).
D2D Recovery (also Recovery)- Windows recovery function on laptops. Allows you to quickly restore the device from a hidden partition of the hard drive. To be honest, I personally do not like to use this function, because. recovery in laptops is often “crooked”, it works clumsily and it is not always possible to select detailed settings “how and what” ... I prefer installing and restoring Windows from a bootable USB flash drive.
Easy Flash - used to update the BIOS (do not recommend for beginners ...).
System Information - system information about the laptop and its components (for example, this option is available on HP laptops).
PS
For additions on the topic of the article - thanks in advance. Your information (for example, the buttons to enter the BIOS on your laptop model) will be added to the article. All the best!
There are sometimes quite unpleasant situations when the operating system crashes. Restoration requires the original disc. If this is not available, you can write the image to a regular USB flash drive. But here's the problem - what to do when there is no boot from a USB flash drive in the BIOS? Many users simply do not know what to do, and are lost in this matter. Let's try to dot all the i's.
How to enable in BIOS the simplest method?
To set these parameters, you must first decide how exactly you will enter the BIOS. The most common way is to use the keys Del, F2, F12, etc.
However, on the same Sony Vaio laptops, access is carried out using a special ASSIST button placed on the keyboard panel. On some laptops, access to the BIOS can only be obtained by calling the primary boot menu using the Esc key.
How do I set the BIOS to boot from a flash drive? Yes, very simple. After calling the I / O system, you need to go to the boot section (Boot). Here you need to find the boot priority line, which may have different names, depending on the developer and manufacturer of the BIOS (Boot Device Priority, Boot Sequence, etc.). In any case, something like this will be present. But that's not the point.
What to do if there is no boot from a USB flash drive in the BIOS?
It also happens that the bootable USB flash drive is not recognized by the primary I / O system. With what it can be connected? There are usually several reasons for this:
- incorrectly written image or installation distribution;
- damage to the USB stick itself.
To make sure that all the steps for booting from a USB flash drive are completed correctly, you need to take a few steps. For now, let's leave the question of how to enable booting from a USB flash drive in BIOS in the background, and move on to pressing problems.
Checking in Device Manager
Let's start with the last point. When checking the device itself for its functionality, there can be two options: either it is faulty in itself, or the accompanying driver is missing or incorrectly installed, which is responsible for recognizing the flash drive by the operating system.
In case of malfunctions, everything is clear. The device will simply have to be replaced. But what to do when it is in working condition (at least it is detected on another computer or laptop)? You need to check its functionality. And for this, in the simplest version, you just need to insert it into the appropriate USB 2.0 / 3.0 port, and then call the standard “Device Manager” through the “Control Panel” or use the devmgmt command in the “Run” menu bar (Win + R).
Suppose that after inserting it into the port, it may either not be displayed in the manager, or it may be displayed with a yellow icon, on which it is present. In the second case, everything is simple: you need to install or reinstall the driver. It may very well be that the system itself does not find a suitable driver, although it should do it automatically. But this mostly applies to non-standard devices. Flash drives like Transcend are usually recognized immediately.
If the device is not displayed in the corresponding manager, there may also be two reasons: either the appropriate driver for the universal USB controller is not installed, or the port itself is faulty. Again, you should install the driver (the controller is indicated in yellow or not in the manager at all), or try plugging the USB flash drive into another port. It should be noted that if the device is designed exclusively for data transfer with only USB 3.0 support, it will not be detected when connected to a standard 2.0 port.
Formatting Partitions on a USB Device
Let's leave aside the question of how to boot from a USB flash drive in BIOS for now, and move on to the procedures, without which even writing an image to install the system on a device may be in vain.
First of all, if the device has problems in operation or nothing can be done with it, you should first format it. In this case, it is undesirable to do a quick cleaning of the table of contents, but it is better to do a full formatting. Only in this case, the file system contained on it will ensure the correct transfer of data and their reading.
Such an operation is performed in the standard "Explorer". On the device, you just need to right-click, and select the appropriate line from the menu. In a new window, be sure to uncheck the quick format line, and then activate the start of the process. Depending on the total volume, this may take a long time.
Creating a bootable distribution
If we consider the question of how to set boot from a USB flash drive in BIOS even more broadly, we cannot ignore the issue of creating a boot image and transferring it to a drive. This can be done using the UltraISO utility or the like.
However, the original Windows installation disc must be used as the source. Actually, it is not so difficult, so there is no point in dwelling on this in detail. And if there is no boot from a USB flash drive in the BIOS, in the future it all comes down to correctly transferring the image or unpacked distribution files to the drive. Here you have to tinker a little.
Media preparation
If you use the system's own tools, even after formatting with a USB device, you need to perform a number of additional actions (it is assumed that the image has already been created from the original disk using the same UltraISO program or even 7-Zip, and the flash drive is in working order and connected to a computer or laptop).
First, we call the command line (cmd in the Run menu), always on behalf of the system administrator. In the console that appears, enter and press the enter button.
After that, we use the list disk command, again, followed by pressing the Enter key, after which we look at the available disks and remember the number of the USB device. To accurately check the USB drive number, you can use the diskmgmt.msc command from the Run menu.
Now in the console you need to enter the select disk command and specify the number of the disk you are looking for, separated by a space. Next, the device should be cleared of the contents with the clean command.
The next step is to create a primary boot partition. This is done using the create partition primary command followed by input. After confirmation of a successful operation appears on the screen, use the select partition 1 command, then - active (to activate the selected partition) and finally - format fs = ntfs quick for formatting with a choice If you want to create a FAT32 file system, use the similar command format fs =fat32 quick.
The next step is to assign a name to the device using the assign command (the name will be assigned automatically). Finally, we enter exit and exit. The bootable USB device is ready to go. It remains only to correctly transfer the distribution files to it.
Transferring data to a flash drive
At this stage, configuration is no longer required. We don’t need BIOS to boot from a USB flash drive yet, but we need the 7-Zip program. In the simplest version, it can be used to correctly copy the installation files to the media (roughly speaking, extract them from the image).
We launch the Zip File Manager utility from the standard "Explorer", then select the image of the installation distribution kit that was previously created or downloaded from the Internet, specify the USB flash drive as the final device and confirm the actions by pressing the OK button. At the end of the process, the media will be completely ready for use.
Start download
And now let's move on to the question of how to install boot from a USB flash drive in BIOS directly. We reboot the system and at the initial stage we press a key or a key combination to enter the BIOS settings. Usually this is Del, F2, F12 (for ASUS laptops, BIOS loading from a USB flash drive is done exactly like this), but other keys or combinations described above can also be used. Depending on the manufacturer of the equipment, you may first need to call up the main menu. This situation is typical for laptops like HP - booting from a USB flash drive (BIOS) is set up a little differently, although the operations themselves are very similar.
In the boot section (Boot) look for the item Boot Device Priority and look at the line 1-st Boot Device. By pressing the PgDn key, select the desired device, after which we exit with saving the parameters (as a rule, this is done using the F10 key). This is followed by a reboot, and the installation starts automatically.
However, it is not enough to know how to choose to boot from a USB flash drive in BIOS. It is important to remember that you should only call up the settings of the primary I / O system when a USB device is connected before the computer or laptop starts to boot. Otherwise, the flash drive simply will not be detected.
How to fix problems?
Now let's look at a situation where the device seems to be working, since all the above steps are supposedly performed correctly, but in fact there is still no boot from a USB flash drive in the BIOS. How to proceed in this case?
We use the same command line. Let's assume that the USB device in the system is denoted by the letter F, and the optical drive is E. Now you need to write the command E: \ Boot \ bootsect.exe / nt60 F: (F is a flash drive in our case, and E is a drive).
Alternative Method
If that doesn't work, enter the following one by one:
F:\Boot\bootsect.exe /nt60 F:
After that, everything will definitely work as expected.
Compatibility Issues
If none of the above methods helps, you should first pay attention to the status of the drivers. In the best case, you can use programs like Driver Booster, which are able to update drivers automatically.
If they are OK, the reason may be that the user is trying to install a 32-bit system over a 64-bit one. In addition, the file system on a USB drive and the installation distribution may also differ in bit depth. Actually, the flash drive itself may not support the USB 3.0 ports into which it is included. Here you need to be very careful.
Instead of total
That, in fact, is all that concerns how to set the boot from a USB flash drive in the BIOS. Of course, many users may have questions about the advisability of using the system's own tools for preliminary actions, because automated programs make this much faster and easier. But here I would like to note that such knowledge is extremely important, and programs in case of failures in access to the Internet are also not always at hand.
But a prerequisite, as is already clear, is a disk image that is created based on the original or downloaded from the Internet. Without it, nowhere. It remains to add that attention should also be focused on the bitness of the installed system, since the 32-bit version will not be installed over the 64-bit one without formatting the system partition. This is due only to the fact that for OS versions of 32 bits, and for 64-bit modifications, a minimum of NTFS is required. And on the flash drive itself, the corresponding FAT or NTFS file systems must be present, and not UDP, as is sometimes the case. As for the volume, 4 GB will be quite enough for any system, including even the tenth modification, which is gaining popularity.
