To install almost any operating system from the outset, it is imperative to configure the input / output system (BIOS) of the computer in order to change the boot priority. WITH optical media information, you will install the operating system, that is, from (CD / DVD) or from a flash drive, you must correctly set BIOS settings, believe me it's not difficult. So, in order for the BIOS to boot from a disk, you will have to change the BIOS settings yourself, so that when the computer is turned on, an attempt is made to boot from a CD or from a flash drive, and then from hard disk... If you don't find something in this article, try looking elsewhere.- differs from booting from a floppy drive on a desktop computer.

When you turn on the computer, the first thing to do is to test the equipment for operability, in simple words it kind of checks itself, this is the so-called procedure (POST), then the baton is passed to a special program (MBR), which chooses from which partition on the hard disk to boot operating system, so before this choice, we must boot from a CD or from a flash drive, as in our article.

The computer should reboot and if you have an operating disc in your CD-DVD drive Windows system XP or Windows 7, the OS installation should begin.
In order to reinstall Windows on a computer, you need to boot device select not a hard drive, as usual, but a CD-drive, which contains a disc with installation files operating system. To do this, you need to configure the BIOS so that the data from the CD is read before loading other devices.
Installing boot from disk is complicated by the fact that there are several flavors of BIOS, which differ in the way they are configured. The most common brands you can see on computers are: Award Bios, AMI BIOS and Phoenix-Award Bios.

Hello, I wanted to write detailed instructions on installing Windows, as I remembered that some may have difficulties to install boot from disk... Therefore, in this article I will tell you how to put boot from disk in BIOS.
Exists different kinds BIOS and some of them are first puzzling over where to put the boot from the disk. Now I will try to show you, and after this article, I think you yourself can put boot from disk in any bios.
BIOS types
How to put boot from disk in BIOS?
The main types are Award BIOS and on the I'll show them based on how to set boot in BIOS from CD-ROM to boot Windows from cd or dvd disk. I also recently supplemented the article, so it is possible that your bios will be.
Award BIOS
Here we choose Advanced BIOS Features
This is where we set the load from CD-ROM, then we save ( F10 yes).
AMI BIOS (American Megatrends, Inc.)
Selecting a tab BOOT.
Push Boot Device Priority and Enter.
We choose CDROM... Later save (F10).
What other types of cr-rom installation are there?
Also, in addition to the selection on Enter, there are other selection keys, for example, the following:
If you do not know English, let me explain what is written on the right: Press the Up or Down arrow to select a device, then press F6 to move the device up the list, or F5 to move equipment down the list. Click on ESC to exit to the menu.
Therefore, use the arrows to select CD-ROM and then press F6 until the CD-ROM drive is at the very top. Sometimes the choice is the plus keys (+) and minus (-)... And sometimes a list of active and inactive devices appears. In which pressing the key R you put the CD-ROM active in order to put the boot from the disk. After all installations save (F10 + enter).
Modern bios
In a modern bios, everything is simpler. There are several options to choose from. The first of them, when the BIOS is loaded, you can simply drag the disk to the first place with the mouse and save the changes by pressing F10. But if you do not have such a function, then go to Advanced Mode or if there is a boot.
In advanced settings, go to the boot tab and go down until you see the device boot lines. We go to point number 1 enter.
Download options will appear. Select dvd-rom and save F10.
Also, if you have a password for bios, you can reset it by removing the battery on the motherboard for 10 minutes. If it does not help, you can use it. You can also try before loading windows call the boot dialog of the initial device. For this, before booting Windows you need to press the boot key of the device, they may all be different F1 to F12, and can also be a key Enter.
Do not be afraid to do something superfluous, you can always leave without being saved, and from experiments, your experience and knowledge only increase =)
I think after studying the article to put boot from CD-ROM will not be difficult, what do you think?
Before I start talking about how to put boot from a disk on a laptop or computer in BIOS, let's see a list of tasks in which this operation can be useful to you. Here they are: when installing Windows, working with hard drives, testing computer components, reset Windows password and many other operations faced by every user personal computer... As you understand, everyone needs to know this and therefore you should deal with this issue.
The reason for writing this article was your letters, which I always read and try to respond as quickly as possible to the questions asked. After a series of publications devoted to the question of how to install Windows started receive emails related to changes in the BIOS. Let me remind you that changing the boot priorities in the BIOS is an integral part of reinstalling / installing Windows.
Here is a list of articles for Windows installations:
What is BIOS
To make it clear what we are going to do now, you need to understand the theory a little. The term BIOS means special program responsible for the correct and consistent operation of devices and components installed or connected to the motherboard. Such programs occupy space between the hardware nodes of the computer (Hardware) and software(Software). In the IT field, a class of such programs is called Firmware.
The BIOS is responsible for several very important functions that ensure the health of the computer as a whole.
Firstly is the granting of access by the operating system to the hardware devices installed on the computer. It is the BIOS that allows Windows to interact with hard disk, video card, keyboard and other components.
Secondly, each start-up of the computer begins with testing the connected devices. This is the so-called POST procedure. It is during its implementation, when a malfunction is detected, the computer can give various sounds. More details about them can be found in the article: "".Thirdly, BIOS determines the order in which the operating system boots. That is, thanks to the settings (which will be discussed below), it is automatically determined from which device and in what sequence to receive information.
Fourth, BIOS performs whole line service functions. They are of secondary importance and are of more interest to service engineers.
If you are wondering why you need another BIOS, then you can go into it and see what settings are contained in it. This will help you understand what else you can do with BIOS... For example, you can set the settings in the BIOS so that the computer turns on without a keyboard.
As you can see, the BIOS is a very important component. It allows you to flexibly configure the system (in modern versions, there are more than 130 customizable parameters). But we will only be interested in one - the loading order. Let me explain why. BIOS is not a program to experiment with. In relation to her, the principle: if you do not know, do not do it, it is absolutely fair. Because setting the settings incorrectly, the computer may not turn on! In this case, you can reset the settings to factory defaults, so keep in mind.
A small nuance. In the comments and letters, the question is often asked: I entered the BIOS and it is not the same as in the screenshots, what should I do? There are several manufacturers who are working on creating similar programs. The most famous of these are Award Software (AwardBIOS), American Megatrends Inc (AMI BIOS) and Phoenix Technologies. In fact, these manufacturers hold 95% of the market. Therefore, if you do not have the first option, then most likely the second or third. They differ only in appearance. In fact, the structure of the BIOS is rigidly standardized. Therefore, if the picture on your monitor differs from the screenshot, follow the labels and sections. Their meaning is the same.
As I mentioned above, the main interest for us is the ability to change the boot order of the computer. Let us consider it in more detail.
How to change boot priorities in BIOS
In order to make any changes to the BIOS, you first need to go into it. This is very easy to do. Immediately after turning on the computer, an inscription of the form will appear at the bottom of the screen Press DEL to enter SETUP or as an option Press ESC to Enter SETUP... Press this key and enter BIOS. Options F1, F11, F12 are also possible, but they are relatively rare. The buttons that serve to enter the BIOS appear on the screen for a few seconds if you enter the BIOS for the first time and did not see desired key to enter, then restart your computer to see this inscription.
Note: navigation through the Bios sections is carried out using the arrow keys, the Enter key (enter the section) Esc (exit the section). Several times I saw BIOS when it was possible to control the mouse and touchpad (laptop), like this BIOS is installed on HP.
After we entered the BIOS interface, we will be interested in the Advanced BIOS Features section. It can also be called simply Advanced.
So, we have found the necessary section, where the priorities change, now it remains to find out how to put the boot from the disk in the BIOS. Now find the Boot, Boot Priority or Boot Sequence sections. This is how it looks in AwardBIOS:
Maybe like this:
Here's another example: 
When you have found and entered the section where priorities change, you should find the inscriptions:
FirstBootDevice or 1st Boot Device, select this option and press Enter. They are responsible for the order in which information is read. When the computer starts up, the system first accesses the first device. If it does not contain boot data, then the transition to the second device occurs. Etc.
A menu will open in which you have to select CD / DVD or any other device, for example, a USB flash drive. To select the desired parameter, press the up and down arrows, select CDROM by pressing the button Enter... If in FirstBootDevice or 1st Boot Device you have the CD / DVD option set, then you did everything right.
If you need to install Windows, then now you need to insert your installation disc with Windows. After making changes in the BIOS, you need to save them. This is done using the Save & Exit Setup menu item or the F10 button.
If you do not want to save the changes, just select the Exit without saving item. And one more little secret. If the spirit of the experimenter still forced you to change unfamiliar parameters, then for such a case there is Load default settings, which will restore all the default values.
After installing Windows, you will need to change this setting again to boot from a hard disk drive (HDD). You don't need to do this, but if you are an inexperienced user and forget about the information that I presented in this article, then a problem may happen when you forget some boot disk in your drive and it will automatically boot. Thus, you will not be able to log into Windows. The choice of a hard disk is done in exactly the same way as with a CD / DVD, only you need to select HDD or Hard Disk.
Boot quickly from the device you want
There are also very useful function, with the help of which you can not enter the BIOS, do not make changes in it. The essence of this function: when you turn on the computer, you usually need to press F11 or F12, after which a window appears in which you select desired device... In our case, this is a CD / DVD.
In this window, you move with arrows and when you have highlighted the desired drive, press Enter. Then the boot from the disk will start. If you cannot do this, then use the information that is outlined in this article, or you need to go into the BIOS and find how to enable this function on your computer or laptop.
As you can see, changing the boot priorities in the BIOS is very easy. The main thing is to do everything calmly and slowly. If you didn’t find desired section, then you will need to go to each section to find a choice of boot priority.
And that's all for today.
There are many types of BIOS: Ami, Award, Phoenix Award, UEFI. Let's figure out which buttons to press when booting a computer or laptop in order to go to BIOS and put a boot from a USB flash drive to install windows. I want to note that the traditional key delete, F2 to enter the BIOS. Below are combinations of buttons on how to enter BIOS in order to boot from a USB flash drive.
Buttons for entering bios from laptop and computer manufacturers.

How to put a boot from a USB flash drive in BIOS for installing Windows
To begin with, you don't always need to go into BIOS to swap the bootloader for installing windows. For this there is the so-called launch menu... To go there, you need to turn on the computer, sometimes a key is written. In this case, F12. Press the key that is written in the word Boot Menu.
How will we start the computer: USB flash drive or other devices. The next step is to install the windows system.
How to install a boot from a USB flash drive in Ami Bios
- Push Device Priority.
In line 1st devise we set the priority from the flash drive. This is usually all, but many have come across why I did everything right, and the computer does not start from a flash drive. It is just necessary to specify sometimes, in addition to priority, forced loading in the line Hard Disk Drives.
- V Hard Disk Drives we set a forced start from a flash drive.
- V 1st drive choose the carrier.
- Press F10 to save.
It turned out that in the 1st Devise and Hard Disk Drives settings there is a bootloader with USB Flash those. we put the priority option, tried it and it didn’t work. Then we set a forced launch and everything worked out for us. And so in all versions of the BIOS, if the priority loading did not work.
