How to set boot from a USB flash drive in BIOS. How to load Windows from a USB flash drive in BIOS? Setup Basics

In order to install an operating system on a computer, you need to configure it to boot from a USB flash drive or disk. Therefore, in today's article we will look at how to put a boot from a USB flash drive in BIOS. This must be done in order to begin installing Windows. Since if you just paste bootable USB drive with the system, then nothing will happen. Your old OS will start to boot. If you haven't downloaded the latest version operating system, then read the article - How. Let's now proceed directly to the setup process itself.

After restarting the computer, it is not always necessary to go into the motherboard BIOS for configuration. First, let's try to use Boot Menu(boot menu). To do this, before the system starts to boot, you must press the "F8" key, thus a special window should appear with a list (boot menu) of the connected drives. In this menu, you need to select our USB flash drive with the OS recorded on it.

After that, it should begin, namely copying installation files on HDD... After the computer restarts itself, Windows installation will start with hard disk.

If, for some reason, you cannot open the boot menu, then we will begin to figure out how to install a boot from a USB flash drive in BIOS. But first, I want to briefly tell you what BIOS is.

BIOS (basic input / output system)- a special set of built-in software, which implements the application programming interface necessary for working with computer components and devices connected to it.

To get into BIOS settings you need to have time to press the "Delete" or "F2" button or any other, depending on when the computer boots up. At this point in time, the monitor will display the logo of the motherboard manufacturer or information about the processor, memory and hard drives... In this case, something like this will be written at the bottom of the screen:

  • "Press Del to enter Setup"
  • Press F2 for Settings or similar.

After clicking on one of the buttons, you will need to get into the BIOS settings. Depending on the board, the software of the basic I / O system can be different. I propose to consider the most popular options, as well as configure them to boot from a USB flash drive.

If you have an AMI BIOS installed on your board, then in order to set the order of loading disks, you and I need to perform the following steps:


Note! The USB flash drive must be connected before entering the BIOS, otherwise you will not be able to detect it.


If your motherboard is AWARD or Phoenix BIOS, then to configure Windows boot from a flash drive, we do the following steps:


On many modern laptops, the InsydeH2O BIOS is installed and many are faced with the problem of setting the order of loading disks. Let's deal with this problem together. We will do everything point by point so as not to be mistaken.


Note! If you need to install boot from CD or DVD disc, then in the first place you need to put the item "Internal Optic Disc Drive"

  1. After making the settings, go to the "Exit" menu section and select the "Save and Exit Setup" item, thereby we will save the changes made and exit the BIOS.

Currently, many motherboard manufacturers install UEFI software instead of the usual BIOS, which has graphical interface, as well as support for mouse control and a Russified menu. Thus, it makes it easier for us to solve the problem of how to put a boot from a USB flash drive in BIOS.

If you are lucky, and going into the BIOS you see that the graphical interface has loaded in front of you, then you need to go to additional settings by pressing the "F7" key or the corresponding button in the main window. In the menu that appears, you need to go to the "Download" tab and in the "Order of loading disks" item in the first place put our bootable USB flash drive.

After the changes made, press the "F10" key and select the "Save settings and restart the computer" item.

Let's summarize.

In today's article, we examined how to put a boot from a USB flash drive in BIOS. At the same time, I tried to show in as much detail as possible how this is done in different versions BIOS. As a rule, all settings are reduced to putting the bootable USB flash drive or disk with the system first in the queue. Many users have difficulties with this, since the interface is in English. But as you can see, the developers are doing everything possible to adapt the BIOS for all users. This is clearly seen in the new UEFI software.

The world does not stand still. Once the peak of popularity was to store information on disk or on a floppy disk. Now preference is given to more convenient and spacious flash drives.

To load into BIOS via a USB flash drive, you need to take into account several features:

  • removable disk is recommended to be connected to the connector located with back side system unit. It is he who is on the motherboard;
  • connect the storage device before turning on or restarting the computer.

Regardless of the BIOS manufacturer, to boot Windows from a USB flash drive, you must do the following steps:

  1. Open BIOS. To do this, you need to press Delete or Esc... Service call keys may differ in different versions of the program. They are usually written at the bottom of the screen just before the operating system boots.

Configure boot from flash drive to Bios UEFI

New laptops released no earlier than 2013 have a special BIOS version. One of its features is the presence of protection against installation of operating systems from any media, except for a licensed disk. To install a boot from a USB flash drive in this bios version, you must first disable this protection and set the compatibility mode with other operating systems.

  7. To complete the procedure for creating a bootable USB flash drive, you need to left-click on the "Write" button.

Working through the selection window

After you have created a bootable USB flash drive, connect it to a free port on the system unit and restart. When it starts, you need to methodically press the "F11" key, if nothing happens, then perhaps you have another BIOS version, and you can try using the "F8", "F10" or "F12" keys.

A window should appear to select the download external device, where you need, using the arrows on the keyboard, select the name of the flash drive.

Work throughBIOS

Now I will show you how you can configure the BIOS. Acer laptop Aspire V3-551 to boot from USB stick or CD / DVD drive. There are many pictures ahead, that is, photos.

By the way, don't confuse it with the Acer Aspire 551G. they have different BIOS.

In this laptop BIOS UEFI and configuration are usually more difficult than on regular AWARD / AMI BIOSes.

And so you will see how the autorun of the BIOS is configured on a laptop and how to enable the choice of boot.

Well, let's get started.

First, we need to enter the BIOS.

To do this, press the power button and immediately "click" on the " F2". Why right away? So as not to miss the moment of entering the BIOS.

And so we see the following. Here we can overlook brief characteristics laptop Acer aspire V3-551.

In this tab, enable the ability to call the boot menu using the " F12".

As in the photo shown, we do this, that is, switch from " Disabled" on " Enabled":


We see:


After the switch, a message will fly out, approximately the following content "For the settings to take effect, you will need to restart the laptop."


Click on " Enter", And so we need to restart the laptop while saving the settings, press the" F10" and " Enter".


And we go back to the BIOS. Go to the " Boot"and we see the following:


Hooray! We see all connected devices to the laptop, which can be prioritized for the boot.

For example, I will put a USB flash drive in the first boot, that is, I will boot from a USB flash drive, so that later on to install Windows or boot from a LiveCD, it doesn't matter at all.


As you can see, " USB HDD"this is our flash drive, but" ATAPI CDROM:" - drive unit.

P.S .: The distribution of the priority of loading is set by the keys "F5" - to lower and "F6" - to raise.

There is a little left.

Have you chosen where you will boot from? Have you put it up? And now we save the settings, as usual through the " F10" and " Enter".

And lastly, remember in the paragraph where we enabled the Boot Menu function using the " F12"?

Now you can select the boot priority without going into the BIOS. When turning on, press not the "F2" key, but the "F12" key.

And you will see a window like this:


Here we select the device from which you will boot.

This is, in principle, the whole setting of the boot priority from the BIOS flash drive acer aspire v3-551.
