Boot menu bios how to open. How to enter the Boot menu - boot menu. How to enter the boot menu on a laptop and computer
Do you want to know how to enter the special boot BOOT menu of a computer or laptop?
To boot from a flash drive or CD - DVD disc A?
In this article you will learn how to do it correctly.
When we do clean install Windows, then we need to boot not from the hard drive but from another medium.
This is either a CD - DVD disc or a flash drive.
Typically, this is done by entering the BIOS of a computer or laptop.
This is exactly what we did in previous lessons.
We went into the BIOS and changed the boot order of the devices.
It is at this step that approximately 90% of users who want to reinstall Windows stop.
They cannot enter the BIOS and make the necessary settings there.
Exists alternative way select boot device.
This is the BOOT menu. The BOOT menu is simpler and more convenient than entering the BIOS.
The essence of the BOOTH menu is to press a certain key when booting a computer or laptop.
A menu like this appears:
In this menu we can select any device and immediately boot from it.
Let's look at this in more detail.
I connected it to my laptop bootable USB flash drive. On my laptop, the Escape key is responsible for entering the Boot menu.
I pressed the Escape button, hold it down and, at the same time, turn on the laptop with the button. The Boot menu opened in front of me.
Cursor keys, up down, I select required device. In this case it is a flash drive.
Once the desired device is selected, press the Enter key.
Ready! I booted from the flash drive and now I can start Windows installation.
So, to enter the BOOT menu, you need to press one key when you boot your computer or laptop.
As with the BIOS, the BOOT menu keys differ depending on the manufacturer and brand of your laptop or computer.
The most common keys are:
F12, Esc, F11, F9 and F8
Boot menu has significant advantages over BIOS.
1. Boot menu is simpler and faster to use.
2. You don't need to understand and change complex BIOS settings. Let me remind you that there are settings in the BIOS that, if you change them, your computer or laptop will stop booting completely. Using the Boot menu you will avoid this.
3. There is no need to return the BIOS settings back to their original state.
Of course, the Boot menu also has its own characteristics.
If you have Windows 10 or Windows 8.1, then to enter the BOOT menu, I recommend using restarting the computer instead of shutting down. The fact is that in these operating systems, the so-called Quick Start is activated by default.
Fast startup makes sure that when you shut down the computer does not turn off, in the usual sense of the word. He falls asleep, or rather enters hibernation.
So when you enable it, it will not give you the option to enter the Boot menu. It will simply wake up and show you the state it was in when you clicked the shutdown button.
The solution is very simple: use a reboot instead of shutting down.
Let's see how it's done:
So, my laptop is turned on, Windows is loaded, the bootable flash drive is connected. Now I enable reboot.
![](https://i2.wp.com/gps-pc.ru/i/pc/kak-zajti-v-boot-menu-na-noutbuke-i-kompyutere/but-menyu.jpg)
I just click on the Start button, click the Shut down button and click Restart.
Once the BOOT menu is in front of us, we can start installing Windows.
Quick startup can be disabled completely. And then you can use the Boot menu as usual when you turn on the computer.
![](https://i0.wp.com/gps-pc.ru/i/pc/kak-zajti-v-boot-menu-na-noutbuke-i-kompyutere/boot-menu-asus.jpg)
The setup is very simple, I will now show you how it is done. Quick Start is disabled via the classic Control Panel. On Windows you can open it via search. Just enter the word “panel” into the search. As soon as the Control Panel icon appears in the search results, I simply press the Enter key.
![](https://i2.wp.com/gps-pc.ru/i/pc/kak-zajti-v-boot-menu-na-noutbuke-i-kompyutere/boot-menu-na-noutbuke.jpg)
In Control Panel, you can switch from categories to icons. Or you can simply search for Power Supply.
On the left we have Power Supplies. Click on it.
![](https://i2.wp.com/gps-pc.ru/i/pc/kak-zajti-v-boot-menu-na-noutbuke-i-kompyutere/boot-menu-lenovo.png)
Here we need a button Actions of the power buttons. Click on it. To unlock settings that are not active, you need to click as shown in the picture. Changing parameters that are currently unavailable.
![](https://i2.wp.com/gps-pc.ru/i/pc/kak-zajti-v-boot-menu-na-noutbuke-i-kompyutere/kak-zajti-v-boot-menu.png)
Now we can disable Quick Launch (Fast Boot), just uncheck the box. Then we save the changes.
After this, the Boot menu will be available to you upon boot.
In Windows 8.1, the setup is done in a similar way.
One more feature.
In some sophisticated BIOS and not so sophisticated ones, there is a menu item that disables the BOOT menu.
More details about this in the video.
If your BIOS has such an item, then you will have to go into the BIOS and enable the BOOT menu once. That is, activate this item.
After this, the BOOT menu will be available to you upon boot.
From the table, you can find out which keys you need to press on your PC or laptop to enter the BOOT menu.

When installing operating system You must go to the Boot Menu to tell your computer which device to boot from. This is also necessary when you need to start from a Live CD or bootable USB flash drive. Today I will tell and show you how to enter Boot Menu How on motherboards PCs and laptops.
Just like you need to press a special key (F2 or Del) to enter the BIOS or UEFI, there is also a specific button to bring up the boot menu. As a rule, these are the F11, F12 or Esc keys, but there are exceptions. Usually, when you turn on the computer, under the splash screen you can see a key that is responsible for calling the Boot Menu.
You can, of course, do without the Boot Menu by simply selecting a certain order for loading devices in the BIOS, but if you want to boot one-time (checking for viruses or installing a system), then I would advise using the boot menu, because it is much faster.
So, why do you need the Boot Menu at all - you ask. This menu shows a list of devices connected to the PC from which you can boot (flash drives, CDs, hard drives) for further installation of the system or for testing components.
Logging into the Boot Menu in Windows 8 and Windows 10
If you are the proud owner of a laptop on which Windows 8, 8.1 or Windows 10 was originally installed, then you may not be able to enter the Boot Menu. I’ll explain why: shutdown in these systems is not complete, since it is more like hibernation, so when you press F11, F12, Esc, the boot menu may not open. There are several ways to fix this:- hold down the Shift button when selecting “Shutdown” and then the PC should turn off completely;
- disabling quick system startup - in G8, go to the Control Panel,
Go to "Power Supplies"
On the left, click on "Power button actions"
Disable the “Enable” item quick start"(you can do this not even on a laptop).
Logging into the Boot Menu on Asus laptops and motherboards
Almost all landlines Asus computers To enter the boot menu you need to press the F8 button immediately when the computer turns on. If we press F9 or Del, we will get to the BIOS.Regarding laptops, it's a little confusing. The Esc key opens the boot menu on modern models; on older laptops, the F8 key works, and mainly on models whose names begin with the letter k or x. In short, if the Esc key does not bring up the Boot Menu, then we reboot and try pressing F8.
Logging into the Boot Menu on Lenovo laptops
To call up the boot menu on Lenovo laptops Just press the F12 key. If you want to use additional options loading, press the additional arrow key,Logging into the Boot Menu on Acer laptops
On all Acer laptops and all-in-one PCs, the Boot Menu can be accessed using the F12 key when turned on. But laptops from this company have one unpleasant feature - the ability to call the boot menu is disabled in the BIOS settings. To fix this, let's get into the BIOS by pressing the F2 key. Now let's find the "F12 Boot Menu" parameter and activate it so that the word Enabled appears next to it. All that remains is to save the settings and exit the BIOS.Below in the table you can see all other laptops and the key to call the Boot Menu and BIOS:
I hope the information in this manual was useful to you. If you have any difficulties getting into the boot menu, then write in the comments, I will try to help!
Good day everyone.
When installing Windows (for example), it is very often necessary to select boot media other than hard drive. This can be done in two ways:
1) Go into the BIOS and change the boot queue (i.e. put the flash drive in the boot queue before the HDD - this way the PC will first check the flash drive for boot entries, and only then HDD);
2) Call the Boot Menu and select the specific media to boot into this moment. In my opinion, this option is even better than the first: faster and no need to go back and forth into the BIOS to change the boot queue.
To enter the BIOS (call Boot Menu) in most cases the following keys are used: F2, Del, Esc, F12 (depending on the device manufacturer). The button must be pressed immediately after turning on the computer (you can do it several times so as not to miss the right moment.
By the way, if you look closely at the first screen, which is visible immediately after turning on the computer, there is often a button written on it to enter the necessary settings (call up the menu). An example in the screenshot below.

Table No. 3: recovery from a hidden partition (for laptops)
Most modern laptops have a built-in hidden section with the ability to restore Windows OS using a “pair” of keys (no need to prepare a bootable USB flash drive, download ISO images with Windows, etc.).
As a rule, to launch the recovery function, after turning on the laptop, just press one key (F9, for example, on Asus laptops). Next, a window will appear in which you need to follow the instructions of the recovery wizard.
Note: when restoring information, the system drive “C:\” is often formatted and all information is deleted from it. Make a copy of important data from it in advance.

So, you need to boot from a flash drive or other device, for example, to install an operating system or scan the system for viruses. To resolve this issue, there are two options. For the first method, you first need to enter the BIOS, then go to the boot menu, and there set the device from which you want to boot the computer. The second method does not require entering the BIOS, you just need to call the boot menu directly, this is done by pressing keys when starting the computer.
Keys to enter BIOS and Boot Menu
Typically, the keys for entering the BIOS and Boot Menu (POST keys) are indicated at the initial stage of booting the computer; in the screenshot, these keys are indicated at the bottom of the screen.
In our case, to get to the boot menu you need to press the key, and to get to the BIOS you need to press the key.

After pressing the keys, the BIOS system menu will open. The appearance of the BIOS system may differ depending on the motherboard manufacturer and BIOS version.
But every version of Bios has a Boot menu, and this is exactly the parameter we need to find – Boot if we need to set it to boot from a flash drive, for example. Next, let's look at entering the boot menu without visiting BIOS.
Keys for calling up the boot menu on laptops and personal computers
At the beginning of the computer boot, you can see a key combination or key (POST hotkeys) by pressing which you will be taken to the boot menu directly bypassing visiting the BIOS. On some computers, Boot Menu hotkeys may be disabled by default in the BIOS. To be able to use hotkeys, you need to enable it in the BIOS settings. Opposite the F12 Boot Menu column you need to set the Enabled parameter.
This must be done before loading the operating system. If this does not work, restart the computer and try again.
This is what the boot menu looks like; the appearance may vary depending on the manufacturer. Listed below are the keys (POST keys) for calling the boot menu for laptops and personal computers.

So, if you need to change the boot order of devices, for example, set the computer to boot from a flash drive, in this case it is not necessary to go into Bios, it is more convenient to use the POST keys and call the boot menu directly. Successful work!
Sometimes it becomes necessary to boot a computer (or laptop - there is no difference) bypassing the installed operating system, from external media: CD/DVD disks or flash drives. These can be so-called LiveCD or other utilities for recovery, testing and other needs.
1. Insert the flash drive into the USB connector or install the disk into the drive. In the case of a disk drive, you can only open it while the computer is running (we won’t talk about the method using a needle or pin).
2. Turn on the computer. A window appears with a splash screen (usually the motherboard logo) and at the bottom of the screen, as a rule, it will be written which key you need to press on the keyboard to download Bios And get to the Boot Menu. You need to have time to press the desired key before the operating system starts loading. Otherwise, you will have to restart your computer and try again.
Advice: Press the desired key repeatedly as soon as the monitor screen lights up when you turn it on.
If you need to perform a one-time boot operation from external media, you can use the quick Boot Menu (the settings will not be remembered). If you plan to boot from disks and flash drives regularly, you can Bios setup. I don’t recommend doing this to boot from flash drives, because then when you start the system, every time you start, it will first try to boot from the flash drives (if you forgot to remove them), and only then access your hard drive. This will take additional time when turning on the computer and loading the operating system. This was a lyrical digression, let's return to practical actions.
In most cases, on motherboards from different manufacturers, the start buttons Bios And Boot Menu different.
3.1. For launch Boot Menu Usually one of the keys on the top row of the keyboard is used. Most often: Esc, F1, F2, F7, F11, F12 .
The Boot Menu looks something like this:
The list shows all the media from which you can try to boot: disk drives, hard disks, flash drives (in this case HL-DT-STDVDRAM GT40N- this is a disk drive and WDC WD5000BPVT-60HXZT3 - hard drive, if you insert a flash drive, then it will appear in this list). Using the arrows on the keyboard, select the desired media and press Enter. The download will begin from the specified media, but our choice will not be remembered. If you need to download again, the operation will have to be repeated.
3.2. If for some reason you were unable to boot from a disk or flash drive using the description from paragraph 3.1., then proceed to Bios settings.
The most common keys used for Bios downloads also the keys of the top row of the keyboard: Del, F2, Esc, F10, F12 .
We get to Bios. The figure shows one of its options appearance. The interface on different motherboards may differ, but the essence of the required settings remains the same.
Finding the section Boot(or Boot Menu). Go to it by pressing the arrow keys - left-right - and press Enter, to expand the section.
Select with arrows Boot Option #1(may be called First Boot Priority or similar) and press Enter. A selection window opens. Here we indicate which device we want to boot from first. Select and click Enter .
Similarly, you can assign a device from which we will boot in the second place, etc.
If you don’t find yours in the list of devices (for example, if you are going to boot from a flash drive, and the computer decides that it is another hard drive). Then you should go to the section Hard Drive Priorities. All hard drives will be listed there, and you can set the boot order for them in the same way.
When all the necessary changes have been made, click F10 (which actually calls the command Save and Exit - Save and Exit) and confirm saving the settings by selecting Yes(sometimes you need to enter a letter y from the keyboard).
That's all. Good luck!
