1. Boot from USB using the Boot Menu (F4, F8, F10, F11, etc.)

One of the easiest ways to boot your computer from a USB drive is by using the boot menu. This works on almost any PC, no matter what operating system is installed. Make sure that your USB flash drive is bootable, and then plug it into any USB port on your laptop or desktop computer. Plug your bootable drive into a USB port Then, turn on your computer (or restart it) and immediately press the key that opens the Boot Menu. It’s usually F4, F8, F10, F11, or F12, but some systems might use Esc or Del instead. If your computer displays a message like “Boot from UEFI USB” or “Press F12 to select boot device” during startup, that’s the key you want to press. If nothing shows up, try all the keys I mentioned. And if none of them work, check your laptop’s manual or your motherboard’s user guide; the Boot Menu access key(s) should be mentioned somewhere. Press the key that enables the Boot Menu Once the Boot Menu appears on the screen, choose your USB drive. It might be listed as USB HDD, Removable Device, or by the brand name of the drive. Select it and hit Enter. Choose to boot from a USB flash drive in the Boot Menu Once you’ve pressed Enter, your PC should boot from USB.

2. Boot from a USB drive using Windows Settings (without BIOS/UEFI access)

If you want a method that doesn’t require going into BIOS or UEFI, you can force Windows to boot from USB. Start by plugging in the bootable USB flash drive to a USB port on your computer. Then, it depends on whether you’re using Windows 11 or Windows 10:

3. Boot from USB by changing the BIOS/UEFI boot order

If you want your PC to boot from a USB drive by default (for example, on every restart), you need to change the boot sequence in BIOS/UEFI. Here’s how to do that: To begin, plug your USB drive into a USB port on your computer. Then, restart your PC. As soon as it powers on, repeatedly press the BIOS access key. Although the manufacturer of your PC or motherboard can assign any key for this action, commonly used keys include Delete, F1, F2, F10, and F12. If none of these work, you can find the right key to press in the manual of your PC or motherboard. Press the BIOS/UEFI access key repeatedly TIP: On modern computers that use UEFI instead of the traditional BIOS, the system might start up so quickly that it’s hard to press the required key in time. If that happens, the solution is to access the firmware settings from within Windows. If you’re using Windows 10, follow the instructions in this step-by-step tutorial on how to enter the BIOS from Windows 10. For Windows 11, check out this guide that explains 7 ways to access the UEFI/BIOS from Windows 11. Once you’ve entered the BIOS/UEFI, browse through its configuration options until you find a page called Boot or similar. There, you should see the boot order your computer uses. In this list, you must choose the USB flash drive as the first device used for booting. Remember that the USB option can be named differently on your PC, so check for Removable Devices, USB-HDD, or similar names. Selecting the USB flash drive as the first boot option is usually done using the arrow keys. However, on some systems, you might need to use the +, -, F5, or F6 keys instead. Your BIOS/UEFI should display some helpful information about this topic. Moving the USB flash drive to the top of the boot order list After you’ve selected the USB flash drive as the first boot option, save your settings (usually done by pressing F10 on your keyboard) and exit the BIOS/UEFI environment. Your computer will restart and then automatically boot from the USB flash drive. Saving the settings in BIOS/UEFI IMPORTANT: If your computer uses UEFI, you might not be able to make the previous settings. In that case, you must first disable (temporarily) the Secure Boot option. This option can also have different names depending on what the manufacturer wanted: Legacy Boot or Legacy Support, CSM or Launch CSM, and so on. Choose to enable the options that start with Legacy or that have CSM in their names.
