Second: How to boot from USB in UEFI computers.
If your computer has a UEFI firmware or you failed to boot it from USB in first method, do the followings:
power on the computer and press F2 key repeatedly to open BIOS settings:
This is the list of common keys used to open BIOS settings for different brands for desktops, laptops and notebooks:
Once you are on the BIOS menu, take a video for the entire BIOS settings using your mobile before doing any changes, so you can revert new changes back to previous settings once you finish troubleshooting.
Use arrow keys from keyboards to navigate between panels and items or read the instructions from the bottom of BIOS settings.
Locate secure boot or fast boot and disable it
Go to Boot tab and change USB Boot option to Enabled or on.
- In some Asus or similar laptops with UEFI BIOS menu like this,
you have to enable Compatibility Support or CSM mode,
in order to disable secure Boot.
In some computers, you have to change Boot Mode to Legacy support,
then enable USB legacy or any related settings if available.
If you are unable to enter Boot menu as on the first method,
you have to change the boot order so USB takes the first position in the list.
Use F5 and F6 or follow the instructions from your screen to change the USB boot position to the top.
In Asus UEFI/BIOS utility and similar menus,
you can drag and drop the USB drive in to the top of the boot list using you mouse.
Navigate to Exit panel and select, Save Changes option.
Also you can save changes by pressing F10 or similar key
according to what you can see in your BIOS menu.
If the USB drive not shown on the boot list, make sure that:
The USB is not disabled in boot menu or any menu.
The USB scheme is applicable to your disk scheme (i.e. MBR or GPT)
The USB drive is not corrupted or unbootable
In some cases, you have to save changes and reboot into BIOS settings...
in order to see the USB drive on the Boot menu.
Also you can try to plug the USB pen drive to another USB 2 port in your computer.
Some mentioned settings may or may not available in your computer,
or may be available in other names rather than the mentioned names.
Search for any of the following settings and make sure it’s Enabled or set to On:
CSM Legacy Support Legacy CSM Launch CSM
If you have a UEFI/Legacy Boot option, set it to Both or Legacy Only.
