If you're using Clover Boot Manager with a flash disk plugged into a USB port, and the list of bootable drives doesn't show "UEFI"
The flash disk might not be read or detected The Clover Boot Manager NVMe.
This can lead to a failed boot and a blank screen.
The cause (for older computers):
Some older computers use a Legacy Boot Manager setting.
This setting can prevent Clover Boot Manager from loading, resulting in a blank screen.
The fix:
Enter your BIOS settings (consult your motherboard manual if needed).
Find the Boot Mode settings and select "UEFI." The exact menu names might differ depending on your BIOS version, but look for options similar to those shown in the video (if provided).
Once you've located and changed the Boot Mode to UEFI, save your BIOS settings.
Reboot your computer.
By enabling UEFI boot mode, you should be able to boot from your flash disk using Clover Boot Manager.
