When I am trying to boot from my USB to install elementary OS, it shows me an error.

Could not open "\EFI\BOOT\fallback.efi": 14.

Can you help me?

  • I had to press tab to show options. I had seen boot so I typed it but it said "you need to load kernel first".

If you have a running linux system.

Plug USB

sudo parted /dev/sdX set 1 boot on
sudo mount /dev/sdX1 /mnt
sudo 7z x /path-to-iso -o/mnt/

Where X is your USB device (usualmente a)


Disable (U)EFI on bios and try.
