I face another problem on one Notebook (Acer Switch 3).
When I boot from the usb I get the message "Could not open "\EFI\BOOT\fallback.efi": 14".
I tried to turn off the secure boot option in the BIOS, I also tried different usb-keys and kernels (x64 and also not the x64).
BIOS is on the newest version.
Someone who also got this error?
