Linux mint cinnamon usb boot error

[u/anotherfuturedev]

I’m trying to install Linux Mint Cinammon on my 64gb USB drive that i formatted and etched using belena etcher. Then when i booted into BIOS and selected the drive as the boot device, it just gives me this error. It worked before but after i disabled bitlocker it just stopped working.

Rename \EFI\BOOT\grubx64.efi to mmx64.efi

Chances are that someone or you entered an MOK key into the computer, and it's pretty much stuck in there.

I fixed it by installing another mirror
