Running Fedora 35 and trying to fix installed boot files on a third drive.
~]# grub2-install /dev/sdc
grub2-install: error: this utility cannot be used for EFI platforms
because it does not support UEFI Secure Boot.
Secure Boot is turned off in the bios. The boot is from UEFI.
MBR is not a component of UEFI booting. The UEFI BIOS looks to the \EFI directory
on the ESP partition. Instead of grub2-install, do:
dnf reinstall grub2-efi grub2-efi-modules shim
after appropriately following the directions on

No mention of MBR as the drive is GPT. Totally UEFI system, four drives
three OS. I was suspecting a problem with the boot sector, but on
removal of all drives but the one, it boots. Adding the drives one by
one to see the point of digression.
