UEFI boot is a different bios then MBR. You need a DOS partition that contains an EFI directory that gets mounted on /boot/efi. In the EFI directory is two directories: BOOT and your OS, i.e. "rocky" or something. BOOT needs a couple files, on mine, it is BOOTX86.EFI and fbx64.efi "rocky" needs a few files from grub, grubx64.efi, grubenv, and others. > > > Thanks, > > -kb > > _______________________________________________ > Discuss mailing list > Discuss@lists.blu.org > https://lists.blu.org/mailman/listinfo/discuss > _______________________________________________ Discuss mailing list Discuss@lists.blu.org https://lists.blu.org/mailman/listinfo/discuss
