Package: grub-efi-amd64-bin Version: 1.99-26 Severity: important Hi,
I recently moved from grub-pc/GPT to grub-efi/GPT (dual boot with Win 8). After successfully installing Grub to the ESP and getting the UEFI to run grubx64.efi Grub (after welcomming me) complained: | error: invalid arch independent ELF magic. | grub rescue> At this prompt I could list the available partitions but I couldn't access their content via "ls (hdx,gpty)". Commands other than "ls" weren't accessible either, so the system was "user-unbootable". I assume Grub could not access it's grub.cfg or remaining modules. This happend when running grubx64.efi from an EFI-shell (v1) and with the normal UEFI boot sequence. However, when I used the previously installed rEFInd boot manager to launch grubx64.efi, Grub worked just fine. AFAIK rEFInd contains some file system drivers. So I installed Grub under a second label and added | --modules="part_gpt ext2" to the grub-install invocation. This produced a different grubx64.efi but with the same size as the first one. Accidently running the FIRST grubx64.efi, it now worked using either UEFI boot or EFI-shell! Does grub-efi use the GPT boot partition similar to grub-pc? If so, did grub-install add the ext2.mod there so that both Grub instances can now access the remaining modules on the (separate) ext3 /boot partition? If more information is needed I'll try to help but I tried an awful lot of things to get the UEFI/Win8/GPT/Linux/Grub thingy working, may not remember /all/ of it and am loth to do anything disruptive at this point.
