I recently hit a relatively common problem whit the Ubuntu 16.04 installer, that misconfigures the location of the GRUB folder [0]. In such cases the system boots into a rescue shell with the following messages: error: file '/grub/i386-pc/normal.mod' not found.
Matches :
=> Grub2 (v2.00) is installed in the MBR of /dev/sda and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos1)/grub.
the missing "/boot" in the path means that this GRUB was installed with /boot on a separate partition.
This means GRUB was able to boot, but it is looking for its modules in the wrong place. The well known solution is to instruct GRUB on the fly on the location of its modules [1]. In my case this is: grub rescue> set prefix=(hd1,msdos2)/boot/grub
meaning that another GRUB was installed on another drive (hd0 is always the boot drive in BIOS boot) with /boot in the root partition. Matches :
=> Grub2 (v2.00) is installed in the MBR of /dev/sdg and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos2)/boot/grub.
My guess is that the system is booting GRUB in BIOS/legacy mode from sda, which contains a remain of GRUB from a previous installation, not from sdg. Fortunately for you, the two GRUBs are compatible enough.
Also, it seems that /dev/sdg contains both EFI and BIOS/legacy GRUBs. _______________________________________________ Help-grub mailing list Help-grub@gnu.org https://lists.gnu.org/mailman/listinfo/help-grub
