12 ERR_DEV_VALUES Invalid device requested
13 ERR_EXEC_FORMAT Invalid or unsupported executable format (not bootable) - the ISO(?) you are trying to boot from is not bootable - maybe it is an Update CD instead of an Install CD\DVD? Maybe BIOS has the 128GB USB drive limit bug and file is too far on drive?

26 ERR_SYMLINK_LOOP Too many symbolic links
27 ERR_UNRECOGNIZED Unrecognized command

37 ERR_DEL_MEM_DRIVE You should delete other mem drive first or use `--mem' option to force the deletion
38 ERR_DISABLE_A20 Failed to turn off Gate A20!
39 ERR_DOS_BACKUP GRUB was not booted from DOS or the backup copy of DOS at physical address 0x200000 is corrupt

41 ERR_EXTENDED_PARTITION Extended partition table is invalid or its CHS values conflict with the BPB in a logical partition
42 ERR_FILENAME_FORMAT The leading DEVICE of the filename to find must be stripped off and DIR for set-root must begin in a slash(/).

61 ERR_MANY_FRAGMENTS Too many fragments

65 ERR_PARTITION_TABLE_FULL Cannot use --in-situ because the partition table is full (i.e. all the 4 entries are in use).
