Try info grub (or you might find pinfo grub easier. Or try one of the
graphical interfaces) and follow Troubleshooting.

# 15 : File not found
#      This error is returned if the specified file name cannot be found,
#      but everything else (like the disk/partition info) is OK.
(OK: it could say *which* file wasn't found...)
# 22 : No such partition
#      This error is returned if a partition is requested in the device
#      part of a device- or full file name which isn't on the selected
#      disk.

Hope this helps,

James.
