The 'Error 18' indicates he is using Grub.
Grub also uses the BIOS to load it's 2nd stage or 1.5 stage.
If there is some free space right after the MBR (which is usually the
case), then Grub places it's 1.5 stage there. But if there is no space
(some partitioning programs don't leave free space) then Grub's 2nd
stage must be on a partition where the BIOS can read it.
