GRUB error 13 after Sabayon install [Solved]

[questio verum]

I installed Sabayon 3.5 this past weekend and now cannot boot into Ubuntu Studio. I've been using linux exclusively for the past year, but decided to reintroduce WinXP when a friend gave me a pile of new games. So I set the drive up with XP, then installed Ubuntu Studio 8.04 (non-LVM), configuring it to use the Windows partition to store the bootloader (GRUB 1.5). Once both of these were verified as functional, I installed Sabayon 3.5 using Ext3 as the filesystem. After installing Sabayon and rebooting, I was able to boot into Sabayon and Windows XP, but not Ubuntu Studio. After selecting Ubuntu Studio from the GRUB menu, I get this error:

Booting 'Other Operating System – Ubuntu Studio'

rootnoverify (hd0,5)
Error 13: Invalid or unsupported executable format

Press any key to continue...

I think I've got two grub.conf files installed; each in a different partition. My grub.conf as installed by Sabayon is:

# grub.conf generated by the Sabayon Linux Installer

I viewed the partitions with gparted and it looks like Ubuntu Studio is on sda6. I would like to get all three OS'es functioning.

If anyone can help me out with this, I would be grateful.
THX!
