My working OS uses grub, but I've just installed Sabayon 5.5, which uses grub2, on hda10. I want to keep using grub until I've got time to RTFM on grub2, so I installed the Sabayon bootloader on hda10. I should be able to point grub at the partition and boot indirectly, as with Windows, but after following the grub 'info' page I get an error message. Can anyone point to the error in the following grub script:

title hda10 110330 Sabayon 5.5
rootnoverify (hd0,9)
makeactive
chainloader +1

At boot this gives the following:

Booting 'hda10 110330 Sabayon 5.5'
rootnoverify (hd0,9)
makeactive
Error 12: Invalid device requested

With thanks for all replies.

Lose the makeactive - illogical (um, unsupported ) for a logical partition.

I have not used Sabayon but I think I read that it needs to reside in a primary partition.

Got it in one! Many thanks.

And thanks to Larry for the warning, but no, it boots OK in the logical partition.
