I have a HDD with Ubuntu 7.04 which was installed with the HDD
connected as primary master (which with my Ultra ATA card is
referred to as /dev/sda under Ubuntu, as /dev/hde under Fedora).
Ubuntu is in the first partition, i.e., /dev/sda1.

I want to use a HDD with Fedora Core 6 installed as primary master
and move the Ubuntu HDD to secondary master. There's already a
HDD with Windows XP connected as primary slave.

Figuring that the Ubuntu HDD had its own grub bootloader, I added
this stanza to /boot/grub/grub.conf on the FC-6 HDD:

title Ubuntu
rootnoverify (hd2,0)
chainloader +1

However when attempting to boot Ubuntu, I immediately get the
following:
-----------------
Booting 'Ubuntu'
rootnoverify (hd2,0)
chainloader +1

Error 13: Invalid or unsupported executable format
Press any key to continue
-----------------

I've tried tweaking the Ubuntu /boot/grub/menu.lst and /etc/fstab
files but it makes no difference - I don't think it ever got that
far.

Any ideas as to what could be wrong? Thanks for your help.

The bootloader might be in the MBR, not the first partition. Try
rootnoverify (hd2)
chainloader +1
or
root (hd2,0)
kernel /boot/vmlinuz-2.6.whatever
initrd /boot/initrd.img-2.6.whatever

Ahah! The rootnoverify(hd2) worked like a charm.

Many thanks Bill.
