To try to identify the problem I had with "error: no such device:
bfdeb6d6-0b77-4beb-a63d-bdc3e455b8ea", I removed all but the boot disk and
edited the boot entry for Linux on my ext3 /boot filesystem when GRUB
started:

menuentry "Debian GNU/Linux, Linux 2.6.30" {
        set root=(hd0,1)
        search --no-floppy --fs-uuid --set
bfdeb6d6-0b77-4beb-a63d-bdc3e455b8ea
        linux   /vmlinuz-2.6.30 root=/dev/hda7 ro
        initrd  /initrd.img-2.6.30
}

to include:

SET DEBUG=PARTITION

before the "search" line.

fdisk reports the following:

To help clarify what output I experienced from GRUB, I obtained a hex dump
using fdisk, with some interesting lines with "*" underneath them:

GRUB 1.96+20090613-1 which I compiled from svn reported (what didn't scroll
by):

As usual, if I edited out the "search" line, I could boot normally.
