Backup booting

    I have a rsync backup on my computer at /dev/hda7. The backup came 
from /dev/sda2. The backup on hda7 was taken from sda2 to a USB hard 
drive. That was then sent to hda7.

    Both /etc/fstab and /boot/grub/menu.lst were changed to reflect the 
new location on hda7. Copied the menu.lst from the new to the current 
menu.lst so it can be tried easy.

    When I boot the backup it goes quite a ways but errors out looking 
for some std USB things. That seems to be wrong. Here are the parts of 
both menu.lst and fstab for review. I am certain menu.lst is working.

menu.lst:

# backed up version on /dev/hda7

title        Ubuntu 7.10, kernel 2.6.22-14-generic backup
root        (hd0,6)
kernel        /boot/vmlinuz-2.6.22-14-generic 
root=UUID=16ccb569-10ba-43c2-856e-f2cce1307a29 ro
initrd        /boot/initrd.img-2.6.22-14-generic
quiet

Now fstab is from the backed up system and is:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

As you can see I have blocked most of the mounts to /media just to make 
it simpler.

    Does anyone see how init is hitting a error it can't go beyond?

What was the hard part, getting grub to start the right kernel is 
working fine. There is something other wrong.
