grub appears to prefer the default, whatever that is. Certain values
it appears to accept, such as (hd1,1), but then none of the following
steps work. In other words, if I don't given the "root" command, then
the following works.
FWIW: In the original menu.lst the 'root' command pointed to (hd4,0).
But if I try to enter that on the cmd line, it says "disk not found".
When I boot from the DVD, my OS partitions are displayed by fdisk on
sdc, but they were originally on sdd. ;(

Ok, this works..

This works too.

This starts to work, I get a flurry of messages about things loading,
but then something appears to go wrong, ie:
mount: could not find file system '/dev/root'
mount: could not find file system '/proc'
mount: could not find file system '/sys'
Switchroot: mount failed
Booting has failed

Yep, I had similar problems going from FC5 to FC6, but for some reason
it was easier to solve that time around. Would doing a fresh install
of F7 solve things? (My home partition is separate).
