Well finally got something to work with. Here is what a boot looks
like now using the /dev/hda7 partition. I copied this by hand on paper :-)
It stops for about 4 minutes with this showing:
[33.536208] sda: sda1 sda2
This worries me because the original is on sda2.
Then it went again and stopped after 4 minutes:
Check root=bootarg cat /proc/cmdline for missing modules, devices: ls /dev
Alert! /dev/disk/by-uuid/16ccb569-10ba-43c2-856e-f2cce 1307a29 does not
exist. Dropping to a shell.
It did.
So now to see where this uuid is located and go from there.
