Did you see my ninja edit? Sorry...  :-[

Edit: Thinking about it, if Kubuntu is the eventual primary OS, we're better off aiming for that at this stage rather than doing the same changes twice. Go for these commands instead (just reboot if you're halfway through):
Code: [Select]
set prefix=(hd1,1)/boot/grub
set root=(hd1,1)
insmod linux
linux /vmlinuz root=/dev/sdc1 ro
initrd /initrd.img
boot

Again, this will fail if Kubuntu isn't on sdc1 (and GRUB doesn't think it's hd1,1 but it's impossible to work out which is which at this stage)

Edit 2: I'm heading out now, and won't be online for a few hours/tomorrow. If you manage to get into Kubuntu, fire up a terminal and execute:
Code: [Select]
sudo update-grub && sudo grub-install /dev/sdc && sudo grub-install --recheck /dev/sdc
That should do the business, fingers crossed!

Done all that and I thought it'd locked up with a problem with the usb ports but when I pressed 'del' it went on to boot to Kubuntu but it's not booting properly... It's just stuck on the boot screen with 'Kubuntu 12.04' and fhe r dots

I pressed Ctrl +alt+del and saw 'failed to boot' flash up.

Just saw your last post  and entered  the commands and it's booted to Kubuntu
Now entered the update commands... All seems OK, now to reboot...

Fingers crossed...

The last time I was able to get into the BIOS, it was sdc (the 500GbHd).

So you're having problems accessing the BIOS ?

Yes.
Don't know if this is of any relevance but I was looking for the fstab file and found 4, so I'll put up all 4, the one I was looking for was the one listing the drives.
Although they show the same name, the files are different.

So you turn your PC on and immediately hit and hold the "Del" key (or whatever the BIOS access key is .. and what happens ?

Do you know the PC make/model or motherboard make/model ?

Does it still say exactly this:
Error: no such device: 194ee891-90aa-42e8-b1c3-1ed0fc143a0e.
Grub rescue>(cursor)


If so, boot to a LiveCD/LiveUSB (or any accessible Linux) and post he output from:
Code: [Select]
sudo blkid
