My Dad's PC was having problems. I think it was a mistake to get Windows 8.1 installed in the first place, to be honest. It's way too fussy.

Anyway, he was about to wipe the entire thing, and I suggested having a look at Ubuntu.

I did the following:

  • Tried to install via download from Firefox... but his PC was so flaky I couldn't be sure what was going on at times. Lots of pop ups etc. despite adblock being installed.
  • I created an Ubuntu trial DVD and ran that. He liked the look of it, so from within that I installed 12.04.
  • When it restarted I got a grub rescue prompt. I have literally no idea what to do next.

It says :

error: no such device: 4376b2fc-07c9-4e08-bc3c-b8e41dfd8888.
grub rescue>

I had hoped to have a dual boot option at start-up, and then from Ubuntu was hoping to be able to move files from the Windows partition.

I'd be grateful for any advice.

I ran a couple of commands using the Ubuntu loader DVD.

When you installed ubuntu did you select the option to install along with windows8??? –  Roney Thomas Feb 2 at 14:59
    
Yep - The idea I had was to have both available upon boot. On my laptop at home I have it defaulting to 12.04, but I could switch to Vista if I was feeling like hurting myself. That process was pretty straightforward but on my dad's computer it became complex, and quick.....I'm half convinced that the constant pop-ups etc. have somehow caused me to make an error. –  user242799 Feb 2 at 17:12

1 Answer 1

Try to reinstall the grub by using an Ubuntu Alternate CD. If not, try to burn on a DVD Boot-Repair.

I too had problem with Win 8.1 and Ubuntu. Especially on UEFI Device, sometimes Windows just doesn't want Linux to install side by side with secure boot on.

Thank you - it certainly wasn't as simple as my home setup (old Vista laptop now running brilliantly on 12.04) and no hassles on installation. –  user242799 Feb 2 at 17:14
    
Does this info help? –  user242799 Feb 3 at 16:43
