I'm fairly new at linux and Ubuntu so I'm having some trouble figuring out a particular issue.

So I recently installed Xubuntu as a second partition on a laptop running Windows 8.1. But when I restarted my laptop I ended up in the Grub prompt. I have come as far as finding out it has something to do with setting the kernel manually and have managed the following:

set root=(hd0,gpt8)
linux /boot/vmlimuz... root=/dev/sda8/
initrd /boot/initrd.img...

I did this and was left with

"Error: no suitable mode found
Booting however"

Anyone who can help me here? And please tell me if any more information is needed!

It boots? This normally should be due a module you didn't loaded insmod ext2. Also, have you tried to run sudo update-grub2? –  Braiam Nov 22 '13 at 15:58
Sorry, I mean it froze after that message :) –  niels bross Nov 22 '13 at 18:06
