I try installing Ubuntu 13.10 next to windows 8 on my laptop, but I was all the time booting on windows 8...so I execute a boot repair from a live USB... and since then I'm getting a nice black screen with Grub rescue...
Here is the URL boot repair gave me.
I know witch of my partition is the linux one on my disk can read what is on with: ls (hd0,gpt5)/
But that's pretty much all what I can do! (I'm a begginer with linux and I can't access to the bios to modify any setup for the moment...)
Thanks for your help!
