I'm quite new to Linux, so please bear with me. On my pc I had installed Windows 7 and Ubuntu 9.04, I then switched to Kubuntu 10.x, and yesterday I installed the new main update 11.x and I left the computer to finish installing, when I came back in a few hours I saw that my monitor was blank and looked as though it was unplugged, I checked all the cables, tried moving the mouse, pressing keyboard, still nothing, but as I said the monitor looked as though it was unplugged. Thus I pressed the reset button on my computer, the monitor started working as normally, but I can't boot into windows or Kubuntu.
This is all I can see on the screen: GNU GRUB version 1.97 beta 4 [Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device/file completions.]
I don't have live CD to repair it using CD. Is maybe there any other way? If not, how should I repair it using CD once I'll have it with me? Also is it possible to repair it or will I have to format the partition? If I should format, which partition, only the Linux one, and Windows 7 can remain the way they were?
Thank you for all your help and ideas.
