Accidentaly I switched my running computer off and after that I cannot startup my Ubuntu 10.4 64 anymore.

The startup stops already at the very beginning at "Boot from CD/DVD" and shows a blinking cursor. I tried to rescue with the alternate install disk and to write the Grub to the disk but this fails. [-o<

Attached are the results of a Boot Info Script.

Please help me out, I need to work. Please be aware that I am a rookie. [-o<

It is much easier for us if you post the results like this:

My problem is solved. After long time puzzling I found out that the swap was corrupted. With swapoff and makeswap I repaired. After that I could reinstall Grub and could start up normal
