SOLVED Re: boot stops after displaying "Loading initial ramdisk..."

Thanks for the answers

I finally solved the problem with ubuntu from a live usb stick over the 
existing installation.

I was happy enough that the old installation used only one partition, so 
I used it as / without formatting.

This preserved all my data, but "uninstalled" all modules that where 
installed, as the existing system folder where wiped.
