I have a new computer ACER Aspire X3960 which came with Windows 7 preinstalled. I made a new partition where I installed Windows XP and then I installed in new logical partitions (a Swap, a / and a /home partition) Ubuntu 11.04.
At the end of the process, the computer enters the very first screen where it says "press DEL to enter BIOS setup, press F12 to enter BOOT options".
After a few seconds, the screen goes blank, the computer beeps and then it presents the same screen again.
It doesn't even ever go to the grub options of which operating system I want to start. It just loops there forever.
I tried to fix the (eventually damaged) grub following these instructions (unfortunately in german) http://wiki.ubuntuusers.de/GRUB_2/Reparatur from a LiveUSB, which I'm also using to post this question.
Now I found here that someone asked for the results of the Boot Info Script. Here is mine (I hope I did right in trying to upload the file):
Can anybody help? Thank you very much.
