I have an Acer t135 all stock. I had XP and xubuntu both on one hard drive, and this morning I get a message on xubuntu to download some updates. I download and install them. Then it says to reboot. So I reboot then while its turning on it says Acer aspire like it normally does and after that it says something about grub and a bunch of numbers. At that moment I new I was screwd. So I put in the recovery CDs my computer came with to reinstall XP. It all goes well until the end when it says remove system CD and press ok to configure. So I remove the CD and press ok. The computer then reboots on its own and keeps turning on and off by itself enlessly. so I turn it off by holding the power button until it shuts down. I press the power button and it keeps turning on and off again. I do get the option to press del to enter setup and f12 to boot from specific location though. What do you guys think I can do now? Any help would be much appreciated.
