I have a P4 standard desktop with Win XP and Ubuntu 7.10. When I boot I get the choice of booting up in Ubuntu or Windows. I wanted to upgrade to 8.04, so I choose the 10 Gb Ubuntu partition that had 7.10 installed on it. Everything seemed to go well. But now when I reboot I get the message:
Error 22: No such partition
I can't get into Linux or Windows! It won't recognize any partition.
I desperately need help. Please tell me there's a solution to this which involves getting my Windows XP back.
