[ubuntu] Trouble installing 12.04.1, gparted shows /dev/sda as unallocated

view story

http://ubuntuforums.org – Here's the situation. I was dual booting win7 and ubuntu 10.04. I only use windows for games and because of win7's overhead I figured some games would run smoother under xp so I installed xp over it. I figured since I was reinstalling windows I should also reinstall ubuntu and bring it up to it's most current LTS, 12.04.1 While booting from the livecd and trying to install it, gparted suddenly shows my entire sda as unallocated and gives the warning: "can't have overlapping partitions". Running fdisk -l gives this output: Code: omitting empty partition (5) Disk /dev/sda: (Hardware)
