http://ubuntuforums.org – OK. Novice and new and you will see below how much of a mess I've created. My windows recently refused to boot, instead taking me to the BSOD and repeatedly trying to reboot. So, using a backtrack 5 KDE disk I have I downloaded Ubuntu 12.04 and unetbootin. Ok, so I Installed ubuntu (keeping windows) , on a new partition. It wouldn't boot, it gave me an error as soon as the computer went on. (Unlike the windows issue where it ran a good minute through the boot cycle before BSOD and restarting) I decided to install ubuntu again, over windows, figuring I'd deal with fixing windows later ( (Hardware)
