So here is the story: I had Win XP on my desktop and wanted to upgrade to a copy of Win 7 that I was able to get through school. I got an external hard drive and backed up all my important data. I burned a Win 7 disc from an iso. When I tried to run it from Win XP, I got an error that there wasn't enough room to make a new partition on my hard drive (it was just a single partition made when XP was installed). So I tried to restart and boot from the disc, but after I told it to boot from cd/dvd drive, the computer would just sit there with a black screen. Then I made a huge mistake and deleted the existing partition from inside administrative tools in the control panel. Now I get a BSOD when it tries to load Win XP and just sits there with a black screen when it tries to boot from the Win 7 install disc. I hope I was clear enough about my troubles. Any help would be greatly appreciated. Thanks.
