I have a dual boot desktop running Windows XP and Windows 7 64-bit (each OS on separate hard drives). My graphics card is a EVGA Nvidia GeForce GT 630 (DVI and HDMI). I popped in an Ubuntu 11.10 64-bit install disc to try it out without installation. The screen displayed a list of things but then got stuck at a certain point with a cursor flashing at the bottom. I restarted the computer and now my display won't turn on. I can't access anything now in Windows (Windows dual boot option screen, boot menu, etc.) or Ubuntu since my screen won't turn on. I don't have a VGA connection on the card or on the motherboard. Any possible fix for this or did I just make a huge mistake by trying to use Ubuntu?
