So here is the deal, I had been running Ubuntu 8.10 from the time it was released until about 2 days ago because when I went to 9.04, I got a warning saying that 9.04 didn't support any drivers for my video card. Well I decided to go ahead and upgrade to 9.10 so that I can upgrade to 10.4 LST once it comes out. Everything seemed to be fine but I turned it that night and left it running over night. When I got up the next morning, the screen was black and the computer was not responding. When I tried to restart it and it could not finish loading the OS. It made it about half way though and then the screen just went black. YAH!!! So far the only way I have been able to do anything with it was by having a Ubuntu boot disk in the CD/ROM when I start the computer. With the disk in the drive, whatever file or driver that the OS seems to be missing, it uses the one of the disk and loads just fines. So, no that you know how my day has been let me get to the point, does anyone know if the Ubuntu installer has a repair function and if not, can I just reinstall Ubuntu and let it reload the OS files without it deleting all of my files?
