Hello. As you can probably tell I'm facing a somewhat common problem in the world of Windows computers; when I turn my computer on, it goes to a black screen with a flashing underscore/cursor. At first I thought myq problem was that I accidentally left my external hard drive plugged in, so I immediately unplugged it and rebooted my computer, however the problem persisted. I have a Dell 530S running Windows Vista Home Basic. I've read about putting in your boot disks but unfortunately, I do not have one. Any ideas of how I can fix my problem? Any feedback would be much appreciated.
