So I went to install this wireless card into my computer. I had to take out my graphics card to get at this phone network card and take it out. So I took both of those out, popped in the network card, popped in the graphics card, and booted. The BIOS screen comes up, but then it just goes black and says "DISK BOOT FAILURE." and doesn't do anything. Did I fuck my computer up? It sounds to me like it isn't able to boot from the HDD. I'm running Vista on an HP computer with 2GB DDR ram and a 3.2GHz duo core. Please help my mom is touching the computer.

Nevermind, I figured it out. I had knocked a cable for my HDD loose.
