I just finished building my first computer and was installing vista. I think it was transferring files to my HDD when my computer reset. Now this happens every time I boot when the HDD is plugged in, but when the HDD is not plugged in I can't install windows onto it. I've looked around on the internet and still have no idea what's going on. It could have something to do with the boot priority or the fact that my CD/DVD drive seems to be listed as a master HDD. Keep in mind that I have no idea what I'm doing and might have just messed up a cord placement or changed a setting in BIOS. Also, plugging in the HDD after the computer has been turned on would be a bad idea, right?
