I'm installing Vista on a new drive. I boot it from disk during start up, and it goes swell for most of the part, then, it restarts, and goes back to the installation, and continues, all during the "completing installation" part. Then, about 74% across the bar, it restarts, but it doesn't tell me this time, like it did before with the count down, it just restarts, my PC gets back to the safe mode window, and when I go into start normally, it says that there was some kind of error during installation, and I had to go back and do it again. The first time I installed it, the screen just remained black after the restart, went past the boot up stuff, but the installation screen never appeared, so I had to restart. What could it be?
