I have a Dell XPS M1330 Laptop sitting here that had the HD die. It now has a replacement drive and Im trying to install Vista. It gets past the initial black and white loading bar but once it gets to the green bar it just does not do anything! Ive let it sit there for more than an hour with nothing occuring. Ive even gone though the trouble of making a bootable Vista USB key and it does the same thing. I also plugged in my bootable linux key to run memtest and let it go for a couple passes. No errors.
