I'm a very low-level geek and have a little issue migrating to a Dell desktop a friend of mine gave me. My Gateway is maxed (1 GB Ram, single-core Pentium CPU), so he gave me his Dell with a dual core CPU and 4 GB. All I want to do is take my Western Digital HDD and put it into the Dell. But when I boot it up, it goes into a loop and can't fully boot windows. I assume I need some drivers or something for the Dell installed on the HDD?

I figure it's an easy fix and something that I could do if someone points me in the right direction.

Thanks a ton.
