vendors, Dell puts a small partition on the drive that maintains your registartion information. When you install linux, you may destroy that partition. Use custom partitioning and leave it alone. But, if you register with Dell much of the hassle is removed. Only windows will give you a hard time. Since it is Dell, they will provide new codes for activation as long as they can find your record. (They are pretty good at keeping records.) Again, only a concern if you ever want to use windows on it.
I was thinking of buying the above base dell model and was wondering if anyone had much problem installing linux on it. I know there will always be issues, but with a 30% restocking fee, I just want to make sure it is worth the risk. My understanding is that Dell always uses Intel Mobo's so I assume this is good. Any experiences?
