I purchased a Dimension E520 from Dell recently and it came with Xp
Home. I tested it by starting it up making sure the home edition was
running ok.  Our company had purchaed several copies of full version xp
pro from a different source and I had planned to use one of those to
upgrade this E520 to Xp Pro. As I have done with numerous other
computers, I booted using the xp pro cd and it started setup process. I
get the normal blue screen and it starts to copy the setup files. As
soon as it finishes copying the files I see a "starting windows setup"
at the bottom of the screen. At this point I get a blue screen of death
and it tells me that windows has been shut down to prevent damage. I
have tried 3 different cds (including one oem xp pro from dell) and had
the same result. If I put in the xp home cd that came with the setup
works and I can continue with the setup it works. Is there some sort of
new proprietary issue here?

Tks, Sam
