Vista Installation Help

I am upgrading my desktop (XP) to Vista Ultimate. The upgrade went
well until the end when it restarted I get a black screen saying
something like it failed to start because of a change and gives me the
choice of normal start up, start in safe mode, start with networking,
etc. I tried normal start, I tried taking the installation CD out and
putting it back, etc., etc and could not get the computer to start!
Vista Upgrade Advisor shows: Issues with Microsoft Interactive
Training, Nortel Networks, Dell Cineplayer, Dell Inc. Utilities,
Windows Messenger.
When I run the installation disc the compatability issues that are
listed are:
Ports (COM & LPT): NetMos PCI ECP Parallel Port (LPT3)
Microsoft Interactive Training
Dell Media Experience
Windows Messenger 5.1
