Another case of "Black Screen" woes

Experiencing same issues as multiple other posters here. Using a new SATA
drive (no RAID). Installed XP Pro, then tried installing Vista from DVD
choosing "Upgrade" option. Install proceeds until the first reboot point, at
which the system will hang at a black screen. Restarting and using "safe"
mode shows that the last driver loaded prior to the "black" screen is the
disk.sys driver.
I have redownloaded and reburned the Vista .ISO image as per previous
posted suggeestions. I have also burned the image at 2x speed.
A "clean" install of Vista will not work either.
I read in a previous post about forwarding log files to Microsoft for
analysis. Should I do so in this case? Can anyone offer any additional
suggestions?
Thanks..
