Windows 7 beta install - black screen? -

Ive officially downloaded form Microsoft, tried to do a duel boot with Vista Ultimate on one partion and W7 on the other but after install all Im getting is a Black Screen with the windows 7 build no and for testing purposes only text in right hand corner, Ive installed several times and burned of the ISO disk several times, but still same problem, any suggestions to what it can be will be very useful.

is you copy currupt ? some times in the past i have disconnected a hard drive with a system and connected a differant hard drive and installed a differant system try it if you are able i downloaded w7 last night it installed first time 2.44 gb iso yes dual boot as well

If you downloaded officially from MS, and are a beta tester why would you ask this question here? I m sure you know how to report bugs. This sounds like a big bug. Good luck
