Solved Win 8 RP won't install- black screen

I downloaded RP ISO, burned to a DVD with ImgBurn, and tried to install over Win 7 Pro x64 using the 'Keep programs, setting' option. It goes into install mode (after uninstalling Security Essentials) and reboots a couple of times but never finishes. I wind up with a black screen. Upon resetting, it states that it could not install and would reinstall Windows 7, which it does.

BIOS is updated.

Attached it the setupact.log text file.

Hello Soon2beexpat, and welcome to Eight Forums.

Where did you get your copy of Windows 8 RP from?

the Microsoft site

I found the problem. I was reading another thread on this forum and the user said that his laptop screen was black but his monitor hooked up via HDMI worked. When I started the upgrade, I had my TV, which is plugged in to my computer via HDMI, turned off. So I turned it on on started the WIN8 disc again. Lo and behold, everything was running on the TV through the HDMI.

I'm happy to hear that you got it sorted. Thank you for posting back with your findings.
