I am using a Mac Pro 1.1 running OSX 10.5.8. I installed Windows on a partitioned second hard drive. Everything was going peachy for me when installing Windows 7 Home Premium until Windows needed to restart - this was after installation and before Windows had completed setup. It restarted the computer, I got the black screen with the Windows logo and text indicating that it was starting. Next thing it did was flicker a blue screen with white text for a split second and restart again. Then I got the same Windows starting screen followed by a black page with white text indicating that Windows did not shutdown properly. I had 3 options to start Windows in safe modes and another option to start Windows normally. I tried the start normally mode as it was the defaulted selection and got stuck in the same loop again. I also tried the safe modes and got a message indicating that setup could not be finished in that mode. So I have a partitioned hard drive with Windows installed but it won't start up so that setup can finish. Any help please as I was counting on this to used college critical software.
