I have the same problem so i didn't want to open a new thread.
Windows 7 can not pass the "Starting Windows" screen.
And my last successful Bootime was also the 19/01/13... Weird...
I have a dual boot PC one system with XP System dedicated to Audio,
& the other is a Windows 7 Ultimate x64.
I tried running a Command Prompt with the 'SFC' commands a lot of times,
And it helped once and it's not helping anymore...
I also tried the "System recovery options" a few times with no luck.
You think i can use this: Restore MBR
To try fixing the problem?
Or any other suggestions will be most welcome!!
