Just messed up today with MBR in Win 7 Ultimate x64 .
I had no backup/restore point.
I did everything possible with repair- not worked. You know, there were thousands of apps
I hate to get the feeling of installing the big programs like PS CS4, Office...
Then popped up Win 7 DVD, installed in the same directory ( I knew , Windows will create Windows.old folder with all programs, settings...) with same user name, password, Computer name.
It installed as usually, I first activated it. Then downloaded "take ownership" reg file. I went to C: drive. Took ownership one by one. The Windows folder took 15 mins to be completed.
Went to Windows.old . Cut the folders one by one and pasted them in right places.Several prompts came...its still running...it will take 6 hours or like that.
All programs are running, I just checked PS CS4 ...voila!
I used cut instead of copy, because, I can see which files are not copied. I will copy them later.
Hope it helps someone!
I wanna hug the person who made the reg file
