restoring windows 7 boot after installing opensuse 11.4

Hi guys .
recently I’ve installed Opensuse 11.4 dual booting beside windows 7 . now I want to restore windows 7 boot to remove OpenSuse 11.4 …
I’ve tried many ways to remove grub and restore window’s boot . I tried bootrec /fixmbr and bootrec /fixboot but in when it comes to the last step it says (cannot find system path )
I also tried nt60sys method to restore windows boot and it failed 2
sound like the grub installed is rock solid one :slight_smile:

The situation you talk of with Windows 7 is similar to fixing Windows to install Service pack 1

openSUSE Dual Booting with Windows 7 AND Loading Service Pack 1 for Windows 7

Thank You,
