Hi,
I'm not sure why you are not getting the "Install" and\or "Repair" screen...
You are using bootable Windows 7 installation media, correct ?
None of that stuff will be of any benefit if you did not "Create An Image", or create a "System Restore" point...
You may have run the commands before, but not since making some other changes, as far as I remember anyway.. Especially setting the partition "Active"...
If you have a image, or a restore point saved, you could try that...
I doubt that a "System Restore" would be of any benefit, but an Image most certainly would...
