New CPU & MoBo, same HD

Yes, that's why I specified Uninstall and not Disable. The driver will still try to load, hanging the install, if it isn't not uninstalled before install proceeds.

This is always a long shot however, but worth a try.

Thanks. I uninstalled the video driver - still no go.

Will the HD work in the old rig at this point?

It should. You wanna try SysPrep again? The author of our tutorial Kari can help you with specific issues. SysPrep to move HD to another computer

You can also use PAR, or Acronis True Image with Universal Restore to back up an image which will work on new hardware.

How would I best interact with Kari?
If I back up the image, does that save everythiing on the HD - program, documents, etc?

I put the HD in the old rig - won't work. I get the window, "Windows could not complete the installation, etc".

Sounds like SysPrep failure. You can PM Kari by clicking on his name in Tutorial author bar.

Try copying out your files using DVD or REpair CD: Copy & Paste - in Windows Recovery Console

While in DVD/CD REpair console, run Startup Repair repeatedly. Does it find an installation to Repair? If not, from Command Prompt run bootrec /fixmbr and bootrec /fixboot then try Repair again.
