Windows won't boot after new MB installed

I installed a new motherboard for my Windows 7 Home Premium system and was surprised to find Windows won't boot now. I tried repair option from the install disc but didn't help. I tried the in place upgrade but after selecting the Install now option I end up with a message that the system was booted from the install disc and I need to start Windows normally and then insert the install disc again which of course won't work when Windows can't boot.

I made a new install on a test hard drive to check my motherboard and it is working fine. What can I do? I would like to boot on my regular drive with all my data and programs and not have to go through the long process of finding and installing everything anew.

Thanks. I will have to re-install my old MB and go through this process. I knew that Win 7 doesn't use HAL so this must be the new process. I do have an old image (Acronis) stored on another system but restoring it to a different system can be a problem too unless you have the Plus version which I don't.

If you can't SysPrep on the old hardware, run Paragon Adaptive Restore CD on the HD before trying to start it again.

Keeping a SysPrepped image of your favorite install or a PAR CD will assure you can always move it to new hardware ad infinitum.

may be posted twice - got through Sysprep, changed motherboard and booted up went through a couple of steps and got into an error loop "Windows could not complete installation, etc." pressing ok just reboots and goes into the same error process ad infinitum. Can I use Paragon Adaptive Restore on the new MB to get a clean boot? Need to find a place to download it without signup or other hassles.

Yes running PAR CD on the HD should startup Win7 on new hardware if it has not become corrupt.

You may have to complete your clean install which is never a compromise but always a fresh start, like getting a new computer except better. Reinstalling Windows 7
