PC won't boot after sysprep

I built a Windows 7 image and forgot to disjoin the domain prior to running sysprep.  I realized my mistake and was going to boot winodws, disjoin and run sysprep again.  When Windows is loading I receive the following error:  

"The computer restarted unexpectedly or encountered an unexpected error.  Windows installation cannot proceed.  To install Windows, click "OK" to restart the computer, and then restart the installation."

As soon as you click "OK" the computer reboots and the same error occurs.

I tried to boot to the installation media to run a repair but I receive an error before it even boots.  The error is: 0xc00000e9 An unexpected I/O error has occurred.  

I have ran diagnostics on the drive and it appears to be good.  

Any help would be much appreciated, I really don't want to recreate the image again from scratch.  Thanks.
