Major screw-up here and I need to find out how much trouble I am in.

I have an AD machine that is running Server 2008 R2, hyperv, DHCP and DNS. On the hyperv machine, I have a backup AD instance running along with a handfull of other server 2008 instances.

Sysprep was run on the hyperv machine instead of one of the instances.

I am attempting to bring the machine back up so I can try a system restore.

When I boot the hyperv machine, I get an error that says “Windows could not complete the installation. To install windows on this computer , restart the installation” This message occurs in safe mode, AD restore mode and in last known configuration mode.

enter image description here

How can I get my OS to boot at this point? Do I need to reinstall 2008 R2 from scratch?
