[NTSysADM] Windows 2008 R2 recovery

[CSSU NetAdmin]

A Windows 2008 R2 server boots to the recovery screen.  It is a VM on
Hyper-V and is a domain controller.  The last image of it was taken last
night at about 5:00 pm- close to 17 hours ago.  Is there a risk with
restoring the image?  There is a second DC in the domain- a physical
machine.  We tried running sfc but get a message about a repair pending.
We ran dism to clean up the repair and revert back but it didn't work.  If
we can restore the image, what options do we have?
