we have a new Hyper-V Virtual Machine running SBS 2011 and discovered serious issues with the OS partition file system. A chkdsk in read mode shows this:
The first NTFS boot sector is unreadable and corrupt. Reading second NTFS boot sector instead.
Scan finds several index errors.
When restarting the VM to run chkdsk in Fix mode the OS partition is empty. There is nothing to boot from. We restored a previous snapshot so the VM is running for now.
Is there a way to recover from this? Can the OS partition be repaired? This is a live server and currently in use.
Any help would be appreciated.

Do you have any events related to the error in app/sys logs?
You can try to run low level repair.
