Hyper V windows server replication

I have two windows server 2012 r2. I have setup a hyper v 2008 r2 server and have enabled replication between the two 2012 servers. Replication completes but when I do a test failover the VM will not start and give me a

UNMOUNTABLE_BOOT_VOLUME

any help would be appreciated.

Are you able to export and import the VM on another Hyper-V server and have it boot properly?

I am trying that now. I will let you know when finished
Yes. If I export to another server it does boot correctly
A little history. This was working fine yesterday and I had some issues with the server so I needed to delete the replication and create a new. I made sure I deleted all traces of the old machine
Remove Replication from all VMs on the source.
Delete all VMs on the destination and clean-up any remnants in subfolders.
Recreate the replication relationship.
Ok. I will try that and report back. Thank you.
Did not work. This particular hyper v will just not work. Keep getting the same error

Ok but the same exported VM that boots fine on another will not boot on the replica server.
? Importing the exported VM on the destination server and booting it up gives the error as well?
Strangely yes.
What do the Hyper-V specific logs say on the destination server?

I'd be looking to flatten the destination server and start fresh. Something sounds out of whack there. I suggest using PowerShell to set up both source and destination so that they are virtually identical.
Thank you. I will do that and report back
Thank you. I again did a clean export and import back in and it fixed. Thank you
