When I go to add a new virtual machine to protection I find I have issues because it 

Anyone have any idea why this is happening and how to fix this or decipher it.

I'm not sure exactly what you're trying to say the problem is?  It's asking you to select the OS disk (i.e which disk to boot from).  The file names will match local names.

i didnt explain very well in the first instance.

The drive naming on the asr portal bears only a passing relation to the naming of the actual drives. in the absence of any size data i have no idea which drive to choose.

any he lp would be appreciated in understanding what it is doing.

You can check on your hyper-v management server as to which drive is the OS drive.

Another way to check would be to go to the OS and look into the disk management. It will show the different disks and the volumes on it. Check on which disk is your OS volume. Let us say it is disk #3.

Then go to the VM and check its settings. The 3rd disk attached will be your OS disk.

Hope this help.

Unfortunately, we cannot identify your OS disk as we are a host level discovery and replication. So you need to mark it for us so that in Azure it boots up successfully.

Thank you,
