BMR Restore from internal HDD for server 2012 r2 System Restore does not recognise volume GUID

Our Server 2012 r2, a DC uses WSBackup to create a BMR daily backup on an internal drive. The drive is not mounted with a letter but recognised with its GUID \\?\Volume{####-####}
The o/s suffered a catastrophic failure of AD and despite using the server GUI for restore it failed and could not boot out of local account.
The backup disk has 14+ days of potential restore dates.
The o/s disk is a Samsung SSD
We are trying to restore the system but failing to do so completely
The server 2012 o/s is loaded to pre-install from the original disk and to to cmd.
Wbadmin does not list recovery points using syntax Get Versions -backupTarget:\\?\Volume{####-####} Only after the disk is assigned a letter can that information be retrieved.
Using MountVol lists all the disks and the backup is returned as \\?\Volume{####-####} unmounted

I seem to be missing how to use the Volume GUID correctly in these commands and perhaps also how to mount the drive whilst in Pre-install

In attempts to recover the installation of 2012 o/s a fresh install was created partitioning the drive into C: plus 2 other partitions which also seem to have individual GUID's

This may be basic and simple for those familiar using the GUID and how to use Recovery, SysRestore or WBADMIN generally but I have now spent 12 hours trying to achieve what I believed was the most essential recovery; a system crash. All I need is to restore a complete drive by BMR.

OK, Persistence does pay off and attention to some detail including spelling
The restore has to be done using Wbadmin using the volume GUID

The commands are essentially per
https://social.msdn.microsoft.com/Forums/en-US/fa5b51fa-9e65-4121-b0bf-db5d1a15b620/sbs2008-standard-complete-pc-restore-failed-with-0x80070495?forum=windowsbackup

However use
wbadmin start sysrecovery -version:25/03/2021-08:34 -backupTarget:\\?{####-####....#####} -Recreatedisks

NB Use your own version date and time and \\?{Disk ID}

The version can be got from Wbadmin get versions -backupTarget:\\?{####-####....#####}
and the Volume ID from MountVol.exe

Spelling of the commands was incorrect and I should have paid more attention to the full help the Wbadmin screen output.

Hi DSPatrick
This was the first thought to restore the system disk.
However, it returns an error "The volume ID could not be found (0x80070495)"
Closing returns to 'Choose and Option'
