How to restore image backup without urserver using restore boot USB

After removing a workstation from service and deleting it from the UR-server I was attempting to reset the windows on that old workstation. It failed the windows reset leaving me with half a windows install. I have a copy of the old UR-server backup files on an external HDD. I was going to try to restore the image using the UR restore boot usb. I was eventually able to get the NTFS drive with the image files mounted after booting from the ur-restore iso installed as a bootable usb.

I found the UR client command line needed to restore the .mbr file from the data drive, but there does not seem to be a urbackuprestore_client program on the USB or at least I can’t find it if it is there. I feel I’m very close to success but I’ve hit a wall at the last step.

After booting from the USB and canceling the UR restore process because it won’t find a ur-server. I then open a terminal, su to root. create a mount and mount the attached Seagate NTFS drive with all the files on it. I then located the folder containing the vhdz files.

But now, how do I tell the system to do the restore from here?

A.I. suggested:
"./urbackup_client --plugin ./liburbackupclient.so --restore --restore_cmd write_mbr --mbr_filename /mnt/seagate/path/to/your/Image_C_vhdz.mbr --out_device /dev/sda
"
however there is no urbackup_client application that it can find.
