NFS install - Restore/Repair SD Card

have been using an NFS install for a while and updated to latest OSMC.
I was messing around the other day and was trying out a USB install to see if it met my needs but it didnt so I need to go back to NFS.
I still have OSMC installed so I just need to redo the SD card for boot.
Is there a way to do it with OSMC without a complete new install?
I no there used to be with Raspbmc.

We don’t have the files at hand (they’re generated by the installer), so you will need to transfer them off an existing installation



Did a fresh NFS install :smile:
