Restoring corebox 5th to factory settings

I recently had a problem with my corebox 5th, it appears that my windows install is somehow corrupted

I am trying to restore it to factory, but it endlessly keeps booting up asking me to install windows, and does not boot.

Is there a procedure to restore it to the state it was when I received it ? ( factory state)

Send me your serial number and i will send you the original files so you can install again
