@theyikes Why do you need to reset it to the original installation state repeatedly?
How to do that is in the wiki here https://wiki.fogproject.org/wiki/index.php/Uninstall_FOG (that doc isn’t yet migrated to the new docs site)
I’m not sure why you’re wanting to start the server side fresh though.
The general idea is
Create Fog Server on a linux vm/machine that has enough storage for the OS images (not isos, captures of install states)
Setup a different VM with the OS as ‘golden image’ (With windows you need to utilize sysprep)
Register that VM as a host in FOG and capture the image.
Deploy the image to as many other hosts as you desire
