TrueNAS restart/boot problem

I have tried installing a number of NAS/file server software recently and TrueNAS is first one that has completed but when I got to the end I tried entering the IP shown from another PC but got ‘page cannot be reached’ then tried some of the other options and none seemed to do anything until I got to ‘restart’ and it appeared to be working but I had forgotten to remove the install media and that restarted so I stopped it straight away but all I am getting now when I try to start PC is mainboard logo and even keys to access BIOS etc., are not working, do I have to go through install again?
