There is nothing on the Desktop, because it is an account used for the first time.
So you are now signed in with the Admin account in Safe mode. Is that correct?
If yes,
Open a File explorer, choose This PC, and then navigate to this path: C:\Users\DR M\Desktop (of course you won't find DR M, but your user account name). Find FRST tool, copy it and paste it on the Desktop of the Admin account your signed in now. You will need it to run the fix.
