Got my new ssd installed in the deck, booted into recovery and started reimagining. It was going fine for a while then I started to see a lot of errors and it hung for a while.

But after sitting at the above image for a while it started moving again. Now it is stuck again, and for far longer than before. Is it safe to turn it off and go back into recovery?

Update: rebooted and it booted into Steam OS, and is updating.

Update 2: after the reboot and update I am not signed in and installing games.
