The Corona consoles seemed to always have a problem with this. There was a issue known as spinlock. Sometimes it would work, sometimes it wouldn’t. Unfortunately I don’t have a true fix that I know of. You may try to boot it a few more times, some users were reporting success after a few attempts. There may be a fix out there, but if I knew it, I forgot over time.I seem to be having the same problem. Was there a solution to this in the end?
