Yikes! I did find the Upper Filters key blank. Deleted the key and after reboot USB remained inop.
Now, for the oops part. Before finding out what your second option was I jumped the gun. Noticed I did have a restore point (last one in list) created at the time of initial install of VirtualBox. Hastily I decided there was little of importance modified since then (other than OS updates) so I ran the restore. Well, upon reboot she just hangs at black screen after loading bios.
I'm typing this from the other bootable partition of the same comp. I'll be MIA for a bit as I get this new "bump" sorted.
