I walked into my office this morning and my secondary workstation (a Windows 7 machine) has a Black Screen of Death and was complaining about unauthorized OS or driver changes:

Press [N] to run the next boot device, or enter directly to BIOS Setup if there are no other boot devices installed.
Go to BIOS Setup > Advanced > Boot and change the current boot device into other secured boot devices.
This sounds bad. Although this machine has 3 hard drives in it, none of the others are boot devices. I'm worried this might be ransomware or something. Or it might just have been that unwanted auto-upgrade to Windows 10 I've been hearing about.
It doesn't really look like I have any real options but to start tinkering with the boot but I'm not even sure that will help.
