Spec: Generic VM stuff on ESXi 6.5. Pretty sure it is mirrored boot drives but no way to check now. And one drive for "data".
Logs: uh how do I get those?
History: Test VM to see what is new in SCALE, it pretty much gets updated sometime to see what is new, so it's very barebone with nothing going on in form of usage.
So something in the update broke the bootloader.
