I have a server, WIndows Server 2012 R2 Foundation, that I logged into via Logmein and noticed it hadn't rebooted in 300+ days. I triggered an update/reboot via Logmein.
For 24 hours it's been in a reboot loop, fir "getting WIndows Ready do not turn off your computer" followed by "Could not update rolling back do not turn off your computer".
The weird part is I can get into the box with Logmein, I can see the dashboard, processes, get a command prompt, etc.
I have tried:
Last known Good Configuration (didn't help)
Create some kind of boot disk with a Windows 12 download?
Boot into safe mode?
