Funny: Windows 7 BSOD and repair giving an “Unknown Bugcheck 50”

Posted by jpluimers on 2014/08/29

Had a funny error on one of my Windows 7 development VMs today: “Unknown Bugcheck: Bugcheck 50

I hadn’t used the VM for about 2 months, and left it in a suspended state. After resuming it got into a BSOD, booting would hang at the Windows logo, and a second boot would get into the Windows Startup Repair.

Startup Repair indicated it could not resolve the issue, offered a “Restore” (which I declined) then told me something like

Root cause found:
Unknown Bugcheck: Bugcheck 50. Parameters = 0xfffff880009aafb8, 0x0, 0xfffff8000347bc60, 0x0.

The solution was very simple:

  1. At the end of the Startup Repair, go to the System Recovery Options
  2. Click on Shutdown
  3. Then reboot the VM
