STOP 0x0000007B on P2V Windows 7 upwards

Got a STOP 0x0000007B on booting a VM after you P2V. With automatic reboot on error enabled, it also manifests itself as a Windows Boot Manager error, Status: 0xc0000225, Info: The boot selection failed because a required device is inaccessible.

Good old fashioned mass storage driver issue. The hitch is that drivers are there but not enabled in an effort to improve boot performance. The article on Minasi’s site offers a pretty good explanation for Hyper-V, and the same applies to VMware.

To fix:

  1. Mount the Windows install diskĀ and boot to it.
  2. At the first screen (Language Selection), hit Shift-F10 for a command prompt.
  3. Run Regedit.
  4. Load the system hive from the VM’s disk:
    1. Highlight HKEY_LOCAL_MACHINE
    2. File > Load Hive
    3. Select &lt c: &gt \Windows\System32\config\system (name it something like “asdf”)
  5. Expand HKEY_LOCAL_MACHINE\asdf\ControlSet1\Services\intelide
  6. Change the data for value “Start” from “3” to “0”.
  7. File > Unload Hive.
  8. Exit regedit.
  9. Reboot the VM.
