When converting a Windows XP / Windows 2003 machine with P2V utilities, a STOP: 0x0000007B may occur during boot in Hyper-V. (Pressing F8 during boot and selecting the option to "Disable automatic restart on system failure" will reveal the blue screen error code.) Typically this indicates the lack of a necessary driver required by Hyper-V virtual hardware (IDE channel).
To confirm the issue relates to this article, follow these steps:
- Mount the VHD to examine the contents
- Within the VHD, locate the SYSTEM registry and mount it with RegEdit (\windows\system32\config\system)
- Check the file system and registry for these entries
- Confirm Files Exist
-
- windows\system32\drivers\intelide.sys
- windows\system32\drivers\pciide.sys
- windows\system32\drivers\atapi.sys
- Confirm Registry Entries Exist
- HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\pci#ven_8086&dev_7111
- HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\pci#ven_8086&dev_7110&cc_0601
- HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\primary_ide_channel
- HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\CriticalDeviceDatabase\secondary_ide_channel
- HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\IntelIde
- HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\PCIIde
- HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\atapi
Any missing items from step #3 can be remedied through the information given below. Hyper-V requires these critical devices and services to boot; a lack of this information in Windows will result in a 0x0000007B, or perpetually rebooting machine.
