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

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.
