SYMPTOMS
When you try to restart a Microsoft Windows Preinstallation Environment (Windows PE) 2.0 for Windows Vista system that uses an AMD Barcelona processor and that has the Operating System Capabilities (_OSC) method enabled in the BIOS, the system will continually restart. Additionally, you may receive the following Stop error message on the screen:

STOP: 0x0000007B: (parameter1, parameter2, parameter3, parameter4) INACCESSIBLE_BOOT_DEVICE

Notes
 * The four parameters in the Stop error message vary depending on the computer's configuration.
 * Not all &quot;Stop 0x0000007B&quot; error messages are caused by this problem.



CAUSE
This problem occurs because Windows PE 2.0 for Windows Vista does not support the new AMD Barcelona processor when the _OSC method is enabled.
