Symptoms
Consider the following scenario:
-
You have a computer that is running Windows 7 or Windows Server 2008 R2.
-
You enable the Unified Extensible Firmware Interface (UEFI) mode on this computer.
-
Then, one of the following events occurs during the startup process:
-
You press F8 to open the Advanced Boot Options menu, and then you press ESC to cancel.
-
You start the computer from the Windows installation DVD, and then you click the Repair your computer option to start Windows Recovery Environment (WinRE).
-
A recoverable error occurs when Winload.efi or Winresume.efi is loaded, and then Windows Recovery Environment (WinRE) is started.
-
In the scenario, the startup process may hang (stop responding) at a black screen.
Note This issue may be more likely to occur when you have hotfix 980598 installed on the computer.
Cause
This issue occurs because the one of the following applications does not clean up all the page table entries for the pages that were freed:
-
The Windows Operating System Loader (Winload.efi) application
-
The Windows Resume Loader (Winresume.efi) application
When the Bootmgfw.efi application tries to clean up these page table entries, this application accesses an invalid memory address and causes an access violation exception.
Note The Bootmgfw.efi application is the Windows Boot Manager application.
