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.

  • You try to start the computer from a Windows Preinstallation Environment (Windows PE)-based RAM disk image. For example, you select the Repair your computer option to restore the computer at startup after you press F8, or, you attempt to boot Windows PE from a USB Flash Drive.

In this scenario, the boot loader cannot load the operating system. Additionally, you receive one of the following error messages:

The boot selection failed because a required device is inaccessible (c0000225).



*** Fatal Error 0x00000001:
(parameter1, parameter2, parameter3, parameter4)

Note The parameters in this error message vary, depending on the configuration of the computer.

Windows Boot Manager

Windows failed to start. A recent hardware or software might be the cause.
To fix the problem:  

1. Insert your Windows installation disc and restart your computer.  

2. Choose your language settings, and then click "Next.  

3. Click "Repair your computer.

Status:0xC0000017

Info: An unexpected error has occurred

Cause

This issue occurs because the status of the allocated memory is out of synchronization between the memory manager that is used by the UEFI and the memory manager that is used by the boot loader.

Some memory that is used by one of the memory managers is still marked as available by the other memory manager. Therefore, the issue that is described in the "Symptoms" section occurs.
