After you upgrade from Windows Server 2008 to Windows Server 2008 R2, you may experience one of the following symptoms:
- You receive the following Stop error message on the first restart of the upgraded system:STOP 0x0000007B Inaccessible Boot Device
- Your computer repeatedly restarts. A similar restart issue is described in the following KB article:952942 Installation of Windows Server 2008 on an iSCSI target fails to complete and the computer restarts repeatedly
This issue occurs because the drivers that are in the System device-setup class are not migrated as part of the upgrade process. Therefore, the upgraded computer does not have the required driver loaded.
A fresh install of Windows Server 2008 R2 is required if you want to use the following drivers.
For all x64-based versions of Windows Server 2008 R2 or of Windows 7
For all x86-based versions of Windows Server 2008 R2 or of Windows 7
For all IA-64-based versions of Windows Server 2008 R2
