Windows 2012 Server fails to boot due to 'inaccessible boot device' after restore to different hardware.


Following a successful restore to different hardware (Restore Anyware), Windows 2012 Server (Domain Controller) fails to boot due to 'inaccessible boot device'.

Error Message

inaccessible boot device



Please note that the following workaround is specific to restoring to a HP ProLiant DL320e G8 server that has a B120i RAID controller.

  1. Boot off the Symantec Recovery Disk (SRD)
  2. Go to Utilities/Load a Driver (provide hpsa2.inf to load the driver so that disks can be seen prior to starting the restore)
  3. Start the Recover My Computer wizard
  4. De-select the 'Use Restore Anyware to recover to different computer' option
  5. De-select the 'Reboot when finished' option
  6. When restore is complete, go to Analyze/Explore My Computer and make a note of the drive letter that is assigned to the restore system (for example. G:)
  7. Go to command prompt and run the following command: Dism /Image:G: /Add-Driver /Driver:"<driverpath>\hpsa2.inf" (replace c:\<driverpath with the location where you have copied the driver to)
  8. Reboot server

This issue is now fixed in SSR 2013 R2. Details here:
