Sometimes when restoring a backup using image based backup software you may not be able to 'see' the internal hard drive because it been setup by the manufacturer in a special mode (convenient for them but not so much for you).

If you need to restore a backup form another PC you may need to change the disk mode

Changing the disk mode from RAID to 'standard':

  1. Startup the PC and immediately start pressing the BIOS access button, this may be F2, DEL, F10, or F12 depending on the PC
  2. Once you are in the BIOS locate the storage settings
  3. Change the disk mode (as per the image below, change from [1] - RAID to [2] - AHCI)
  4. Restart the PC and try the restore process again
