ERROR: The Boot Camp partition /dev/disk0s3 used by Hard Disk 1 is not supported

  • Parallels Desktop 9 for Mac
  • Parallels Desktop 8 for Mac
  • Parallels Desktop 7 for Mac
  • Parallels Desktop 6 for Mac


I had Parallels Desktop running on my Mac OS X Snow Leopard and was able to run my Windows virtual machine based on a Boot Camp partition without any problem. Then I upgraded to the new Mac OS X to Lion.

Since that time the virtual machine starts with the following error message:

The Boot Camp partition "/dev/disk0s3" used by Hard Disk 1 is not supported. Please open the virtual machine configuration and select a supported Boot Camp partition in the Hard Disk 1 settings. 


The Boot Camp hard disk number on Mac OS X Lion differs from the one you had in Snow Leopard.


Please re-register your Boot Camp partition in the virtual machine configuration:
  1. Open Virtual Machine Configuration by clicking on 'Virtual Machine' menu, choose 'Configure', go to 'Hardware' and select 'Hard Disk 1'.
  2. Remove Hard Disk 1 by pressing the "-" sign and save the changes.
  3. Then add the Hard Disk by pressing the "+" sign and choose your Boot Camp partition hard disk.
  4. Save the changes, close the configuration window and try to start your virtual machine.
NOTE: In case solution above does not help, please contact Parallels Technical Support.
