Cannot create a new BootCamp based virtual machine or launch the existing one after macOS 10.13 upgrade.


Improper disk GUID.


NOTE: Parallels Desktop officially supports Boot Camp installations completed via Boot Camp Assistant only. Custom Boot Camp configurations using 3rd-party applications are not supported for virtual environment.

This issue is fixed in scope of the latest patch (13.1.0-43108) in Parallels Desktop 13

For older Parallels Desktop versions, use the workaround below:

Disable System Integrity Protection (SIP).

  1. Restart the Mac, on Apple logo loading screen press CMD + R to boot into Recovery.

  2. In Recovery, on Mac menu bar locate Utilities menu > open Terminal application.

  3. Type in the commands below one-by-one:

    csrutil disable
  4. Back in a normal mode remove the existing machine or create the new one, depending on the customer's scenario.

  5. Boot macOS into Recovery again and enable SIP back running the following Terminal commands:

    csrutil enable
