    Hi,

    With Parallels 17.1.2 and macOS Monterey, I can no longer run Windows from external hard drive.
    I get message that "Operating system not found". With Windows PC, booting from the same hard drives works perfect.
    Full Access is enabled for Parallels.

    How to troubleshoot the issue?

    I can boot from external drive using nested virtualization, running Hyper-V virtual machine inside Parallels.
    It's strange that I can't boot from Parallels directly

    @GampaA@Parallels the article is about running VM from .pvm file from external hard drive.
    I have a different case with external hard drive with installed Windows. I can boot from this drive using Windows PC so there're no issues with drive or Windows. However, when I create Parallels VM and try to boot from external drive, it doesn't work.
