Two days ago i've successfully connect my BootCamp to Parallels 17 (using trial version for now). After this i've successfully updated MacOS to Monterey and installed win11 and since then all gone. Bootcamp hasn't connected to Parallels automatically and manually too. Then i've done this things many times: - Reinstall win10 (different versions) - Reinstall MacOS (to Monterey - Reinstall Parallels to 16.5.1 I found out that when i'm trying to manually use bootcamp as parallels, there is no "Physical Disks" in "Hard disk>Source" in custom install settings window. Typing "vm.bios.efi=0" in Boot Flags also didn't work out. Seems that i'm doing something wrong or it's just Monterey somehow hide my physical disks from parallels (Full Disk Access is given). The best i want is to use Windows 11 in Bootcamp and Parallels both, but i would be happy even with Windows 10.
