I downloaded Windows11InstallationAssistant and ran it, in my existing Windows 10 (64-bit) virtual machine. First thing it did was install a HealthCheck app which promptly told me there were these issues which would prevent Windows 11 from being installed: • This PC must support Secure Boot • TPM 2.9 must be supported and enabled on this PC • The processor isn't currently supported for Windows 11 The first two had links "more about..." and under both links I was advised to go to Settinghs > Update & Security > Recover > Restart Now (under Advanced startup); and on the next screen, to select UEFI Firmware Settings and do stuff. I don't have any panel named UEFI Firmware Settings. I only have "Startup Repair", "Startup Settings", "Uninstall Updates", "System Restore", "Command Prompt", and "System Image Recovery". I poked into "Startup Settings which had yet another submenu of options but none of them pertained to UEFI Firmware. I'm in Parallels 18 (not "Pro", just the plain-vanilla variety). I see that other people are using Windows 11 under Parallels. What am I missing?
