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?
You need to add the TPM in the section for hardware in the VMs settings. There's a plus / minus sign at the bottom.
When I click the plus / minus sign under the VM's hardware settings, I see that I can add a... • Network • Printer • Hard Disk • CD / DVD • Serial Port I don't see anything about adding a TPM, or have any sense that a TPM would be a subtype of any of the above. Can you be more explicit?
If you go to Hardware > + on your Mac with an Intel processor, but a TPM chip isn't there, it might be caused by the fact your Windows virtual machine is based on Legacy BIOS. TPM chip will work with UEFI/EFI BIOS only. 0. Check if your virtual machine has Legacy BIOS by following the steps from KB 115815. If Legacy is set, create a new Windows virtual machine. When you get to the Name and Location window when creating a machine, enable Customize settings before installation. In the automatically opened configuration window go to Hardware, click + > select TPM chip > Add. Close the configuration window and proceed with Windows installation.
Yeesh, Parallels doesn't make it easy to create a new VM and supply the virtual HD later... but OK, I told it to skip actual installation, but that it would be a Windows 10 box, and to Customize the settings. Went to hardware. Under Parallels 13 there's nothing about adding a TPM chip. About to remote into my newer computer and try the same under Parallels 18...
OK, Parallels 18 let me create a new virtual Window 11 machine without a hard drive. It has the TPM chip. I will duplicate my Windows 10 HD and use it as the baseline for downloading Windows 11.
If it helps in any way, I made a Win11 install (full install) on Parallels v17 (w/ TPM), copied the VM to my Parallels v16 machine and it ran just fine even though you couldn't add a TPM using v16 as I guess it accepted what was already there (bypassing the Windows complaint).
I tried booting my blank-HD-generated Windows 11 environment using a copy of my Windows 10 64-bit HD. It won't boot ?!? This strategy has always worked before when any OS has an upgrade and I wanted to preserve the old OS as well as acquire the new. Next attempt: see if I can use a Windows cloning utility to move the contents of Windows 10 over on top of Windows 11 after creating it, and THEN run the Windows11InstallationAssistant. This would be a lot easier if I could just add the TPM to a copy of my Windows 10 virtual machine
