SOLVED Parallels Unable to start the virtual machine

[kaoz]

Hi, first of all i apologize is this is not the correct forum where i should post my issue, but is the only one where i found with search the words "Parallels desktop".

I have my win11 vm from monterey, and i tried to use on ventura installing parallels desktop 19, but when i try to run, it says:
"Unable to start the virtual machine", i tried also to make new VM on other drive even on HDD but i always receive same error, i tried in custom config of parallels "Hypervisor Parallels" instead Apple, but nothing works... i searched on google and forums everywhere but i don't know where is the issue.
I don't know if there something i should change in opencore config, or Bios (Intel VMX for virtualization is enabled).
I really hope someone found a workaround for that.
Thanks

First of all the question is when you have bare metal hardware and Windows is supported on it, what's the reason to go with virtualization?

i have on my hackintosh an nvme with win11, but since i have already a VM that i used in monterey with macpro... i would like to use again in my ventura too (sometimes) i need to use without boot in win11..

no way to fix?

You'll need to configure the Virtual Machine correctly.

Sorry maybe i wasn't clear with the issue.. i perfectly know how to make the virtual machine to install etc.. the problem is the error gives me when i try to start every VM even the one made like in this video .. if you look my screenshots .. u can see that wheni click start on any VM ... it gives me that error..

That's the issue. Delete your VMs, remove Parallels and then follow as shown in the guide. If the problem persists, the host system has problems with its EFI.
