Hyper-V on W11 Pro - Unable to Start VM (or invoke from 3rd party app) Corruption? Settings?

Flipmode · 2026-06-20T16:11:59-0400

Hi, just wanting to get Hyper-V running and overcome the uphill battle of VMware Workstation on Windows 11 Pro x64 24H2.
I have unisntalled VMware 17, rebooted. However after installing Windows Features: VM, Sandbxo, WSL2, Hyper-V (Mgmt & Tools) - see screenshot, creating a VM and trying to start it, I am getting an error. Will not boot or launch the VM.
See diagnostics and ouput I have performed below. Would appreciate input of a guru, expert or magician.
I will update to 25H2 after resolving issues.
Thanks for your time, Cheers!

When I run "bcdedit | findstr -i vsmlaunch" = blank. Perhaps is the issue? I don't know enough about Hyper-V...

Strange error about not supported on client operating systems??

Nothing since adding roles, VM, etc:

Hi,
What OS did you choose to run as a VM please?

When it came out, I used to have MS Hypervisor running Ubuntu but getting sound can be problematic, so I switched to
VMware many moons ago. I find VMware Workstation more than adequate with Linux distros but I also run multiple Windows VMs.
