all of my vm's won't boot, i have tried reinstalling. i didn't change any settings BOIS or otherwise. they all just get stuck on a black screen with a flashing cursor. i really don't know what to do.

the attached log is for ubuntu server 20.04, first boot.

Thanks for any help

00:00:12.786512 NEM: WHvCapabilityCodeHypervisorPresent is TRUE, so this might work...

Hyper-v is present, so most likely a Hyper-v conflict. Ditch ditch ditch...

See last post in FAQ: I have a 64bit host, but can't install 64bit guests.

thanks, it was that Linux subsystems were enabled. i didn't know that was an issue.

Thanks for reporting back.
