Pc won't start after enabling virtualisation

Hi all,

My Precision 7560 won't start once I enabled bios virtualization.

I needed to enable Bios virtualization for some labs on VMware. The one I enabled is the third I believe in the bios list (not sure what was the name of that option). Once I did, the PC refuses to start.

When pressing the start button, the keyboard light flash... And that's it. The fans don't even start. 

I have Windows 11 installed.

Not sure how to fix that. I really need some help. If any of you would have any tips, I'll be very grateful.

Thanks.

Sincerely.
