Hi Quest. I'm Greg, an installation specialist, 10 years awarded Windows MVP, and Volunteer Moderator, here to help you.
If you go into WIndows Settings > Apps > Apps & Features > scroll down to Programs & Features > Turn Windows Features On & Off. In the box that opens you should see Hyper-V, check the box besides it and Apply. Close box, restart PC.
If it's not in the box then go back to Settings > Apps > Apps & Features > Optional Features to see if Hyper V is in the list to install.
If not then check in the BIOS for any settings to enable Virtualization.
If you cannot find these settings anywhere then your PC does not Support virtualization. If you are in doubt about this, contact the manufacturer's Support, or report back here the make/model so I can research the model further.
I hope this helps. Based on the results you report back I may have other suggestions if necessary. If you will wait to choose whether the problem is resolved, then I will continue to help until the problem is fixed.
