No worries, VMware or some of the other virtualization software’s should work in this case as most other comments pointed out. Probably the most simple and straight to the point.

If you have the urge to tinker, another potential item or route you can look at is a proxmox machine. You can run multiple VMs in tandem at the same time. This would run on a standalone machine.

You would then be able to remote desktop into any virtualized OS on your home network. You can use a software like parsec which I like to access each machine from a clean interface.

I run a Hackintosh’s dual booting Mac OS and Windows. So you solution is not insane as some have pointed out.

What I would suggest is maybe running a NAS on your local network to act as your share. Obviously this won’t help if you dont store your working files on your NAS, but its an idea. I know no way to directly share between the two machines as they are technically not on at the same time.
