Hyper-V VHDX disks can be created from a physical computer with Disk2VHD. You will end up with a VHDX disk. If you run into a problem where you cannot run Hyper-V, VirtualBox is a good alternative. The roadblock you might run into is that VirtualBox cannot run VHDX files. To convert to VirtualBox VDI Disk (VirtualBox native format):

• -click START > RUN
• -type: cmd
• -inside the command window, type: cd c:\program files\oracle\VirtualBox\
• -hit enter
• -type: VBoxManage clonemedium disk c:\path-to-vhdx\DESKTOP.VHDX c:\path-to-vdi\DESKTOP.VDI --format VDI

Now simply create a VM and use/attach the VDI disk.
(In the settins, I had to checkmark "Enable I/O APIC")

Bonus

Let's say you want to start the VM without a GUI. This is "headless". If you want the VM to start when the host starts:

• -click START > RUN
• -type: cmd
• -inside the command window, type: cd c:\program files\oracle\VirtualBox\
• -hit enter
• -type: VBoxManage list vms
  (this will show a list of VM's)

Let's add the VM to start automatically on a Windows host:

• -click START > RUN
• -type: shell:startup
• -create a shortcut in this directory
• VBoxManage startvm MyVM --type headless
