If you have installed Windows on virtual hard disk, you can copy this VHD to another machine and add it to boot menu.
This can be made with the following steps:
- just double-click on it and the disk will be automatically (works on Windows 8.1 and Windows Server 2012);
- if the first method does not work, open Command prompt and run commands:
select vdisk file=D:\win81.vhd
select volume #
You can choose any free disk letter to assign for your VHD, not only Z.
2.Add entry to boot menu.
Open Command prompt, if it was not opened before, and run commands:
3.Optionally reboot the operating system and you will see a new entry in boot menu.
Now you can select this OS and run it!
