Resolved How to Dual Boot Win 7 after Win 10

I found it quite easy. So to debunk the myth that you can't have dual boot 7 after 10 is nonsense.
First you need to be sure you have a valid copy of Windows 7 with a valid key. I would NOT recommend a Restore disc as this disc will probably overwrite your first rive.
Second you need to allocate a second partition for the installation.
Third open Elevated Command Prompt and create a boot menu by typing in "bcdedit" hit Enter then "bcdboot %windir%" hit Enter without the quotes. Exit then reboot and you will see your new boot menu.
Fourth and finally insert your Win 7 disc and be sure to select Custom Install then select the new drive that you created for the install.
Easypeasy. yes it works, have fun!
