Here is the solution that worked for me.
- Use the Media Creation tool to create an ISO file and save it on your desktop.
- Download the Microsoft Windows 7 USB/DVD tool.
- Plug in your flashdrive which is at least 8gb
- Open the Windows USB/DVD Tool and use it to create a bootable version of the ISO file on the USB drive.
- Restart the machine and go to the boot settings by pressing either F2 or F12 (machine dependent).
- Select the USB drive to boot from.
I did this and was able to switch a laptop from using Windows 10 Enterprise to Windows 10 Pro.
