external bootable windows

8/8/2020 update

I forgot to read this doc

https://docs.microsoft.com/en-us/windows/deployment/planning/windows-to-go-overview

Windows To Go is removed in Windows 10, version 2004 and later operating systems. The feature does not support feature updates and therefore does not enable you to stay current. It also requires a specific type of USB that is no longer supported by many OEMs.

The better tool is using

1. Download the related installation ISO file from Microsoft and connect the hard drive to your computer.
2. Go to "Control Panel" and find "Windows To Go".
3. Choose the external hard drive and click "Next".
4. Click "Add search location" to search for the ISO file.
5. Select the ISO file to make the external hard drive bootable.
