This tutorial will show you how to create a portable Windows 11/10, mainly including the following aspects:
I'm a college student and I use Linux most of the time, but sometimes I have to use Windows, because there are some professional software that doesn't support Linux. I have Linux and Windows 10 installed on my laptop, over time, the free space on the disk becomes less and less. So I'm going to remove Windows 10 from my internal disk and then install it on an external hard disk. I know how to install Linux to an USB drive as live Linux with open source tools, but I don't know how to install Windows 10 to an external hard disk. When I tried to install Windows 10 to an external hard disk, I got the error "Windows cannot be installed to this disk.". Can someone tell me how to create a portable Windows 10 USB drive? Thanks.
