Windows 10 Recovery options
If you upgraded to Windows 10 using the media creation tool you have the option to use it to create install media either on a disc or a USB flash drive. Even if you waited for Windows 10 to be delivered in the background you can still download and use the tool after you’ve installed the OS, and you can create media for use on other machines too.
Need A blank USB or DVD (and DVD burner) with at least 4 GB of space if you want to create media.
