You can further information on the recovery environment here: Recovery options in Windows 10 - Windows Help I just reread your post as well as the other thread you created (??) Your running windows 10? Did you check your machine was compatible? If you have Windows 8.1 on a usb then you could always re-install that although you'll need a activation key. However if your already using windows 10 then you may have lost the chance to use the jellybean key finder as you have already removed your original os. Did you upgrade to Windows 10 or perform a clean install?
