Now I will mainly introduce how to install Win 10. For Win 10 is originally support UEFI, it's easy to install. First you should prepare Win 10 ISO file. Here I recommend Windows official original edition.


1.Install UltraISO, then open software. UltraISO is a really good Hard drive / USB drive read-write device. If you like it or you want to use it for business, I recommend you to buy a licensed one. Find and open the already downloaded Windows 10 64-bit system file then run it. After running this file, you can find many IOS files, use it directly.
