@car, you cant install from usb right? yes you can, the Point is to know how to boot from usb. the Jumper ezpad 5s Needs from bios a bootmedium with efi configuration. i downloaded a Windows 10 x64 pro iso und the tiny tool rufus 2.8 i guess. then you have to config the usb drive with uefi and fat32 (of Course you can take the home Version to :-). please forgive me my bad english im am from Germany.
have fun 🙂
