installing Windows 10 Home using usb from Amazon

hi folks,

I am planning a new build and want to install Windows using a USB from Amazon. My question is will it already be uefi formatted? I've searched but have come up blank. If it isn't, should I purchase the product key instead, download the ISO file from Windows and the copy to my own usb stick which I can format to uefi?

My planned build is:
i7 6770K
Gigabyte Z170x Gaming 5
GTX 1080
HyperX Fury 2133mhz 16gb
Samsung 950 Pro m.2 SSD nvme 256 gb (boot drive)
SanDisk SSD 960gb (storage)

Thanks for any help.

Yes, it should work with UEFI. It will come with a product key anyway which you can use with your own USB installation drives, for example if you make a new one when the next major build upgrade comes out (in July).

thanks for the speedy reply :)
