[tobyblackhall]

im building my first gaming pc. the case im using is Fractal design define s and there is no place for an optical drive. the place im getting the os from is out of Usb Windows 10 kits. how else can I install the os. My sister has windows 10 on he laptop. is it possible to make an iso from that then put it on a usb and just buy the windows 10 disc kit and use the product key on there.

i don't understand your question. if you buy win10 from market, it comes in a usb stick(mostly)
else you can always make a bootable usb using your sister's laptop, it's not a big deal.
