I obtained a free desktop tower with everything in it except for the hdd and recovery hdd. SO there is no real memory. I have cds/dvds/laptop hdd/and usbs, how can I install windows onto one of these devices or any other way? The laptop hdd cannot connect the tower directly I need some stuff to adapt to it.

Note: When I try installing windows I go until the part where it says trying to locate the sata drive (hdd), and I dont have one... Is there a way to make it instal onto the usb and load windows from there everytime i boot up? Thanks.
