hey, im kinda new to this site, been lurking and decided to sign up. im not completly computer dumb, i know my way around ok.. but i do have a few questions about installing Win 7 on my One. i have a One D250 and i would like to try Win7, not exactly sure if this computer will hold it tho... 160gig HDD 1.2Ghz processer ( i think) 1 gig ram Been reading u have to have a USB drive to install this? is this true? or can u just download, mount with powerISO and install? or could i put it on my EHDD and install from there? Any issues with things not working? IE: wifi, usb ports etc...? thanks alot guys.. im sure this as been gone over, and im sorry if i asked repeated questions.
