purchasing games on disks

[ryan123hanna]

probably a stupid question but im new to pc games

if i buy a game such as ARMA 2 on disk will it install onto my hardrive once i insert it or will it ask to insert the disk every time i want to play it and then i will be forced to spin up my noisy disk drive?

i would download it off steam but it more expensive and takes years.

thanks
