Have to reinstall windows but...

Recently my hard drive became corrupt and i had to change my hard drive. I now have no operating system on. So usually you would just put the Windows 7 disc in and boot from it as your would have no windows, but i downloaded it on the student offer and my copy is not an ISO bootable copy so when i burn my: Setup1.box, Setup2.box & expandedSetup files to a disc i cannot boot from them and thus have no way of installing an operating system. Surely microsoft must have thought of this. It would greatly appreciate some help on this matter. Thankyou
