windows 7 product key info

[AMDPOWERED]

i recently bought a laptop with windows 7 on it,it didnt come with an os disk but it does have a windows 7 home premium product key on the bottom of it.i want to install a bigger harddrive in so it would require a full reload,can i buy a windows 7 home premium disk and use it to reload it using the product key thats on the bottom of the laptop then use the product key that came with the new disk to load my desktop?this may have been asked before but cant find it.thanks for any help!

Just download your Windows 7 ISO from here http://www.mydigitallife.info/downl...cial-32-bit-and-64-bit-direct-download-links/ burn the ISO to a DVD, then install the OS using the product key on the bottom of your laptop.

Should work, and it doesn't cost you any money and it's legal.
