I got this HP Pavilion 4 years ago, it came Windows 7 pre-installed (it was Home Premium I guess). Its hard drive stopped working, I dumped it and I bought a new PC. The new PC came with no OS installed. I have this Windows serial number under my HP Pavilion. Three questions :
Is it possible to install Windows on my new PC by using the serial number under Pavilion ? Is it legal ?
If it is not possible (or legal) to do the upper one, is it possible to install it on my HP Pavilion if I mount a new hard disk into it ?
How to do it ?
