My laptop CD drive doesn't work, so there's no way I can use the toshiba recovery disk, not even with a usb dvd drive. So I used my friend's Vista Home Premium DVD (same as what I had on my laptop) to get Vista up and running, but for some reason, the installation wouldn't accept the CD key on the Microsoft sticker on my laptop, and would take the one my friend had. So installed it using his serial and DVD, hoping to be able to change the serial once setup was complete, but it again refused to recognize my laptop's vista home premium key. What should I do? Is there any way to get Vista to install using my own cd key, or do I have to go the pirate route?
