I have just replaced the harddrive in my laptop and need to re-install windows 7 (no CD)

I have the product key but don't know where to download windows 7 (without wiping out the OS on my desktop)

You may want to download a migration software that can transfer your OS to the new hard drives. I know that if you buy a SSD from them, it comes with an external SATA cable and a migration software that moves everything for you while having both drives connected to your laptop via USB

if old drive is still ok, put it back. Burn the recovery discs (about 4 dvds). Once done, replace the drive and boot from dvd. All laptop owners should burn the recovery dvds as soon they get the laptop. Unfortunately most people don;t do it.

Other option: Laptop should have a MS sticker at the bottom. It has the key code that is attached to the machine. Borrow any windows 7 disc and use the key code. You need need to install all the drivers from laptop manufacturer's website.

Good luck
