My laptops hard drive crashed and it had Win7 preinstalled when I first bought it. If I buy a new drive and plug it in will I need to purchase windows again or will it auto install Win7 on the new drive? I don't want to buy windows if I can just use the preinstalled Win7. Sounds stupid.

Just an FYI. In the bios settings it says factory installed OS is Win7, not sure if that changes anything.

Welcome to Tom's Hardware, @Mythrilguy!

The operating system is tied to the motherboard of the computer/laptop. This basically means that a hard drive is just a carrier for the system files. If you plan to upgrade your primary storage, you won't need a new genuine operating system. Since it was pre-installed, it should automatically get activated once you clean install the same OS version onto the new system drive & go online. You can follow the MS instructions on this, if you don't have the original Windows 7 installation media. Either way, make sure you backup all important files somewhere off-site beforehand. The fresh install of the OS will format the drive and erase all other personal data.

Hope this helps. Let me...
