Can I reinstall Windows 7 using a different install CD?

DPaid · Sep 15, 2014

Hi everyone!

I recently bought a Samsung SSD 840 EVO (250GB) and I would like to perform a clean install. However the problem is I cannot find my Windows 7 disc to save my life. Luckily one of my friends who has an unused Windows 7 disc is willing to hand it over so I can perform the clean install onto SSD.

My question is am I able to install Windows 7 again even though it is through a different CD with a different key, and will there be any conflicting problems between the Windows 7 installed on my harddrive (which I plan to wipe) and the Windows 7 that I will be installing on my SSD?

Thanks for the help!

You can install from any Windows 7 DVD that is the same version(I would guess you had an OEM one) without issues. It will ask you for the COA number and you just need to use the one from your current system.

You can also download an ISO to burn your own if you wish.

Sorry I forgot to add that in. Yes, the Windows 7 edition I have and my friend has are both Ultimate.

Also what is wrong with using the key on the disc he owns?

One product key = one computer. If the product key is already in use, you can't use again. You can use your product key with any installation image as long as the versions match.

Oh alright. However, the Windows 7 disc has not been used. My friend told me he has not used it since it was a spare for a computer but decided to just get Windows 8.

Why would you waste a key that can be used on another system if you already have one for that system?

As long as it is only one system, it is legally fine, but kind of a waste since you will have 2 copies of windows locked to that single system.

Your current system/motherboard already has a valid key? Why use a different one?

True, you do have a point. I guess I will just use my key.

Since the key is not on the DVD anyway, your current key should work with ANY DVD of the right version. I always use the same DVD for installs(even made up a flash drive for installing), just a different key per system.
