Linux does not require windows 7 at all. If you want to dual boot windows and linux then you will still need to fix your windows installation.
You need to get an appropriate windows 7 disc / ISO for your key. Where did your windows 7 product key come from? Was it a boxed product, OEM on the side of the machine?
The alternative is to activate over the phone with Microsoft. Advise them you have a valid windows 7 key, however don't have the correct disc. They will be able to confirm the product key is genuine or not, whether or not they will give you an activation code to work with your ISO I do not know.
i guys i have this Pc lenovo that i installed an ISO of win7 but it doesn't accept the key # that is on the lable on the box.
slow down and we can straiten this out.
Ask yourself one question. What do I want to do with the computer? Does it require Netflix, or computer games (real games, not internet ones)?
If no to the above, then you can install linux without windows. Just download either Mint or Ubuntu, burn them to a CD/DVD/USB key and boot to it. Choose install and follow the instructions. When it ask you what to do with the disk, choose wipe disk and install. Finish teh process and you now have a Linux only machine.
The key has to match the version of windows 7 you are installing. So if windows home premium was installed on the lenovo from the factory with the key then you have to install the same version. You can't install ultimate or pro with the same key. If you need a copy of the correct version, then let us know.
You will need the key on the bottom and a windows 7 pro OEM disk to get it to work. It has to be OEM or it will not accept the key.
I have used the mydigitallife iso files and have activated OEM keys with no issue.

Let me ask a different question here.
The key on the sticker lists what operating system? If its not windows 7 then that key is useless.
