Windows won't boot even in safe mode

It says:

Error

The product key you've entered appears to be for software which was pre-installed by the device manufacturer. Please contact the device manufacturer for software recovery options.

Remind me how you got the key - with a keyfinder program ?? - If yes, then you are dealing with a generic key that has been used for thousands of systems and is useless for you.

No, it is written on the back of my laptop

Hmm, then the only other cause of the message I can think of is that you try to install a version that does not exactly correspond to the key. Else it should work.

Have you owned this laptop since new or did you buy it second hand? What version of Windows 7 is your COA sticker for?

Yes, I owned the laptop since new.
It says Windows 7 Home Prem OA.

The recovery partition also does not work (freezes).
