Hi,

I have bought a Inspiron 15R (5521, Late 2012).

My warranty period is over and i did't take up the system restore disk.

Now, i got a problem with my HDD and it did't not start up.

SO, i have replace my HDD with new one..

I did't get the OS CD along with my system ( Microsoft Windows 8.1).

As well, there is no Microsoft product key sticker any where in my laptop.

I have checked it by removing the battery also.

I understand that i have bought a Windows 8 license along with my laptop purchase.

I have to re install OS on my system and i need my product key.

Any help would be appreciated.

Thanks,
