Need to reinstall Windows on a Lenovo Y50, no OS CD?

[ThatAngryGnome]

I want to get rid of the crappy 5,400 rpm HDD that came stock with the Lenovo Y50 and upgrade it with this 512 gb SSD. Problem is there is only one HDD spot, and Lenovo doesn't send any CD's with their laptops. How would I go about reinsatlling Windows (8.1) with the same key as the one that came with the Y50? 

 

Thanks for any help. 

 

EDIT: I do have an external HDD USB3.0 enclousre if that could help.

TPB and activate with your key...

I think you can download the ISO file on the Microsoft homepage. Of course youre gonna need the legit serial which should be on a sticker somwhere on your notebook.

Why not get it directly from Microsoft, rather than TPB?

 

Just use your existing key with the setup, create bootable USB and then use that to install http://windows.microsoft.com/en-GB/windows-8/create-reset-refresh-media

Is this something new? Didn't know they offer this. Much better way indeed.

Nope, been able to do it for a long time. Just need an active key and you can download the ISO.

If you can't download it from MS, use this: https://docs.google.com/file/d/0B5mkRoxIcTA2MWl2UkkzMlFYYjA/edit

 

It's the official 8.1 ISO. Your laptop did come with 8.1 right? And not 8?
