OEM Windows 8 on new SSD?

My Windows 8 laptop came with Windows 8.0 preinstalled along with Lenovo's bloatware. I assume the licence key is embedded in the BIOS. There was no option to create recovery disks, and now the hard drive crashed so I bought a blank SSD. How can I get a legit version of Windows 8 onto my new SSD?

I was trying to find a W8.0 iso to install but it looks like there aren't any around unlike W7.

Thanks in advance for your reply.
