I recently got a new internal hard drive for my laptop and I was wondering how I can install windows 8 onto it. My old hard drive broke and I (stupidly) didn't make a backup or recovery disc. The new hard drive is a Toshiba MQ01ABD100. My laptop with the old hard drive came preinstalled with windows 8 so I think the product key is embedded into BIOS. I'm wondering if I have to order a new copy of windows 8 or if I can download it online and make a disc. I ordered a recovery usb drive from toshiba, but that didn't work either. Also, I think if I bought a new copy it would be a retail version and not an OEM version of windows 8. Anyway, I'm not really sure what to do and this has been going on for almost 2 months now. Thanks!
