Hi guys, so my Samsung laptop's hard drive recently failed. I have the option of sending it in for replacement. I was also considering installing an SSD instead. My question is, can I reinstall Windows 8 on the SSD using a key that I already owned for the Windows 8 that was on my old hard drive? I don't see a key anywhere on the machine and of course I can't access it on my old hard drive. Would I have to buy a new copy of windows 8? Thanks for the help guys!
