So here's the deal. My laptop came with a genuine copy of Windows 7 Home Basic 64bit but the harddisk recently got a problem so I had to replace it. I installed Windows 8 Release Preview 32 bit afterwards and since its gonna expire in January id like to purchase the final build/product. Question is, will I be eligible for the $40 upgrade plan considering I have a new harddisk?. I still have the product key of my previous version of windows written under my laptop, I don't know if that helps. Plus my laptop didn't come with a recovery disk as the recovery was included in a partition of the old harddisk. Thanks.
