I just got a new laptop that came preloaded with Windows 10 home. I also replaced the hard drive with an SSD, loaded Windows 7 Ultimate via Daz Loader and ran the upgrade to Windows 10. Instead of upgrading to Windows 10 Pro, it's only upgraded me to Windows 10 Home. Edit: In my BIOS, there is an option to delete a key, I am assuming this is the Windows 10 key... should I do that first? I am wondering, if it detects a key in my BIOS and just ignores what version I am upgrading from.
