Mike wants to know how he can install a Panasonic version of Windows 10 to his hard drive. Leo says that he won't' be able to get a "Panasonic version," but he can get the drivers from Panasonic's website. So use the Windows Media Creation Tool to install Windows 10, and then add those drivers to it. A clean install is the best way to do it. Leo also recommends taking Mike's old drive and get an external enclosure for a USB drive, which makes a nice backup too.
