I have Win 7 installed on my main HDD. If I purchase the 40$ Windows 8 upgrade, can I install Windows 8 on a separate partition of the same HDD while keeping the Win 7 partition available (and untouched) through a dual boot option? If so, can I rely on the Windows 8 setup application to take care of installing the boot loader and adding the two OSes to the boot options? Or is it something that I have to take care myself with some third-party boot loader and custom installation steps? In other words, I want to end up with a dual boot setup made of Win 7 and a new, freshly installed, Windows 8 setup. Is it something that I can do with the "upgrade" Windows 8 license? Thanks, Ozo.
