I keep trying to install the Windows 10 Technical preview on my surface pro 2 but it keeps giving me the error "Use the other installation disc that says 64-bit. When you insert it, windows setup will restart"
It gives me an option for x86 and x64....Yep, x86 isn't x64...
I couldn't see a direct link, but if you head for Download Windows 10 Technical Preview - Microsoft Windows that should get you going.
