I recently used the detailed info in Henk Ps thread to install Windows 10 64 bit on my MB 2,1. So thanks to him I have a largely working Windows 10 installation - more than I expected initially if i'm honest - so thats vm appreciated! But there are some problems, whichI think are possibly related to my uninformed initial choice of 64 bit rather than 32 bit and also possibly of Windows 10 rather than 8.1. So thats where I'd like some thoughts of those more experienced than myself please. For info the issues are mainly; Internal backlight/brightness and external monitor issues Fairly regular trackpad issues where 1 and 2 finger tap stops working until logout/reboot No Sound Though I've put more specifics in Henks thread and can do that here too, as I say I'm firstly trying to establish the 'best' starting point for a low maintenance Windows instal. In case its relevant to the above, I have an SSD boot drive (dual booting 10.7 Lion - no Bootcamp), with a HDD in an 'Optibay' like mount for additional storage and 3G RAM. Like many I suspect, I only use an external screen occasionally for more space and even less often an external keyboard/mouse. So to make use of the Macbook with Windows, I really need a reliable trackpad and internal monitor. Sound would be good too of course, for some background music/occasional video All feedback welcome, even if its of the type 'it'll never work fully', as I then won't invest time in trying to find fixes that don't exist!
