Ok Guys i am not sure if anyone has used Windows 8 on dual monitors / even on Dual boot... so I thought I'd Share the screenshot (taken from Galaxy Note)
Once you install Windows 8 on a different Partition, This is how the new Boot Menu to Select any OS appears... You can use your mouse to select it... Now if you choose windows 8 it will continue booting... but if you choose windows 7 it will reboot & boot into windows 7 without giving any options.
Got a 5.9 as its on a 2TB hdd & not on my SSD, the weird part here is that there are 2 taskbar. if you right click on the taskbar on your secondary display it will give you an option to use it as your primary task bar.
the secondary task bar doesn't show any notifications ( time, network etc) Also if you open an application it appears on both the taskbar's
Actually, although have not tried with dual monitors, I do know that it is a feature of W8. Had read it somewhere. Something to do with productivity.
As for the dual boot, seen this in the DP.
