Hi Wira,
Thx for your reply.
* i already have a HDD with W7 in it, it was what i was running b4 the hack. So, as you say that i can boot from 2 different HDD, then, i can just connect the HDD which has W7 in it and boot...right ?
* regarding the GC, the hack which i installed does not have any setting for resolution or a 2nd monitor, it only has a single option and the current resolution is not a perfect fit. So, i assumed that i need to further tweak the GC.
* if i dont have to install any further kexts, then how do i change the resolution and 2nd monitor settings...
Please reply. Thank you.

1) On multiboot, yes, that is correct.
2) On mavericks, yes, there is no setting on the resolution etc. It is either best for display or scaled. Which port are you connecting your monitor to? Is it the internal GC?
3) I believe if you've your monitors connected to both, then the option for the 2nd monitor will be there. Just share here your "About this Mac" -> System Report and under Graphics/Displays. What gets recognised there.
ps: Please don't call your installation a hack, it is quite confusing, just call it whatever OS release you've, if it is mavericks, just call it mavericks etc.
