I know this is an old thread & have not tried it yet but thought I would just throw it out there Incase someone stumbles upon this tread with the same issue. I was not aware that you could run windows operating system as well as Mac OS on the same Mac.
Dual booting.
The one thing that you want to be aware of when doing this is that the OS you are trying to dual boot (in this case Windows) has drivers for the Mac hardware. Some newer Macs may or may not support certain Windows versions due to drivers (or maybe due to other restrictions as well).
If you spend a lot of time within an OS that isn't the main one, I would personally suggest running a VM of Windows, that way you can run both OSs at the same time. The downside to that is that it does require shared resources, so you want to make sure that the computer you are running this on has enough resources to run both OSs at the same time. This is my actual preferred method when I do have to do something in Windows that either I'm not efficient in doing in Linux or it can't be done (at least to my knowledge, which this reason is getting less and less the issue).
There are a few other reasons why I like running a VM versus a dual boot option, but the main thing is, your enjoyment/efficiency/whatever you want to call it of doing the VM option is going to depend on how well that computer is setup for VMing. If it isn't setup well, then dual booting may be the better choice.
Having both installed and being able to choose which one you want to use. Furthermore the windows OS is supposedly available free with my MacBook. So still allowing the use of window based Winplot.
That's a new one for me. I've never known a non-OEM install of Windows to be free (even the OEM install ones aren't free, as typically it's subsidized through the installation of all the bloat ware on the computer). Well that's not true, if you had Win 7 Pro or higher, you could get a fully licensed copy of XP to run in a VM on that Win 7 machine for free. But not actually hearing of a free fully licensed copy of Windows for a Mac user.
