Suggest me an OS for 2nd hdd

[Beautiful]

I doubt you'd want it but for my netbook I'm putting two OS's on it one for school work called "Edubuntu" It seems pretty sweet to have, and I'm positive my school would approve.

hmm just used google and i found something, http://www.youtube.com/watch?v=2jLlClH8jJ4

this is this is mackintosh os ( for example leopard ) but it runs on a pc? that is why it is hackintosh?

btw is this better then linux?

sory for noob questions all i ever used in win xp and win 7

Hackintosh is pretty much the Mac OSX for windows, it has alot of compatibility errors and it can be complicated to set up, but if your up for it it would be pretty much a mac. And It depends on personal style, one can't simply be 'better'. But what I've seen from macs personally there sweet.
