Mac OSX on External hard drive

I was not entirely sure which category to post this in so apologies if I have got it wrong.

So I would like to duel boot windows 7 and snow leopard + more in the future but I just want windows on my laptops hard drive. So What i'm asking is if I can partition my external hard drive to use around 100gb as mac and then the rest as storage? And how I would go about doing this?

Would I have to use something like MacDrive to make a partition of the hard drive or would I just put the installer onto the external hard drive and then partition from the installation?

I am quite tech savvy so I know what I am doing with windows and some of linux, but mac is a new thing for me so I am not entirely sure what installer to use or how to incorporate iboot etc into it. So a full tutorial would be greatly appreciated.

My other worry is if I could use as a fully functioning storage device afterwards and get it to work on both mac and windows.

Thankyou very much for your help, it is much appreciated.

  1. What make/model of laptop are you using for this question?

    A good source for hackintosh "how to" info is: http://tonymacx86.blogspot.com/

    Here on Tom's other sources can be found here: http://www.tomshardware.com/forum/1137-69-osx86-hackintosh-thread

    If you aren't using a Mac, setting up OS X to run on a PC based rig can be a challenge. What is even more difficult is keeping OS X up to date afterward.

    You can also run OS X in a VM. If you are using a Mac, then Boot Camp is the way to go, but I don't think you can run OS X from an external drive as you are suggesting (nor Windows via Boot Camp on the ext HDD for that matter).

    Please clarify what you are using.
  2. I am using an Acer aspire 5755g with an 15-2450m 2.5GHz and a nvidia GT 630m 1gb.

    I am also not bothered about updating to new versions of OSX, snow leopard is my prefered version, in the unlikely account of a better version that snow leopard then an update may be thought about but that woulnt be for a while.

    I had OS X in VMware but I only have 4gb of ram at the moment so it was really really slow.

    Thanks for the help though, I may consider a duel boot.

    OSX is slow in VMWare no matter what you do

    I wasn't referring to to upgrading from one version of OS X to the next, rather I was referring to the small updates applied (similar to how Windows Update works) within OS X itself. Often, an OS X update will "break" a hackintosh install. The work-arounds to resolve can be complicated.

    Also, setting of a dual boot system with Win 7 as the primary OS and OS X as the secondary is no trivial matter.

    To use OS X "painlessly" you really need to run on a Mac.
