My Macbook Pro already dual boots MacOSX or Ubuntu with ReFit. I would like to add Windows 7 in the mix. I can make enough space in the Mac partition to accomodate that, but just want to be sure the Windows installation is not going to wipe out anything and I will still be able to access both OS.

Anything else to watch out for is welcome.

(Sorry for not posting a question about an actual problem, but I figured that when I have a problem, it will just be too late).

Your title references XP and your question references 7. Also, any update? :) – JoshP Sep 27 '12 at 12:33
@Josh, that's pretty old.... I believe I followed the guide from the Ubuntu website, it has all the instructions there. Look for triple boot on Mac. Everything went fine (at the time, I installed Win 7, not sure why I put XP in the title) – Matthieu Sep 27 '12 at 14:05
Thanks for the update. Yeah, I know it's an old question, cheers :) – JoshP Sep 27 '12 at 14:22

I recall seeing this on a while back. I've only ever done the dual-boot with MacOS and Ubuntu, but this guide might be of help if you haven't found it already.

There is also some information here :… . Thanks for the answer, I'll keep my fingers crossed. – Matthieu Jan 14 '11 at 4:32

I triple booted on my Macbook pro with rEFIt between OSx Leopard, Ubuntu 8.04, and Windows XP.

The rEFIt page says it does not support Windows Vista because of firmware issues, and since Windows 7 is based off of Vista, I do not think you will have much luck with it.

Besides, to get my Mac to triple boot was an absolute pain. It required about 3 days of troubleshooting and using windows and Linux rescue disks to fix the master boot record and Grub. I do not recommend it. Do yourself a favor and just run virtual machines.
