My Triple Boot System (XP / 7 / OS-X)

Just thought I'd share how I managed to get to my triple boot system.

1. Install XP first as you normally would on any machine. I found a guide over at eeeuser to be the best for doing this from a USB stick... http://wiki.eeeuser.com/windowsxpusb
2. I then installed Windows 7 using myuusmeow's guide here:- http://aspireoneuser.com/forum/viewtopic.php?f=38&t=9194. The only change to this guide was when using partition magic, I created 3 partitions. Firstly I reduced the current XP partition to 55gb, then created 2 new partitions, one at 55gb and formatted using NTFS (for windows 7) then created the 3rd parition at 50gb and left it unformatted for OS-X.
3. Once I'd installed windows 7, I had a boot menu giving me the option to boot XP or 7 (created by the windows 7 installer)
4. I then followed SbM's excellent guide to install OS-X here:- http://aspireoneuser.com/forum/viewtopic.php?f=14&t=10197

When I installed OS-X the Darwin loader took over and gave me a menu with an option to load Windows XP, Windows 7 or OS-X. The Windows 7 option doesn't work from Darwin but if I choose XP I then get the options presented from option 3 above.

I think the last step may be to use EasyBCD to use the windows 7 boot loader to get a nice clean menu for all 3 OS's although I can't get this working properly yet. When I do I'll let you know.

 

but remember guys, first thing first, all partitions must be "PRIMARY" not extended not logical otherwise, it will be screw up.
save partitions to NTFS for windows XP, Windows 7, Linux Ubuntu, and FAT32 for OS X.
good luck.
