Easy dual/triple boot

How to dual boot (or even triple) boot JaS OS X 10.4.7 with windows or linux?

  • If your primary partition is Linux, or you have linux installed:

You should install grub (linux bootloader) at the MBR.

Then add the following lines into menu.lst assuming that you installed OS X on your first harddisk on the second partition (hd0,1):

title JaS 10.4.7
rootnoverify (hd0,1)
makeactive
chainloader --force +1
boot

If you installed on third partition, you should replace (hd0,1) by (hd0,2)

  • If you primary partition is windows, its still possible to use this method!!!

Download and install: http://grub4dos.sourceforge.net/
Follow this examples: http://grub4dos.sourceforge.net/wingrub_examples.html
Use the same menu.lst config as above.

I’m actually using this method as chain0 never worked for me.
