r00t4rd3d Posted March 24, 2008 Share Posted March 24, 2008 Ok , where to start ..... My goal here is to be able to dual boot between XP and OSX with one hard drive. I started by downloading the "KALYWAY LEOPARD 10 5 1 intel SSE2 and SSE3" DVD install disk. Next I used partition magic to resize my hardrive and create a new partition for the OSX install , XP was already installed. Went threw the setup process , booted off DVD , installed Leopard on new partition. Everything went ok then I rebooted and ended up at a "b0 error" no XP or Leopard , so I did some searching and found that I could boot into the Leopard harddrive install by booting from the dvd image and letting it time out. Leopard works fine this way , loads right up everything works , sound, network ,etc. So I did some more searching and ended up booting off the dvd again , get to a term and running fdisk to set my Leopard partition as active : fdisk -e /dev/rdisk0 print flag 2 ( I choose my Leopard partition) quit y reboot Now when the system starts up it stops at a blinking cursor. The time out method still works for booting Leopard. Only way I can get XP to load is by booting from Partition Magic boot cd and setting my XP partition as active then XP boots fine. But if I want to go back to Leopard , I gotta start the dvd install , get to a term and do the fdisk all over again setting flag 2 to get my leopard partition install active and loading with the timeout method. BLA. How can I fix this without using a hammer ? Thanks ! Link to comment https://www.insanelymac.com/forum/topic/95373-booting-problems/ Share on other sites More sharing options...
Tin_man_0 Posted March 24, 2008 Share Posted March 24, 2008 you should be able to boot mac by using the chain0 method.... copy the chain0 file from the mac disk and add it to the boot.ini file, if you google "chain0" you'll get setp by step instructions.

r00t4rd3d Posted March 24, 2008 Author Share Posted March 24, 2008 "does the rd=disk#s# not boot the mac?" Umm where I enter that ? Right now Im at booting into XP. I have chain0 in C:\ and C:\chain0="Mac OS X86" in my boot.ini , but when I select it on boot I get the HFS+ Partition Error. I checked out that link above and it didn't help me any. I looked at my partition table with ptedit and my Leopard partition type is set to "Extended X" (0F) boot type is 00. I tried setting type to AF , even though that wasn't in the list and setting boot type to 80. Still HFS+ Partition Error.

Tin_man_0 Posted March 25, 2008 Share Posted March 25, 2008 try this.... Leave the XP patition as bootable. Boot of the Mac Disk, and press f8.... at the prombt type rd=disk#s# (replace the # with your hdd# and patition#) usually disk0s2 will do it. and see if it boots the mac.
