Veeoh Posted March 3, 2006 Share Posted March 3, 2006 Hi, I have sucessfully installed Mac OS X 10.4.5 to my AMD 64 system on a second hard drive. I have Windows XP on the first drive. I can still boot into XP so the MBR has not been overwritten but of course this means I can not boot into OS X Are there any guides to show how to use a "Boot Manager" or whatever to allow me to boot into both OS's? I hope so as I really dont want to lose my XP install just yet lol! I have searched the forums and the interweb but can only see the efforts to install XP on an Intel Mac (for some reason..) Anyone help? Cheers!! Mark Link to comment https://www.insanelymac.com/forum/topic/10806-dual-boot/ Share on other sites More sharing options...
R. Bear Helms Posted March 3, 2006 Share Posted March 3, 2006 Quick way is to use a partition utility (xp has a command-line one called diskpart) to set the OS X partition as "active" (usually this should auto-clear active off the XP partition) and boot the install DVD for OS X. Don't type anything and the loader should notice the nice ready OS X partition and boot it. Another thing people do, assuming OS X is on the slave drive and XP is on the Master drive, both on the primary IDE channel, is to get a small file called CHAIN0. There should be a link on the boards somewhere - it's a generic boot the slave drive switching program. You edit C:\boot.ini to have the line added at the bottom: c:\chain0="Mac OS X" This requires the chain0 file be stored in C:\ directory. Then when XP boots, you'll have a menu of Windows XP and Mac OS X.

autoy Posted March 3, 2006 Share Posted March 3, 2006 You can find the boot 0 in the 10.4.3 CD. I'm still using this for dualboot with 10.4.5 and still works fine. Set the XP partition active using diskpart like Bear said, put the chain0 in c:/, modify the boot.ini and your're done. The XP bootloader will take you to the darwin bootloader and there you select the osx partition.

DerAlSem Posted March 3, 2006 Share Posted March 3, 2006 That's definitely won't work in case of two partitions (XP and OSX) on one disk. Link to comment https://www.insanelymac.com/forum/topic/10806-dual-boot/#findComment-67766 Share on other sites More sharing options...
benson Posted March 3, 2006 Share Posted March 3, 2006 Chain0 worked for me with two partitions one one disk, when I installed OS X 10.4.1. Link to comment https://www.insanelymac.com/forum/topic/10806-dual-boot/#findComment-67821 Share on other sites More sharing options...
DrJägermeister Posted March 3, 2006 Share Posted March 3, 2006 That's definitely won't work in case of two partitions (XP and OSX) on one disk. It works fine with 2 primary partitions (XP and OSX) on one disk with the Darwin bootloader, the boot.ini or Grub.

DerAlSem Posted March 3, 2006 Share Posted March 3, 2006 Hmm... I've got HD with Two primary partitions. 1st - XP, 2nd - OSX. And two other HD with one partition each as HFS. chain0 doesn't work here - OSX doesn't start. Not sure what error it was...

Veeoh Posted March 3, 2006 Author Share Posted March 3, 2006 Hi - thanks for all the advice. Well the CHAIN0 method works and I am now sitting in a shiny 10.4.5 install on an AMD 64 3000. Shame I have an nvidia card with no acelleration - still at 1280x1024 though and most hardware works - only thing that doesnt is the nforce4 audio.
