Here's a small howto about dual booting Mac OS and Windows xp with the Windows bootloader method.

• Partition your hard drive accordingly.
• Download Mac OSX Tiger DVD.
• Install Mac OSX on a partition.
• Restart the computer with a Win 98/ME start cd or disk.
• Start fdisk, set Win XP partition as active.
• Copy chain0 to c:\.
• Add chain0=”Mac OSx86” to boot.ini in Win XP.
• Restart.
• Enjoy dual booting.

Hi!

Thanks for the post, it was very useful.
Now I have two strings in my boot choice (ntldr): XP & osX, but the problem is that once I have chosen the osX I should select the partition (osX loader), there the Mac OS is situated. No good. Any suggestion how I could solve it?

Did you tried to tap on F8 after selecting the OSX partition ? For more information see here.

Sure I done that, I've read all your posts)) Actually I'm able to boot Mac OS. My boot process looks like:
I. I'm in ntldr and have to select to boot either XP or Mac OS, XP boots by default:
1. XP -
2. Mac OS

II. I'm in darwin loader and I have to select Mac OS *again*:
1. XP -
2. ...
3. ...
4. Mac OS
Otherwise it boots in XP (e.g. ntldr) then directly in XP. So I have to select Mac OS two times every day. It drives me crazy)
What I'm looking for is some way to tell darwin loader to boot in 4th partition directly. I've tried to add "rd=disk0s4" (which is my Mac partition), but it changed nothing.
Don't know if there is any way to do this. But thanks anyway)

Well if you manage to set the Mac OS partition active, the darwin bootloader automaticly boots up Mac OS.
Here is a tutorial to set a particular partition active.

Good luck !

Based from the theory, I think it should work. Since the Mac detects the partition of Win, the itenerary becomes:
1. Partition HDD
2. Install WinXP (assumed)
3. Install MacOSx86
4. Set the MacOS partition as active partition

I have further question:

First of all, thanks to your docs on upgrading MacOSx86 to 10.4.10.
Does upgrading the mac 10.4.10 affects the dual booting ?

Thanks
