Unable to boot OS X86 with GRUB

[greencheese]

Hello all. I have a DVD of "Mac OS X 10.4.9 Myzar AMD-Intel" which I created a partition (type AF) using cfdisk. I then booted the DVD, erased the partition using Disk Utility, and then installed successfully. I have been using GRUB since I dual booted Windows XP and Ubuntu 7.04, so I created a GRUB entry using guides I found on the wiki. However each different configuration yielded a different error. For example,

title           Mac OS X
root            (hd0,3)
makeactive
chainloader     +1

gives a GRUB Error 13, while

title           Mac OS X
root            (hd0,3)
makeactive
chainloader     --force +1

gives a GRUB Error 18, and

title           Mac OS X
 rootnoverify            (hd0,3)
 makeactive
 chainloader     +1

also gives a GRUB error.

Here is my current partitioning table:

/dev/hda1 XP ntfs primary 45 GB

/dev/hda2 Ubuntu ext3 primary 45 GB

/dev/hda3 extended

/dev/hda5 fat32 logical 50 GB

/dev/hda6 swap logical 2 GB

/dev/hda4 OS X hfs+ primary boot 10 GB

 

Hardware:

AMD Athlon 64 3500+ Venice (SSE2, SSE3)

1 GB RAM

ASUS A8AE-LE (ATI Xpress 200 IGP)

 

Any help would be appreciated in getting OS X to boot with GRUB.

Having osx on a primary which is located after an extended partition (which is your case) is know to cause problems.

Unfortunately low-grade guides don't mention this problematic situation.

 

One possibility would be to relocate the osx primary partition before the extended (hopefully the partition table will be resorted accordingly). Of course this involves moving a lot of stuff, and stresses the hard-drive.

Thanks for the reply. Would using Windows XP's boot loader instead of GRUB work despite the partition arrangements?

it's not a grub problem.
