Disk Utility doesn't see any partitions - wtf?

Hi all,


I have tried to install 10.4.10, 10.4.11, and 10.5.1 without success. When I first started trying to install any of these versions, I was able to see my disk inside Disk Utility. Now, for some odd reason, when I boot into the Mac installer now, it says the entire disk is unpartitioned. I know this to be untrue because I'm dual booting XP and Ubuntu and am typing this post using the Ubuntu partition.


I'm currently using Grub for the bootloader. My partitions are set up accordingly:


   Device Boot	  Start		 End	  Blocks   Id  System
/dev/sda1   *		   1		6419	51560586	7  HPFS/NTFS
/dev/sda2			9291		9788	 4000185   82  Linux swap / Solaris
/dev/sda3			9789	   12161	19061122+  83  Linux
/dev/sda4			6420		9290	23061307+   f  W95 Ext'd (LBA)


/dev/sda4 is the Mac partition. I was under the impression I needed to make that.


Any idea as to why I can't see the partition scheme anymore? I'm trying this install on a laptop, which is why using a second hard drive isn't really an option, unless I want to swap hard drives.


Thanks for the help in advance.

Hi Big Puzzle,


Upon starting the OSX install DVD, have you been able to see the HDD using terminal?


Such as :

diskutil list


Then using:


fdisk -e /dev/rdiskX <- 'X' being the drive number which has the partitions


Then to get the partition table:



Did the partition table look similar to the output from Ubuntu?
