It works great thx.

found it here http://forum.osx86project.org/index.php?showtopic=18627

 

boot with install DVD, hit F8 to get the prompt, and type -s to start in single mode.

 

when it boots to command prompt, type fdisk -e /dev/rdisk0

 

I am assuming you only have 1 hard drive. If you have more then one, then it could be /dev/rdisk1 and so on. You will get fdisk prompt. then type "show". Output will look like:

 

fdisk: 1> print

Disk: /dev/rdisk0 geometry: 24321/255/63 [390721968 sectors]

Offset: 0 Signature: 0xAA55

Starting Ending

#: id cyl hd sec - cyl hd sec [ start - size]

------------------------------------------------------------------------

*1: AF 0 1 1 - 1023 254 63 [ 63 - 390721905] HFS+

2: 00 0 0 0 - 0 0 0 [ 0 - 0] unused

3: 00 0 0 0 - 0 0 0 [ 0 - 0] unused

4: 00 0 0 0 - 0 0 0 [ 0 - 0] unused

 

See the * before partition 1? That means it is active, ie, bios will try to boot from it. If you don't see a *, there is no partition set to active, and you won't boot. To set a partition to active, type:

 

flag 1 (or whatever partition number it is, likely 1)

 

Then type quit to save changes and exit. type reboot to reboot, remove the DVD and you should be booting into OSX.

 

Maybe what you will see instead will look scrambled and it won't see an HFS+ partition. I think this happened to me at one point while I was trying to install. Then try this (but you will have to reinstall OSX after that):

 

fdisk -i /dev/rdisk0 (this will reinitialize MBR, just in case)

fdisk -a hfs /dev/rdisk0 (this will make one HFS+ partition that takes the whole disk)

 

then make this partition active, as described at start of this post.

 

Reboot from DVD, install OSX into the partition you see (don't erase it, just install into it), and you should be able to boot from hard drive. If you can't, do step 1 again to make sure install program didn't make it inactive again.

 

I'm sure there are many far more user friendly ways to do this, but I found it easier to just use what was provided already on install DVD.
