If you only have room for two operating systems on your PC (i.e. WinXP and OS X) this may be of use to you.

 

Assume 10.4.3 is already installed (i.e on partition #1 of disk0). Assume 10.4.4 is installed on a different partition (i.e. partition 1 of your external usb drive). And assume you want to transfer the 10.4.4 installation to the 10.4.3 partition, thereby replacing 10.4.3 with 10.4.4. This may help you:

 

1. Boot into the existing 10.4.4 installation and make sure it works the way you want it.

 

2. Backup your 10.4.3 extensions folder if you think you may need them in the future.

 

3. Using terminal app, manually delete all files and folders from the 10.4.3 partition that you do not want to keep. The command is "rm -R <file or directory>" without quotes. You want to delete the kernels, hidden files, system files. You can leave the files "Desktop DB" and "Desktop DF" alone. Note that at this step you are destroying the 10.4.3 installation.

 

4. Next open Disk Utility. Go to the Restore tab. Make the source your 10.4.4 installation and the target your, now unbootable, 10.4.3 partition.

 

5. Uncheck the box "Erase Destination" so that 1) Your MBR stays intact, and 2) Any files you want saved on your 10.4.3 partition won't be erased by this process.

 

6. After the transfer is complete, don't reboot yet. First repair permissions on the new 10.4.4 partition.

 

7. Reboot into single user mode on the new 10.4.4 partition. Follow Maxxuss' 10.4.4 instructions regarding fixing the extensions in single user mode.

 

8. Reboot into the new 10.4.4 partition normally. Repair disk partitions again.

 

9. System should now be ready for use.

I have a 80gb with 10.4.4 on one partition and 10.4.3 on the other, both equal in size. My question is how would I expand 10.4.4's partition, it's all ready my primary boot between the two.

 

Expansion is not a problem. Let's say there's 10gb of data on the 10.4.4 partition. As long as the partition you are transferring to has at least 10gb of space you are good to go. In the case of your 80gb drive, you would have 70gb left over and available immediately to do whatever you want with.

 

This process isn't like some disk partitioning software that takes a 10gb partition and makes a 10gb partition on a 80gb disk, essentially wasting your other 70gb.
