I installed mac 9.1 just for SC but now I want to get it off my computer since I didn't want to play StarCraft anymore. I put the disk in the computer and I can't uninstall 9.1 without reinstalling my OS 10.4. I don't have a external HDD so that's out of the question. But if anyone has any idea of how to get rid of it.... please let me know.

Can't you just boot from the Mac OS X install disk and use Disk Utility (In the utilities menu) to delete the hard drive? Or do you have the hard drive in two partitions, one for Mac OS 9, one for Mac OS X?

Gone but not forgotten.
You should be able to drag the Mac OS 9 System Folder called "System Folder" to the Trash and empty the Trash. There should also be an "Applications (Mac OS 9) folder that you can delete along with it.

It shouldn't be more complicated than that, as long as you're working from an administrator account.

I take it that you already had 10.4 on the computer before you installed 9.1. Simply restart the computer into 10.4 and then drag the 9.1 files to the Trash. But, 9.1 does not take that much space on the HD, so why not leave it there?

For most of the answer's I had 10.4 before I added 9.1 Classic. I tried to get rid of the System folder but it wouldn't allow me to do so even on the Admin account on my computer. Mac OSX 9.1 Classic took 2gb worth of my HD away when i only have around 17gb left from 55.5gb on it

I believe there are two files in the System folder that make it "blessed" as a system folder: System and Finder. While booted into OS X, Go into the 9.1 System folder and take out "Finder" and put it on your desktop or something. The icon should change on the 9.1 System folder. If it doesn't, then reboot for good measure. You should now be able to put the folder into the trash, empty, then delete "Finder"

Here is the message I get when i try to erase the OSX 9 System folder. The operation cannot be completed becuse the item "System Folder" is required by the System.

I've delete all the other stuff and tried using Disk Utility to erase it, but then it doesn't work at all.

Put the "Finder" and "System" in the "System Folder" in the trash.
Rename the "System Folder"
Reboot
You can now put the renamed system folder in the trash.

Thanks for the help it actually worked when I removed "Finder" from "System Folder". From there the icon for osx 9 was gone and bye-bye OSX 9.1. Later that night I told a Starcraft buddy about my dilemma and he found a OSX SC installer for me.

That only works if he's already in OS X. If he's in 9, it won't let him.

edit:

All you really should have had to do was shut down the computer, press the power button to turn it on, and then hold down the option key until you get a screen with a couple of icons on it. Then you should have selected the one with an "X" on it and hit the right arrow button on the screen. This would have restarted you in OS X. From OS X you can simply drag "System Folder" and "Applications (Mac OS 9)" to the trash.
