    How would i partition my HD so that i could have ~20gb that i could install another Mac OS onto. I know i can partition in Boot Camp but would i be able to install a Mac OS on that?

    I also tried using Disk Utility but it just gives me this and it only alows me to click the options button:

    The additional partition created by Boot Camp would be unused space. You can use that.

    I had the same problem. Bacl up your data. Put in your mac os x discs. Don't press install, click on file-disk utility and partition then press continue on the installer and it'll ask you which drive you want to install os x onto.

    That's a little annoying when Boot Camp is a decent free live partitioner in this situation.

    The partition that Boot Camp makes is unpartitioned, unused space.

    To piggy back off of this, you would want to make the partition with Boot Camp, and then boot from your Tiger CD. Once it has loaded, go up to the menu bar into utilities, and select disk utility. From there, select the partition of free space, and click the erase tab, and select Mac OS Extended (Journaled), and name it. Let it do its thing, and then do a normal install, using the new disk as your destination disk.

    if i do all this right is there any chance of something happening to both partitions with my 'real' OS X install on it.

    i backed up but is there a chance of this happening?

    No, everything should be ok. As long as you click on the right partition, and double check everything, you should be fine. Remember, you can be killed getting out of bed in the morning, but the chances of that are slim. The same applies here. I've partitioned the drive in my Macbook several times. Some with boot camp, some with Ubuntu, and some with Disk Utility on the install CD, and everything turned out fine each time.
