Fixing Real Mac installed with Chameleon with refit
1. Download and burn Refit (refit.source forge.net) onto blank DVD.
2. Insert DVD into DVD drive
3. When booting Mac, hold option key and select Refit.
4. Click the disk utility button.
5. When it asks to click Y or N, click Y.
6. On main refit menu, arrow key to Mac icon
7. Click icon and wait for 3-5 min.
8. Reboot Mac, while booting hold option.
9. Select Macintosh HD when asks for which system to boot.
10. Once desktop loads, delete all traces of chameleon. (the .chameleon file, the chameleon.pkg, and all else related. These are hidden files so you will need to know how to view hidden files.)
This is the process I used to fix it, hope it helps. Cheers!
