Make sure your grub is updated to the latest version.


If you have an older version and update it should see all your operating systems and make menu entries for each one.


or you could try to update the menu entries with the following commands

sudo update-grub


sudo update-grub2


If your SL is found and installed you might want to examine the script used to boot SL. This is where the configuration is on my system.

sudo gedit /boot/grub/grub.cfg


You will see that a few things happen before the kernel is started. Like the kexts from /E/E and /S/L/E and mkexts, if a DSDT.aml is in your /E folder it will be loaded... etc.


I currently tripple boot with SL-10.6.5, Win7, Ubuntu 10.10. I have Win7 and Ubuntu on one drive, and SL on its own drive. I can use grub or Chameleon to boot into SL. I would prefer to use grub. But I am still figuring out which kexts to use to set the motherboard information.
