Good to hear you made it work. It didn't work for @e.e.p. Can you please list down the steps so that e.e.p and others can benefit from it?
@spandey: yes, thanks for asking that each of the steps be detailed, or is it that using "Hugh T's" coding is exactly, more or less, what is needed? But it looks like what "LuvMySubi" added that makes the final difference; it appears that the problem all along with the LMDE installer is that it isn't or doesn't provide a way to either make or mark the Boot partition, so GRUB doesn't know where to put itself . . . .

@Luv: When you say, "small partition" what does "small" mean? Is this like the 1 MB that is used for Yaboot in other Linux installations? And then does the placement of it have any importance? Like it should be before the OSX partition just after the rEFIt boot partition or after it just in front of the Linux partition? Thanks for any details . . . .
