Exactly this point is my problem on my macbook pro 5.5 and Ubuntu 12.04

When i install the bootloader in the root partition then i get later a black screen with blinking cursor and nothing happen , no boot.

But when i install the bootloader on my default main hard disk i can boot without problems.

I dont know if this is also right.

Can someone help me?

Must i use gparted before i start the installation or can i make the partition things also in the normal partition menu form the installer?
