I installed Ubuntu 10.10, and afterwards Backtrack 4 R2 but I unchecked the bootloader option. After that, I logged in Ubuntu, run the "update-grub" command, it said that it had found Backtrack on the given partition, but it doesn't seem to display it in the grub.cfg.

Any suggestions? Should I just install BT4 again and leave the "Install Bootloader" option checked?
