I have Ubuntu 10.10 installed and used to dual-boot Fedora, but I replaced Fedora with Pardus.

After the install, I went into ubuntu, and did a sudo update-grub. It detected my Pardus 2011 install there. When I rebooted, it did not show up in my grub2 menu however. I went back to Ubuntu and did it again...then checked the grub.cfg, and it is not there. I have read that Pardus uses a grub legacy.

How can I get Pardus into my grub2 menu?


sudo fdisk -l

Found Pardus 2011 (2011) on /dev/sda3

Yet after this, I go to grub.cfg, and Pardus is not there.

This question came from our site for professional and enthusiast programmers.

When you installed pardus, you should have made the installer to not to install the bootloader on the MBR and instead do it on the pardus partition? Grub2 will not update be able to boot pardus if you have not done this.

I didn't install the bootloader for pardus at all. And if I believe correctly, my bootloader for Ubuntu (Grub2) is installed on the Ubuntu partition. – Ibn Ali al-Turki Jan 24 '11 at 7:16

A bootloader installation is required for each of your Linux installations. But, one of these bootloader programs should be installed on MBR. The MBR on a disk is only 512 in size and the rest of the bootloader is installed on the /boot directory.

So, Pardus and Ubuntu BOTH need to have their bootloader programs installed in their respective /boot directories. Only one of these bootloader programs, either that of Pardus or Ubuntu, needs to be written to the MBR. The other boot loader program should be written directly to the system partition.

You shouldn't choose to not to install the bootloader for Pardus. Install Pardus but choose not to install the bootloader to MBR and instead choose /boot directory. Next boot into Ubuntu and update grub. It will then recognize the Pardus partition and copy its boot entry to grub.cfg.

For basic multiboot info, try this How To DualBoot or MuliBoot Operating Systems.
