Two Pclos installed but only one shows in Start menu

[Maurice]

My setup is a triple boot one with Pclos 1012.02,Windows XP, and Centos

I have just installed Minime 1012-08 on a fourth partition but now my Pclos 1012-02 does not appear on the menu. It appeared when grub was setting up in Minime but does not show on the login menu.

The login menu only lists Minime, XP and Centos. I would like it to show if only for use as a backup.

It does appear in Dolphin along with the others and I can extract stuff from it.

Here is my menu.lst

Maybe .......

Of course that is on the assumption that I guessed the partition correctly .......

Thanks Just18 but it didn't work. I tried a few (hd0,x) but got "File system type unknown. Error 17 can't mount selected partition."

But the file system is ext4 the same as I always use.

Why don't you start by telling us which partitions is the previous PCLinuxOS 2012.02 is installed, and does it have it's own /boot folder?

As root, do an fdisk -l and post the results.

PCLinuxOS 2012.02 is on sda4 (extended) and does not have a /boot folder. Minime is on sda3.

Same a Just18, I would suspect your PCLinuxOS 2012.02 is in (hd0,2).  We'll need two to three more steps before we can sort this out.

Again on a konsole, type ls -l /dev/disk/by-uuid and post the results.

One the Run command (Alt+F2) and type kdesu kwrite /boot/grub/menu.lst then enter your root password on the password box.

Add the following before title linux-nonfb ... add empty lines before and after the stanza so you can distinguish the section.

title PCLinuxOS 2012.02
kernel (hd0,2)/boot/vmlinuz BOOT_IMAGE=linux root=UUID=bc869a96-e033-43c9-8755-700d8fa58422 quiet nokmsboot vmalloc=256M acpi=on splash=silent vga=788
initrd (hd0,2)/boot/initrd.img

Save the file and reboot.

Thought that was going to find it but instead I got - Error 15 File not found again. I've attached t part of menu.lst so you can see I typed it correctly.

This tells you that your installations are on sda2, sda5, and sda6. If you edit the boot stanza, previously given, to show (hd0,5) instead of (hd0,2) for both the kernel and initrd lines, it should boot what is there. You will also need to change the UUID to ecc9e2a2-5246-4ea5-9ab2-2cb9a53a6205
