   I need to dual boot. I can't figure out how to edit the menu list to reflect my other distro. This is my fdisk -l.

   Disk /dev/sda: 320.0 GB, 320072933376 bytes
   255 heads, 63 sectors/track, 38913 cylinders
   Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot Start End Blocks Id System
   /dev/sda1 1 29029 233174016 83 Linux
   /dev/sda3 29030 38914 79394817 5 Extended
   /dev/sda5 29030 38401 75274240 83 Linux
   /dev/sda6 38401 38914 4119552 82 Linux swap

   These are my partitions

   /dev/sda1 which I believe is my slitaz partition
   /dev/sda5 which is the other distro

   here is a copy of my current grub menu.lst. you can see where i've attempted to add in the correct information with no luck

   # For booting SliTaz from : /dev/sda1
   #
   title SliTaz GNU/Linux (cooking) (Kernel vmlinuz-2.6.37-slitaz)
   root (hd0,0)
   kernel /boot/vmlinuz-2.6.37-slitaz root=/dev/sda1 quiet

   title Ubuntu
   root (hd0,5)
   kernel /media/disk/boot/vmlinuz-3.2.0-31-generic root=/dev/sda5 quiet

   also:

   i noticed there is grub V2 out. is it smart to upgrade to grub 2 or to keep the current grub?

   I believe you should change root (hd0,5) to root (hd0,4). It should work.

   I find Grub2 more complicated. At least it will take some time to learn to work with it. Editing the menu.lst is less easy in my experience.

   Also, Ubuntu requires an initrd command similar to

   initrd /boot/initrd.img-3.2.0-31-generic-pae

   - you would need to change the file name to suit your installation.

   Hi gap on your ubuntu have three kernel update, I think the last is correct and try this menu.lst

   title SliTaz GNU/Linux (Kernel 2.6.37-slitaz)
   root (hd0,0)
   kernel /boot/vmlinuz-2.6.37-slitaz root=/dev/sda1 quiet

   title Ubuntu
   root (hd4,0)
   kernel /boot/vmlinuz-3.2.0-31-generic root=/dev/sda5 quiet
   initrd /boot/initrd.img-3.2.0-31-generic

   or change version 3.2.0-31 on another two version you have

   Yeah, I cought the error myself and moved it and it worked, so thank you for your assistence :)

   Can you explain how the process works?

   The root is on the primary hard drive, 4th partition (how is it the 4th?)

   the kernel is pointing toward a kernel in the file system?

   What is initrd?

   Hi gap,

   GRUB uses next name translations:
   hda* - (hd0,*)
   hdb* - (hd1,*)
   ...
   hda1 - (hd0,0)
   hda2 - (hd0,1)
   ...
   hda5 - (hd0,4)
   ...
   Why? GRUB is for GRand Unified Bootloader and it can boot not only Linux. So it not link disk (partitions) names neither with Linux or Windows names. It uses its own ones.

   InitRD is for Initial RAMDisk, virtual disk with programs that loads to RAM while booting. How it works in the traditional big Linuxes? It contains very small Linux system that helps to big system to boot. Usually it contain busybox environment and drivers for various filesystems to boot big linux from.
   But, small Linux distros like SliTaz, Puppy or TinyCore completely contained in the initrd.
