I don't think GRUB needs updating, it looks directly at the file in the parition it boots from. Remember that being one advantage of many over LILO. I might be wrong though!
menu.lst is the way if you have grub. In grub2, you can just run update-grub in terminal.
If i have 3 distros installed and lets say i put in Slitaz as the fourth, then i just run this update-grub in terminal, and at next boot, slitaz will be there as well.
I can't boot slitaz cooking.I install slitaz in my acer netbook. I use grub2 bootloader. My system has 3 OS already such -XP, Ubuntu 9.10, and Ubuntu NBR 9.10. I installed slitaz in a separate partition- /dev/sda10 Now I used seawolf's configuration with using number in my case.. /sda10. here is my config, but doen't boot:
title SliTaz GNU/Linux (cooking) (Kernel 2.6.30.6-slitaz)
Actually when I installed I formatted the partition as "ext3" and I saw as..../dev/sda10. So, in my case, should I edit as "ext2" and ""/hda10.
As my OS was upgraded from ubuntu 9.04 to 9.10 and grub to grub2, Today I deleted my ubuntu system and I did clean installation of Ubuntu karmic 9.10. I installed Slitaz again.It was horrifying me. it doesn't boot. Error message was given as there no partition. I am right now in the middle of re-installation of my Ubuntu 9.10. Thanks guys. I will keep trying .
Success. Thanks all forum members.For those new user, it might be helpful how to install Slitaz cooking with the following summary. I just summarised the information given by the members: Here it goes-
