I had a triple boot setup, with XP, and two other linux distros.
I use GRUB and found it much easier to simply let SUSE configure this.
When going into XP I too had a second GRUB come up, from a previous install of Ubuntu and some boot.ini entries. If you check boot.ini on the Win setup and make sure only paths to windows are listed it should boot straight in rather than giving options…
Use GAG, you can multiboot 9 OS with it, It has a gui and a number assigned for a particular operating system but you need to be wise to note down # of every boot partition and add that accordingly. It is a small program but very useful for multibooting. Try and keep data partition separate so that you wont loose anything in case of failures.
putting 137 linux distro on 1 machine doesnt make a sense (the guy must be a pensioner). You can catagories 4-5 variants in Linux and use those. The person here asked for a simple tool that can boot the OS of his choice without having to go thru multiple chain loaders.
Install suse last and get fdisk -l, check the boot partitions, go to yast-system-bootloader, hit add and click other system. name the section like Mac or Windows and mark the partition that you wish to add for a triple boot. Hit ‘OK’ and leave.
You can also throw in the installation CD, go to repair, and reinstall your bootloader (Grub 0.97) to your MBR, after this you should have one single boot menu to list all OS’s, as long as you went to the boot.ini win files as previously suggested. If you don’t like the way it lists your OS’s, the necessary changes can be made in your menu.lst file.
Ok I know nothing about eEFIt. But let me restate the problem.
Booting into the eEFIt boot manager it chains to the grub boot abd thus shows a menu. You don’t want this. You want it to go straight to the OS.
If this is correct you could simple set the default timeout to autoboot to 1 sec. this would flash the grub screen but would start the default grub boot option almost immediately.
So we would need to see menu.lst
become root in a console then
