macbook triple boot help

[gambalf]

i have a macbook intel

this is how the partition look like

dev/sda1    EFI               fat32
dev/sda2    macosx        hfs+
dev/sda3    linux             ext3
dev/sda4    swap            swap
dev/sda5    winzoz          ntfs

i use rEFIt as bootloader: i have installed mac os x, windows xp pro sp2 and finally i have installed ubuntu (take me time to understand that i was forced to use LILO, but then it work out very great)

now i wanna change ubuntu and move to backtrack 2

i have tried a lot, at begin i was happy also cause BT2 use LILO (ubuntu don't), so i said to myself "well that's better, less work to do"

but there's no way i can make it work out: i install BT2, i screw some things up on lilo.conf and then try to mount the partition, but nothing work


if anyone can give me some "detailed" info, maybe someone that have done this before, i would really appreciate


thanks in advance



PS

sorry for the bad english, i'm italian

Potrei dirvi che come a faccia un'installazione di XP Ubuntu BT2. È molto facile e sono buono a spiegare come usare il GRUB. Non conosco il lilo. Non conosco nulla circa Macintosh. Spiacente per il mio italiano difettoso.

cheers

yeah, this can help me out a lot; i assume that, starting from what you offer, it won't be very different having mac instead of ubuntu, just cause they are unix based


if can you tell me the main "guidelines" to make a triple boot XP ubuntu BT2 it would be awsome

thanks again a lot

PS

you can speak english for that :P i understand it, i'm not used to write it only

The main difference is that if it were an ubuntu. I would recommend clean instlal on all OS's and I would do it like this:

1. Partition your drive like so using gparted (you can d/l gparted live cd):

/dev/sda1 windows
/dev/sda2 backtrack 2
/dev/sda3 ubuntu
/dev/sda4 swap
/dev/sda5 fat32 (if you really need this? it will be an extended partition)

2. Install windows
3. Install backtrack
4. Install ubuntu
5. Boot into ubuntu to edit GRUB file like so:

cd /etc/boot
cp menu.lst menu.lst.backup
sudo nano menu.lst

Your GRUB Back|Track entry will look like this:

# This entry automatically added by the Debian installer for an existing
# linux installation on /dev/sda2.

title bt (on /dev/sda2)
root (hd0,1)
kernel /boot/vmlinuz root=current ro 
initrd /boot/splash.initrd
savedefault
boot

You need to change it to this:

# This entry automatically added by the Debian installer for an existing
# linux installation on /dev/sda2.

title bt (on /dev/sda2)
root (hd0,1)
kernel /boot/vmlinuz root=/dev/sda2 
initrd /boot/splash.initrd
savedefault
boot

Then restart and all 3 OS's will work!


So you see, I know how to edit GRUB to make it work. But since you will have MacOS X, I do not know how to use rEFIt or lilo that well. Sorry.

ok that's fine

only i don't understand one thing: on board, BT2 should use LILO, not GRUB as loader.

am i right or not?

for what i know, ubuntu use GRUB as loader, BT2, like other slackware distribution, use LILO as loader........... it can be very possible i'm wrong


ok, i understand what i can do now maybe...... i will let you know

thanks a lot for the help

You have to edit lilo. That's why I said I could help you if it was Ubuntu, because I am very familiar with GRUB. I do not use Lilo and am ignorant to it. Sorry.
