dual boot machine wont boot backtrack from the harddrive?

Hello all,

Didn't quite know where to put this issue i'm having. but here it is...

Basically have been dual and triple booting my macbook (white 4.1) for ages with Windows (shudder), Linux and obviously Mac OSX...

usually never been an issue, and the Linux distro of choice being Ubuntu.

But i cannot get backtrack to boot from hard disk.

It installs fine, since its the same installer as Ubuntu (near enough :P) i seem to be doing everything as normal.


HOWEVER... when i go to boot the Linux partition containing backtrack, i juts get a black screen with a flashing white cursor...not even a grub boot loader, and yes the installer said it installed.


If anyone has any idea, would be great to hear from you :D


Thanks

[SOLVED]

basically turns out because its a Mac, using EFI boot scheme, grub wasnt being set up...thats my reckoning on things anyway :)

to solve this just popped in an Ubuntu Live cd and installed grub manually

here is the link i got it from

How to install Grub from a live Ubuntu cd. - Ubuntu Forums

but just in case it breaks here are the steps:

1. Boot up Live CD

2. type in a terminal window

sudo apt-get install grub

3. enter the following at the prompt you are given, follow closely! :)

sudo grub

find /boot/grub/stage1

root (hd0, 2)

setup (hd0)

quit

this should return you to your bash prompt.

where 2 is the partition number returned by the find command.

SORRY for wasting anybodies time on the forum.
