Backtrack 5 on a Macbook Pro

Question

Ok, so I have an Apple MacBook Pro MD313LL/A powered by OSX Lion.

What I am trying to do is to get Backtrack to run natively on it.

Since bootcamp only supports windows dualbooting, I found a workaround by using something called rEFIt. I enabled the rEFIt bootloader and used a GParted live cd to create an ext3 partition which I was eventually going to place the backtrack instance on.

The problem I encounter now is that when I try to use any kind of live cd (by pressing the "c" key while rebooting) the live cd fails. It gets stuck at the point where the filesystem has to be transfered into the RAM (initramfs).

I get prompted with the message: didn't find a medium with live content (or something like that...). This is strange because I was trying to use the same backtrack live cd which was fully working a few steps ago. I also tried inserting the live cd in some other PCs/laptops which worked correctly. I also tried burning new live cds of backtrack (different architecture this time) and Ubuntu.

Any ideas on what I could have done wrong or why this is happening ?

Solution

While I'm not 100% sure why it fails there is a workaround for this. In addition to burning the ISO to a DVD, burn it to a USB drive as well using dd, this will completely wipe out anything on the USB drive, so back up first!!

Determine your disk number by issuing this command:

diskutil list 

Insert the USB drive and run the command again. Identify what disk number your USB drive receives.

Now run:

sudo dd if=/path/to/iso of=/dev/diskX bs=1m

Where X is the number identified in the first step. If it gives you an error about 1m try using 1M instead. this will take a while ~10 minutes.

Now boot up as you described in your question (holding the 'c' key) but be sure to have the newly burned USB drive connected. Now it should boot up properly.
