Hey, I'm trying to install ubuntu 8.04 on my MacBook2,1. I have the live CD and here is what I've done so far.

-Used Boot Camp to partition my harddrive. Gave 'windows' 10 gigs.
-put the live CD in, restarted holding down 'C' went to the ubuntu menu thing. Selected 'Install Ubuntu.'
-Went through the first few steps, language, keyboard, etc.
-At my partition menu I:
-Deleted /dev/sda3 (My 10GB windows partition)
-Created new swap partition: /dev/sda3 swap 936MB
-Created new ext3 partition: /dev/sda4 ext3 9500MB mounted at '/'

-So my partition table looks like this:
type | mount | size
/dev/sda
/dev/sda1 fat32 209MB
/dev/sda2 hfs+ 109387MB
/dev/sda3 swap 936MB
/dev/sda4 ext3 / 9500MB

-The installation proceeds as normal and it tells me to restart
-I click the restart button, it restarts, ubuntu loads.
- my live CD pops out and it tells me to 'remove the disk, close the tray (if any) and press enter.'
-I press enter and it restarts again. It loads up to my EFI (rEFIt) I can choose Mac OSX or Linux, I choose Linux and press enter.
-A black screen comes up with white text across the top that says: 'No bootable device --
insert boot disk and press any key.'
-Pressing keys doesn't do anything. I put the live CD in and still nothing.

If anyone could help me out here I'd really appreciate it.
Maybe I'm just missing something but I've read and reread the guide and cant figure it out, it seems as though I've done everything it told me to.

Thanks alot guys
