Dual Boot Arch & Mac OS X(Boot device didn't show up after 30 seconds)

I was trying to Dual Boot Arch & Mac OS X on my new Mac book pro, I followed the steps (https://wiki.archlinux.org/index.php/MacBookPro)
Dual Boot (Arch & Mac OS X)
Two possibilities:
- Install Bootcamp, resize the Mac OS X partition
When Mac OS X installation is finished. Go on http://refit.sourceforge.net and download rEFIT (Mac disk image)
To install rEFIT, mount the rEFIT.dmg file (it is normally automatic).
There is an other way (refer to rEFIT documentation) but you can open a terminal then you copy /Volumes/rEFIT/efi/ to /
# cp -r /Volumes/rEFIT/efi /
To install rEFIT :
# cd /efi/refit/
# ./enable.sh
Now we can synchronized MBR with GPT partition table thanks to rEFIT so you restart your computer. You can see rEFIT, you press down key to access to the Partitioning Tool. You press y to accept.
Put your Arch Linux CD in the CD-ROM drive first then restart the computer. You can press C to boot from the CD or you can choose it in the rEFIT menu.
Now it is the typical Arch Linux installation.

So I burn the archlinux-2010.05-core-i686.iso to an blank disc on mac then restart the computer , press C to boot from the CD.
After choose to boot Arch linux and then I got this
Waiting for 30 seconds for device /dev/disk/by-label/ARCH-201005...
ERROR:boot device didn't show up after 30 seconds...
            Falling back to interactive prompt
            You can try to fix the problem manually, log out when you finished /bin/sh: can't access tty;
            job control turned off
[ramfs /]#
[ramfs /]#
Any ideas?
Thanks!

If i were you, I will boot to Mac OS X to ensure you are burning iso image to a cd and not burning a cd containing a single iso file.

This line:

You need to make sure that's the exact name of your iso disc. If it's not, it isn't a big deal. I've run into problems on this with my arch USB drive.

Once you get to the [ramfs /]# prompt, type in:

mv /dev/disk/by-label/(insert name of the current cd here) /dev/disk/by-label/ARCH-201005
exit

It should then be able to boot from the cd

did:

mv /dev/disk/by-label/(insert name of the current cd here) /dev/disk/by-label/ARCH-201005
exit

shows:

ERROR: mounting was successful, but /bootmnt/isomounts file doex not exist.

Then I checked:

cd /bootmnt
ls
archlinux-2010.05-core-i686.iso
exit

shows another problem /boot/init does not exist

exit

kernel panic!

Then I believe min's post above was correct. When you ls your cd, you should be getting folders and files, but instead you get the .iso file. You need to re-create the arch cd, burning it AS an .iso file, and not just burning the iso file to a disk
