Installing Ubuntu 12.04 LTS on Mountain Lion I'm working on a MacBook late 2008 Unibody Aluminium with Mountain Lion on. 
I'm trying to mount Ubuntu 12.04 LTS 64 bit on a USB stick in Mountain Lion but it seems impossible. 

I've read all the documentation on how to install it on the Ubuntu
site with all the command lines etc., but it's not working. I get errors like "No mountable file detected" when trying to open the .iso file. 

I'm specifically looking to have an OS that doesn't make high frequency noises. Has anyone been able to install 12.04 LTS Ubuntu on their Mac (with Mountain Lion)?
This can be achieved using Linux USB Creator For Mac.

Instructions:


First just select the linux distribution you want to use. You can either select from the list or browse for a Local ISO file to use.
After choosing Ubuntu you can browse for your USB device.
The program will then download the ISO, Format the disk, Copy the ISO and Install the Bootloader.
Your USB Drive is now ready to use. Simply boot up your mac while holding the “alt” key and select the drive.


A YouTube video is also included &amp; can be viewed from the above link to complement.

Please note: This program hasn't been updated since the introduction of OS X 10.8 Mountain Lion.
