This is actually because of a BIOS setting. Start the computer and press F2.
Navigate to Advanced
Go down to System Configuration and press enter
You will see something called Boot Mode. It is probably set to UEFI Boot. Select and Press Enter.
Choose CSM Boot.
Press ESC and then Exit with saving changes. You computer should now boot again from the Disc/USB.
When done you must set it back to UEFI or Windows 8 will not boot.

How to make a bootable USB disk in OS X from an ISO
Use this at your own risk. I am not responsible if this destroys your USB drive.
Open up a command prompt
Run the following command:
hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/something.iso
Change the first path to where you want to save it "somename.img"
The next piece is where the iso is located. Write the path to where its located.
Type "diskutil list" in the command prompt to get a list of devices.
My USB drive was /dev/disk2. Yours may be different.
Next you need to unmount the drive. Type "diskutil unmountDisk /dev/disk2"
*Obviously change that command to what your USB disk is*
Next from the command line run sudo dd if=/yournewimage.img.dmg of=/dev/rdiskN bs=1m
And change rdiskN to what you found from the diskutil. Mine was rdisk2.
Enter your password and wait.
It looks like nothing is happening but it is. Just wait longer. Trust me it will finish.
When it finishes, type diskutil eject /dev/diskN
Again change "N" to the number you used previously.
Reboot and boot from it.

How to Install OS X Lion/Mountain Lion from a USB Drive
First you have to purchase it from the App Store.
Locate the the Lion app in the Application Folder (Did notice that I already had it downloaded previously and moved it to my desktop. It actually updated the Lion App on the my desktop and did not show up in my Applications Folder, just an FYI)
Right click and click "Show Package Contents" Go to Contents -> SharedSupport
Plug in the Thumb Drive. Once it shows up on the left hand side click the Top Level for that thumb drive. You'll know your on the right level if you see the Partition tab on the right hand side.
Click Partitions and select 1 Partition.
Select Mac OS Extended (Journaled) as the Format
You can name it whatever you want.
