Pre-requisites For This Stage

• ISO file downloaded and on the desktop
• Working MAC booted up and at the desktop
• USB Thumbdrive inserted
• Chameleon Bootloader downloaded and extracted to a folder on your Desktop
• PC_EFI V10.1 Bootloader download and on your Desktop
• Extra.zip downloaded and Extra folder extracted to your Desktop

Steps For This Stage

Warning: You are following these steps at your own risk.  You can and possibly will destroy all data on the netbook at some point in this install so back it up if it contains valuable files!

Step 1 – Partition The USB Thumb Drive

1. Open Disk Utility
   • Click Go > Utilities > Disk Utility
2. On the left side, select your USB Thumb Drive
3. Click the Partition tab on the right
4. Under Volume Scheme select 1 Partition
5. Click Options button
6. Select Master Boot Record > Click OK
7. On the right, enter a name for your Volume – I’m using MacBoot
8. In the Format drop down field select Mac OS Extended
9. Click Apply button
10. When asked Are You Sure?, click the Partition button if you are sure.

Step 2 – Restore The ISO File To The USB Thumb Drive

1. Still in Disk Utility, click the Images menu and then click Scan Images For Restore…
2. Browse to where you saved your ISO file (mine’s on the Desktop), select it and click Scan
3. At this point, one of two things will happen:
   • Your scan will be successful in which case you can proceed below when it’s complete
     OR
   • You will get an error message saying Unable to scan “filename.iso.” (Invalid Argument).   If you get this error message then skip down to the Troubleshooting section at the bottom of this page.



4. When you scan is complete, highlight your newly created partition on your thumb drive on the left hand side of Disk Utility
5. Click the Restore tab on the right
6. Drag your thumb drive partition from the left side (mines called MacBoot) into the Destination field on the right
7. Drag your ISO file from the Desktop (or browse for it if you prefer by clicking the Image button) into the Source field on the right side
8. Select Erase Destination checkbox
9. Click Restore and Restore again
   
10. At this point, one of two things will happen
    • Your Restore process will chug away happily for a little while (enough time to get a coffee, believe me) and you can continue with the steps when it’s finished
      OR
    • You will  receive an error message such as: Restore Failure.  Could not find any scan information…If you get this error message then skip down to the Troubleshooting section at the bottom of this page.

Step 3 – Make The Thumb Drive Bootable

1. If you haven’t already done, close Disk Utility but leave your Thumb Drive inserted
2. Open Terminal.  You can find this in Applications > Utilities
3. Type diskutil list and press enter.  You will see something similar to image below.
4. Take a note of the number of the disk under the IDENTIFIER column as circled in red below.  As you can see, mine is 1 (One) (i.e disk1 and disk1s1)
5. Now you need to change directory into the i386 directory which is inside the Chameleon directory that you extracted to your Desktop.  You can do this by issuing the cd command and typing the remainder of the path which would be something like:
   • cd /Users/your_username/Desktop/Chameleon-2.0-RC2-r640-bin/i386
   • Tip! A quick and easy way to do this in Mac OS X is to type cd and then simply drag the i386 folder (yes using your mouse) right into the Terminal window and releasing the mouse button.  It will fill in the correct path for you.  Isn’t Mac wonderful
   • When you’ve entered the correct cd command, hit Enter.
6. Now enter the following commands and be sure to swap the items in red with the correct ones from your system as discussed in step 4 above and press Enter after each.  You may be asked to enter your password.  Just enter it and press Enter again.
   • sudo fdisk -f boot0 -u -y /dev/rdisk1
   • sudo dd if=boot1h of=/dev/rdisk1s1
   • sudo cp /Users/your_username/Desktop/boot /Volumes/MacBoot
7. Close Terminal
8. Back on your Desktop, you should have downloaded and extracted Extra.zip.
   • If not go back to the “What You’ll Need” stage of this article and download it.
9. Now copy the Extra folder (a simple drag n’ drop is fine) from the Desktop into the root directory of your Thumb Drive
10. That’s it!  Mac OS X Bootable USB Thumb Drive created.
    • Make sure it looks similar to the image below.  The most important of folders being highlighted in red.
