Create a Chameleon USB Rescue Drive Using MultiBeast

It's always a good idea to keep a copy of iBoot on hand in case things go wrong with your install. You can easily boot from it and then choose your system drive.  But what happens when you don't have access to an optical drive?  Things can get complicated. Here's a guide that will help you install Chameleon and other necessary files on any USB flash drive.

PLEASE NOTE: USB Rescue drives will NOT boot the Mac OS X Retail DVD.  You will need an optical drive to do an installation using iBoot + MultiBeast.

YOU WILL NEED
  • A blank USB drive of any size- even an old 512mb one will work!
  • A computer running Mac OS X
  • MultiBeast
  • Your motherboard-specific DSDT from the DSDT Database
STEP 1: FORMAT THE USB DRIVE
  1. Boot into your existing Mac OS X Installation.
  2. Insert your USB drive.
  3. Open Applications/Utilities/Disk Utility
  4. Highlight your USB drive in the left column.
  5. Click the Partition Tab.
  6. Click Volume Scheme- choose 1 Partition
  7. Click Options…
  8. Select GUID Partition Table. Click OK.
  9. In the Name: field type: USB Rescue
  10. In Format: field select Mac OS Extended (Case Sensitive, Journaled)
  11. Click Apply, then click Partition.
STEP 2: DOWNLOAD YOUR MOTHERBOARD'S DSDT
  1. Visit the DSDT Database
  2. Download your motherboard's DSDT, and place the .aml file on the Desktop
STEP 3: RUN MULTIBEAST ON THE USB DRIVE
  1. Open MultiBeast
  2. In Select a Destination screen, choose USB Rescue (If you don't get this option,  press Continue, then select Change Install Location...)
  3. Select UserDSDT
  4. Click Continue, then Install
There you have it!  A Chameleon USB Rescue drive!  If you ever need to boot from it, go to your computer's boot menu at startup (F12 on Gigabyte boards) and choose the USB drive. When you get to the Chameleon boot screen, choose your system drive. If you have any issues booting your hard drive, you can always use -s to enter single-user mode to modify and repair disk, -x to enter safe mode, or -v for verbose mode.
