    First of all, check the format of the thumb drive, as well as its partition scheme. In order for this to work, the drive MUST be Mac OS Extended (Journaled) format with a GPT (GUID Partition Table) partitioning scheme (assuming you'll be booting the installation on an Intel Mac, since PPC Macs don't support USB boot).
