1. First, we need to prepare the USB drive. Fire up Disk Utility, select the USB drive, and go to the partition tab. Select “1 partition” from the drop-down menu, name the drive whatever you wish (i.e. Mac OS X Installer), make sure the format is “Mac OS Extended (Journaled)” in the next field, and then select the “Options” button below the partition map picture. Select MBR (Master Boot Record) not Apple GUID. Select “OK” and then apply your changes. Disk Utility will create 1 partition, use MBR, etc.
2. Now, “restore” the image of the DVD installer onto the USB drive. I’m using an image file (ISO) but you can use a DVD also. The image must be listed in the left pane of Disk Utility, if it’s not there, drag the image file over. Select the USB drive, go to the “Restore” tab. It’s pretty straightforward from here. Select your image/DVD as the source, and the USB drive as the target. And away you go.
3. Run OSx86 Tools, click install EFI/Run FDISK, choose to install PC EFI 8 on your USB Flash Disk.
That’s it. Just restart and boot from USB Flash Disk, and now we can start install Leopard from USB Flash Disk.
