USB Stick Pausing at Grey Screen? LOOK HERE

People have been complaining for a while now about their netbooks freezing on the OS X Grey screen when the USB drive is booting the installer program. I figured this out a while back, and answer many questions here (and on the InsanelyMac forums) about this problem.

If you are using OS X Lion (v 10.7) to restore your image file to your USB stick, then you will NOT be able to get this installation to run. When Lion was made, tweaks to Disk Utility (specifically the restoration process for restoring disk images to other places [such as your USB stick/SD card] created problems with hackintosh users all over the place. If you are attempting my guide (or most others for that matter), you need to use a computer with either OS X Leopard (v 10.5) or Snow Leopard (v 10.6). These both have safe versions of disk utility to restore the image file to your USB stick. Lion will NOT WORK.
