    I use Carbon Copy Cloner for this type of thing. Works better and lets you know if it will be bootable before you start.

    Is that freeware? I'm not really trying to purchase some more software to do this.

    I guess if I have to I can use a DVD... just slightly irritating that this won't work.

    You need an 8 GB flash drive.

    There's a guide at OSXDAILY for exactly this. I used a fresh 8gb sandisk thumb drive just to be safe. It worked flawlessly and the only software you need is Disk Utility (already on your Mac)

    Edit: didn't see the pic..clearly, you're aware of the method. However, as stated above, you need an 8gb drive.

    I know... I think its cos it unpacks things bigger so that it takes up more space? Not 100% sure.

    Yup, Looks like it needs 4.18 GB.

    CCC is free from bombich.com

    Guess it is a dvd for now. I still need my 8GB usb for Snow Leopard.
