I'm having problems installing Lion onto a USB drive.
On a Lion MacBook Pro I saved the 'Install Mac OS X Lion.app' application, ran it and selected the USB drive as the destination of the install.
A few minutes into the process the machine reboots and comes up with a 'No Entry' sign.
All I can do after that point is a NVRAM reset and then boot back into the OS of the machine. When I look on the USB drive there is a 'Mac OS X Install Data' folder with about half a dozen files.
The USB drive is formatted as 1 partition, Mac OS X Extended (Journaled), GUID Partition Table. Under Get Info -> Sharing & Permissions, Ignore Ownership on this volume is un-checked. I have tried two different brand of drives: an Integral 16G and a Kingston Data Traveller 16G.
I guessing that what I'm trying to do should work - do people agree? Any ideas on where I might be going wrong?
(just to clarify, I'm not trying to create an USB install disk, I want to actually run OSX from the USB disk)
