Hello All, I was having some problems trying to run the installmacosx.app from my flash drive. When i boot from it, it has the grey screen with a circle and a slash. from my research, I found out that this is from it not being able to find the boot.efi folder. Where in the installmacosx.app package do I drop this file, Thanks :)
 
What Mac OS X version do you use? And where did you get it and how did it get on the USB flash memory thumb drive?

Right now i'm trying to get Snow Leopard on my older laptop, 2007 mbp, dvd drive is broken. I got it from my snow leopard disc that I bought about two weeks ago. I used disk utility to format my USB drive as a bootable volume, then restored it with the disk image that I copied of SL. The image of SL is 10.6.6.

This error could be caused by the partition table for the USB drive not being set to GUID Partition Table (GPT) in Disk Utility. Do you know how to check the partition table format of a disk in Disk Utility?

Yep, Thats what it was set at. I made a new image today just to be sure.
