I am creating a custom installation ISO using kickstart. This install ISO is based on SL 7.2.
When I burn a DVD from this ISO I can boot from the DVD and the install menu come up as expected.
When I use dd to copy the ISO to a USB key and try to boot from the USB key the install menu does not appear and the system boots from the hard drive.
I tried using dd to copy the SL7.2 ISO to a USB key. When I try to boot from this USB key the install menu comes up as expected.
What files on the SL7.2 have to do with booting from the USB key?
Is there a mkisofs option I should be using to make booting USB key work?
