Hey Bill, This is not an uncommon thing to be doing, and there are definitely challenges in terms of MBR/EFI, and media in doing this. I've culled some of my key resources as a short list of URLs here: http://www.tuxfixer.com/mount-modify-edit-repack-create-uefi-iso-including-kickstart-file/ I'd pay very close attention to that github gist that points out that efi image that you'll need to mount and modify (there are actually three locations you need to edit/modify for the bootable media: EFI/BOOT/grub.cfg, isolinux.cfg, and within images/efiboot.img). The mkisofs command that we're using at ${EMPLOYER} is: mkisofs -o "${BASE_DIR}"/"${ENV}"/custom_${today}.iso \ We're clearly working on/with CentOS, but you should be close with the above.

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? |
