I don’t know if this helps but I built a system to generate customized UEFI
boot menus for standalone DVDs. It’s not all pretty or anything. The menu ends
up being black/white vs the boot menus for BIOS.
I start with a generic OS DVD from the distro and extract it to a folder.
1) You need a partition under boot for the server you’re building and it
needs to be vfat..this is a section of my UEFI kickstart file..200MBs seems
fine:
part /boot/efi --asprimary --fstype=vfat --label EFI --size=200
part /boot --asprimary --fstype ext4 --size=1024
2) In my case of a standalone DVD, I have a script edit the
EFI/BOOT/BOOTX64.conf on the DVD:
1st to make it so the menu displays and to disable the timeout:
sed -i -e 's/^timeout .*$/# timeout 5/' EFI/BOOT/BOOTX64.conf
sed -i -e 's/^hiddenmenu/# hiddenmenu/' EFI/BOOT/BOOTX64.conf
I append sections like this for each menu choice:
title Install my application
kernel /images/pxeboot/vmlinuz ks=cdrom:/HPM/kickstart/hpmss_efi.ks
initrd /images/pxeboot/initrd.img
3) Finally I regenerate the DVD(this was edited for UEFI):
mkisofs -quiet -m RCS -joliet-long -o ${NEWDVD_LOC}/${ISO_NAME_FINAL} -V
"mlsk${BUILD_DATE}" -A "${ISO_NAME_FINAL}" -p "$USER@$(hostname)" -b
isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4
-boot-info-table -eltorito-alt-boot -e images/efiboot.img -no-emul-boot -R -T
-J -U -m TRANS.TBL ${NEWDVD_LOC_SRC} >/dev/null 2>&1
ISO_RC=$?
What I end up with is a bootable ISO that boots in either legacy/bios and UEFI
and loads the OS properly. The UEFI menu is pretty stark but it works.
Thanks!

Subject: Re: [cobbler] Enable UEFI Red Hat support on Cobbler (2.6.7) - HOW?
Hi,
it's funny that you ask because I tried to set it up with cobbler 2.6.7,
spacewalk 2.2 and UEFI for some days now.
At some point I gave up because google couldn't spit me out enough usable
information to get this running.
I got the system to load grub, but no menu was displayed to select the
corresponding kickstart entry...
I would be very much interested in further information on this topic, too.

Anyone have got UEFI support to work in Cobbler?
The support seems to be there in form of boot files etc... but it is completely
integrated?
BR,

Hi,
I have tried to find info how to enable UEFI boot in Cobbler but without
success.
If I understand it correctly, dhcpd.template needs to be updated to support
option arch = 00:07 (UEFI 64-bit)
(https://access.redhat.com/discussions/1168563)
Is there any document describing how to do this?
Cobbler complained on 'cobbler sync' after adding the if statement for adding
option arch into dhcpd.template.
All help is appreciated,
Daniel
