    Question UEFI boot using SLES11-SP2 ISO

    I created rescue image using sles11-sp1 ISO using command(command is fine). it works fine(i mean in UEFI shell fs0:efi\boot\bootx64.efi will load rescue image). now I am trying to create rescue Image for sles11-SP2. when i try to use rescue image of SP2 to boot (in UEFI shell fs0:efi\boot\bootx64.efi is not loading rescue image showing msgs like "it's not external or internal commnad"),it's failing.

    by using original ISO image of SLES11-SP2 (in UEFI shell fs0:efi\boot\bootx64.efi will load rescue image) works fine. so what I did is
    /mnt:-mount sles11-sp2.iso /mnt/iso -o loop
    /mnt:-cp /mnt/iso/* /mnt/cpiso/ -rf
    /mnt:-cd /mnt/cpiso/
    /mnt/cpiso:-mkisofs -R -j -T -l -v -cache-inodes -o "dest path" -b "isolinux.bin path" -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot -b "efi path" -no-emul-boot . (current directory contents)
    I tried to boot using the ISO which is created using above command to boot,UEFI shell not recognising the bootx64.efi(boot loader).

    UEFI shell recognizing bootx64.efi of original SP1 ISO image and ISO which is created by extracting all the files of orginal ISO.(tried this one also)
    UEFI shell recognizing the bootx64.efi of original SP2 ISO image why not bootx64.efi of the ISO which is created by extracting all the files of orginal ISO.????

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    Although there has been a lot of progress in Linux dealing with UEFI "sercure" boot issues over the past 9-10 months, there are still a LOT of "dark corners" to deal with. Have you made any progress to share with us since you posted this query?
    Sometimes, real fast is almost as good as real time.
