Re: Help Creating Linux ISO

[Thomas Schmitt]

Hi,

> Could you let me know what I am doing wrong?

There are surplus EFI boot images by the arguments beginning at the second
-eltorito-alt-boot.
It might be confusing to the boot firmware that the same EFI boot image is
listed twice in the El Torito boot catalog.

This would make the ISO without duplication of EFI images:

  xorrisofs \
    -o target/csg-3.0.0.0_RC16.0.0.65SBR-x86_64-HYBRID.iso \
    -b isolinux/isolinux.bin \
    -c isolinux/boot.cat \
    -no-emul-boot -boot-load-size 4 -boot-info-table \
    -isohybrid-mbr /usr/share/syslinux/isohdpfx.bin \
    -partition_offset 16 \
    -eltorito-alt-boot \
    -e images/efiboot.img \
    -no-emul-boot -isohybrid-gpt-basdat \
    target/dvd

>From where did you get images/efiboot.img ?

If you used a RHEL ISO as source of files:
Does that ISO boot ?
Is it available for public download ?
What text output do you get from inspecting that ISO by
  iso=...path.to.original.ISO...
  xorriso -indev "$iso" -report_el_torito as_mkisofs
?

If you made efiboot.img yourself:
What's in it ?
Did you compare the files in efiboot.img with those in an original RHEL
ISO ?


Have a nice day :)
