Bootiso fails to run on Fedora 27 system with syslinux packages installed.

Bootiso: UEFI boot check validated. Your USB will work with UEFI boot. Bootiso: Partition label automatically set to 'CCCOMA_X64F'. You can explicitly set label with '-L, --label' option.

Syslinux could not find kernel image hbcd boot chain c32 http://is.gd/YOiHEt.

I can confirm that setting SYSLINUX_LIB_ROOT does not work with v3.2.2 echo $SYSLINUX_LIB_ROOT /usr/share/syslinux./bootiso ~/Downloads/Win10_1809Oct_English_x64.iso bootiso: Found non-hybrid ISO; inspecting ISO for boot capabilities.

However doing: sudo mkdir -p /usr/lib/syslinux/bios sudo rsync -av /usr/share/syslinux/ /usr/lib/syslinux/bios/ found in the original post did work and solve the issue.
