Describe the bug

bootiso: Could not find a SYSLINUX bios folder containing c32 bios module files on this system. Exiting...

Even when I set the environment variable as suggested here: https://github.com/jsamr/bootiso#distros-tweaks export BOOTISO_SYSLINUX_LIB_ROOT=/usr/share/syslinux

Expected behavior (for behavioral bugs only)

I expected bootiso to work, instead it fails saying it could not find SYSLINUX bios folder, as described above.

Reproduction

Run bootiso on Fedora 34.

1. Run bootiso -d sdd /home/wes/Downloads/Win10_21H1_English_x64.iso with this ISO

2. See error log:

$ bootiso -d sdd /home/wes/Downloads/Win10_21H1_English_x64.iso
[sudo] password for wes:

Suggestion fix (optional)

I was able to get it working using the instructions in the comment from this old bug report, here: https://github.com/jsamr/bootiso/issues/29#issuecomment-478384808

The best solution would be to use the bios folder only if it exists (which is not the case on Fedora).

As a workaround you can apply the patch used in OpenMandriva:
