No, it's a *syslinux* menu. The ISOs boot system is syslinux only. But
that's not a problem.

At a guess, the problem is that you have copied the ISO as a file into
a filesystem on the USB, rather than copied the ISO onto the USB
device as a whole. Then you use some other boot system (Ventoy?) that
lets you select and chain-load the kernal and initrd from that ISO
file But that boot system *does not then present the ISO file as a
mountable partition*, and therefore the installer doesn't find it.

That method works only with disyributions that are fully contained in
their initrd. Devuan installer ISOs require access to the ISO as a
mountable partition.

It's actually the same issue for chimaera ISOs, except that it's
startup is different. So it shows the initial installation dialogs as
if it would work. However especially it's partition utility is then
reduced to use FAT or ext2 only, and it will also have problems to
install the base system (because the software for other filesystems as
well as base system packages need to be loaded from to ISO after
mounting it).
