Hi Roland,

Thanks for your reply and for the information. I am building on amd64.

I notice that you explicitly add '--binary-image iso-hybrid', which is
the default value for amd64.
Are you building on an arm64? Because there, the --bootloaders option
defaults to only EFI, no BIOS boot support is added.
If so, on which device are you building?

live-build uses only a few packages from the host. The other packages
are installed in a discardable chroot-environment.
