[Polished] EFI Dualboot of existing Debian (Linux) and after installed Haiku 64 bit -- using Grub2 --> Works

[Kitsune64]

The 2 echo seem to feedback the same line but it’s appear really quickly on my screen.

And Maybe I have just made a type error cause now it work without prefix as in this screen:

I will restart again the computer for a new test of this file…
ok it work with this code:

#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

# for BIOS systems
menuentry "Haiku" {
        load_video
        insmod part_msdos
        insmod chain
        search --fs-uuid --set=root 1C93-8EC3
        chainloader ($root)/EFI/haiku/BOOTX64.EFI
}

Thank you
