I made TFTP boot share and it works for virtual machine and desktop computer (menu appears). But on notebook Dell Inspiron 7720 it shows few lines

enter image description here

and turns black.

Syslinux config is follows:

$ cat pxelinux.cfg/default
DEFAULT menu.c32
#MENU BACKGROUND moon800.jpg

MENU TITLE In The Moon Network

LABEL kaspersky
MENU LABEL Kaspersky Rescue Disk (WAIT!)
KERNEL memdisk
INITRD /iso/kav_rescue_10.iso
APPEND harddisk raw

LABEL rescue
MENU LABEL SystemRescueCd x86 4.7.1 (WAIT!)
KERNEL memdisk
INITRD /iso/systemrescuecd-x86-4.7.1.iso
APPEND iso raw

LABEL ubuntudesktop
MENU LABEL Run Ubuntu Desktop 14.04.1 LTS (WAIT!)
KERNEL memdisk
INITRD http://sagittarius-a/boot/ubuntu-14.04.4-desktop-amd64.iso
APPEND harddisk raw

LABEL ubuntu-installer-amd64-desktop-16.04-lts
MENU LABEL Install Ubuntu 16.04 LTS Desktop AMD64
KERNEL ubuntu-installer/16.04LTS/amd64/boot-screens/vesamenu.c32
APPEND ubuntu-installer/16.04LTS/amd64/boot-screens/menu.cfg

Content of TFTP directory is follows:

/var/lib/tftpboot$ ls
iso           libutil.c32  menu.c32     netboot            ubuntu-installer
ldlinux.c32   lpxelinux.0  moon640.jpg  pxelinux.cfg       vesamenu.c32
libcom32.c32  memdisk      moon800.jpg  sagittarius-a.jpg

The problem it doesn't show any menu at all.


I have replaced lpxelinux.0 for pxelinux.0 and revised all c32 to have them from single distribution of syslinux, but finally got the same result.

Why is it loading NBP file several (two) times?
