To make a boot-usb using Syslinux and Grub4Dos.
1. Format the USB as fat32 filesystem
2. Mount the USB and open Terminal into USB (or via Termial .. cd /path/usb)
3. copy menu.c32 to the USB
cp /usr/lib/syslinux/menu.c32 .
Notice the comma also in the command!
4. Make ldlinux.sys file
sudo extlinux --install .
5. Make a syslinux.cfg file, like
default menu.c32
prompt 0
menu title Multiboot USB
timeout 100
label Multiboot USB
menu label Multiboot USB
kernel /grub.exe
6. Install Syslinux
sudo blkid ### tells drives and partitions
sudo dd bs=440 count=1 if=/usr/lib/syslinux/mbr.bin of=/dev/sdX ## where X=drive
7. Download, extract and copy grub4dos files grub.exe and menu.lst to the USB.
An example about menu.lst file
# menu.lst produced by grub4dosconfig-v1.8.0
color white/green yellow/blue white/black green/black
#splashimage=/splash.xpm
timeout 30
default 0
color white/blue blue/yellow white/black yellow/black
#color white/blue black/cyan white/black cyan/black
timeout 30
default 0
