I am using Ubuntu 10.04. I have created the Ubuntu ISO image on a 2GB USB drive. I want to add this USB drive as a boot option in the grub menu.

As per the manual https://help.ubuntu.com/community/BootFromUSB, there is supposed to be a /boot/grub/menu.lst file where I can edit the menu to add my USB drive as a possible boot option

But I don't see the menu.lst file

Can anybody suggest how to add my USB drive as a boot option in the grub menu?

As it turned out that I didn't need to add my USB as a boot option in grub menu. I was not being able to track the BIOS Setup Utility for the make of my machine and hence setting the boot order. Since I have figured out setting up the boot order using the BIOS setup utility (Press F9, in my case), I am closing this question and marking as solved.

menu.lst was from GRUB legacy. You might add the entry to 40_custom instead. –  minerz029 Oct 16 '13 at 0:05
how to do that? where is 40_custom located ? –  somnathchakrabarti Oct 16 '13 at 0:08
Boot from the USB flash drive directly using your BIOS. Why would you want Grub to load the Syslinux bootloader from the USB drive in the first place? It does not make any sense to me on what you're trying to achieve here. Please edit your question to include these details. –  gertvdijk Oct 16 '13 at 0:09
Please don't add answers/solutions in the question itself. Instead, use the answer section for that. –  gertvdijk Oct 16 '13 at 0:45
