I'm making a bootable USB key for myself, and one function of it is to install Ubuntu.

I have downloaded the ubuntu-11.10-desktop-i386.iso file.

There is a pretty good method for installation of Red Hat from a USB drive, but the problem is, when it comes to Ubuntu, what the syslinux.cfg file should be?

I used syslinux -d /boot/syslinux /dev/sdb1 and put vmlinuz and initrd.img inside it.

Is the following item of syslinux.cfg correct?

LABEL InstallUbuntu
MENU LABEL Ubuntu 11.10 Install
KERNEL /boot/syslinux/vmlinuz
APPEND linux load_ramdisk=1 initrd=/boot/syslinux/initrd.img method=hd:sdb1:/

    Can you expand your question as to why you are not following the recommended installation method in step 2 ubuntu.com/download/ubuntu/download – fossfreedom Jan 22 '12 at 11:42
  • @fossfreedom Because I want my usb key can also boot with other linux distributions, such as Parted Magic, Lucid Puppy. – NGY Jan 22 '12 at 12:03
  • actually i had grub installed on my Kingston USB key , syslinux is kinda obsolete on my side – daisy Jan 22 '12 at 12:21
  • @warl0ck It's true, grub is much easier, maybe I should try it next time. – NGY Jan 22 '12 at 12:54

I have solved the problem using

LABEL InstallUbuntu
MENU LABEL Ubuntu 11.10 Install
LINUX /vmlinuz
INITRD /initrd.lz
APPEND boot=casper iso-scan/filename=/ubuntu-11.10-desktop-i386.iso

Here is the source for the information that helped me.


Hmmm....dude, you have chosen a very longer way. What you all need is a program called "Live USB" Click HERE to get it!
