It turns out that there's an even better way to install all versions of
Ubuntu, including 13.10, using a USB stick. It's easy, doesn't affect
any existing files on the USB drive, and offers maximum flexibility at
boot using grub. In my opinion it should be the first and foremost
recommended installation method. Here's what I just did to install saucy
on my previous raring machine:
1. Run the following command as root. This will install the bootloader
and create a /boot/grub directory on the drive, but won't touch any
other files. Very little space is required.
grub-install --no-floppy --boot-
directory=/media/$USER/$DISK_NAME/boot /dev/$DISK_DEVICE
2. Copy the Ubuntu installation ISO to a location of your choice on the
USB drive, for instance /isos. If you want to be able to boot other
versions of Ubuntu from the same drive, copy the corresponding ISOs as
well.
3. Create a /boot/grub/grub.cfg file on the drive, containing a
menuentry like the following for each ISO you want to boot:
set timeout=10
set default=0
menuentry "Ubuntu 13.10 Saucy amd64" {
set iso=/isos/ubuntu-13.10-desktop-amd64.iso
loopback loop $iso
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$iso splash --
initrd (loop)/casper/initrd.lz
}
(If you have only one menuentry, you may want to set the timeout to 1-3
or even 0.)
That's it, you can now boot from the USB stick. This was much cleaner
than the usb-creator-gtk tool, which unpacked the ISO into the USB
drive's root directory. It also segfaulted about 5 times before
successfully completing, while this method worked on the first attempt
:)
