And another option (if you do not need to partition your harddrive, is
to boot from an ISO on the harddrive. GRUB2 supports directly booting
from and ISO file on the harddrive. This limits some of the
functionality (like installing it to a new partition, as you cannot
partition the drive while it is mounted and in use).
for more info on that:
This is a decent option if you want to try out various flavours, though
ones other than Ubuntu can be a bit harder to boot from an ISO, most of
them will boot pretty well just looking at the menuentry(I can't
remember the filename right now) in the ISO and adapting it....
You can boot an ISO on a USB from GRUB2, even if your BIOS wont
support booting from USB (though you can also install the live system to
the USB, and boot into that OS from GRUB2 as well)
These points are mainly to add to the discussion for people following
it... it may not really be the type of answer you are looking for... but
it can all be done from the grub command line too.
Also, Fedora has a script for writing live images to a USB. You could
(if you know BASH) adapt it to suit your needs, as it worked quite well
for me writing Korora to a USB (faster than unetbootin)
