You are right. My spelling is a typo that slipped through.

Not all distros will work with Unetbootin, but most will. I am not sure why this
is the case.

You can install it as an application or decompress the tar and make the
Unetbootin file executable. It is small enough that you can use it as it is.

Unetbootin allows you to use a pre-downloaded ISO or to download one from a
list. This second option obviously takes longer and if you have the ISO (I
collect them) then it is the way to go. It takes only a minute or two to re-use
the usb key. It is advisable to delete the files on the usb key before you
launch Unetbootin as there is no built in formatting tool and it will overwrite
files with the same name. Otherwise write around them which can make your key
shrink in size over time as not all files are the same and files not
over-written will simply stay on the key until you remove them. Also you need to
mount the key before you launch Unetbootin or your key will not be available.

It is a very handy tool and the first thing that I go to when installing a new
distro. Also saving ISOs is very handy as opposed to cluttering your space with
CDs or DVDs. It gets my vote as the best utility for its simplicity and ease of
use. I have a box of bootable CDs and DVDs of Linux distros which goes back 7 or
8 years. There are dozens of spindles. I don't know what to do with them. They
are too good for landfill and a waste of space in my basement. Someday I will
install Mandrake 7 or Fedora Core 1, just to see what it was like.
