Running Ubuntu from CD

[Jared Buck]

All ya gotta do is burn the .iso directly to the disc, you don't need to
extract the files on the disc and then burn them (as a poster here said
earlier).  Different types of CD media burn at different speeds.  Sometimes
CD media can be very very fussy about what speed you burn whatever you want
to them.

You first should probably do a checksum on the CD iso, all the isos come
with their own MD5SUM files.  On Linux it is very easy to compare the
checksums, just run "md5sum <isoname.iso>" and compare the value produced by
that with the MD5SUM that comes with the CD iso.  If you're on windows it's
a bit harder, you'll have to download a checksumming program for Windows in
order to do the comparison - just Google for that and you should be able to
produce some hits.

If the checksum on your iso appears different than the one provided in the
file that comes with the iso, your download is corrupted. That's why most of
us here download Ubuntu .isos using Bittorrent.  Bittorrent allows you to
grab all of the file from different people who have copies of the same file,
and it automatically will discard any parts that download corrupted
(downloading corrupted parts again until it gets a "clean" download)/  It's
a pretty fool-proof way to ensure that what you get will not be corrupted in
any way.
