Personally, I prefer one of
# shred /dev/hda # you'll wipe Win-DoS too if installed
# dd if=/dev/zero of=/dev/hda
# dd if=/dev/urandom of=/dev/hda
to really scrub the hard disk clean, but they can take quite a bit of
time with large disks. They really get rid of your data (especially
when using shred, see `man shred`) which is usually a good idea when
you plan to junk/sell/give away your machine.
If you want to keep Win-DoS, just loop over the /dev/hda* devices that
you want to clear and skip the ones you want to keep.

You can do that during the reinstall. Just switch to the second
virtual terminal with ALT+F2 and you have a shell where you can do
these basic things directly or go down the installer's menu to (re)
partition the hard disk.

Sometimes it's easier to just reinstall the whole bunch (although you
may want to keep /home -> put it on a separate partition to do that!).
It's probably also a good idea to backup /etc before going ahead. It
may come in handy later when (re)configuring stuff.
