The scenario: At work I have to shred data on old PCs (not my main responsibility). What I do is I boot from the Live-CD, choose Try Ubuntu, open the terminal and
sudo shred -v -n10 /dev/sda. This way the whole thing takes about five minutes and then I let it run until my shift ends.
Sometimes I have over 20 PC's a day so I would like to skip the CD burning/changing. Also some of the DVD drives don't work. USB's aren't really a solution, I cannot request 25 USB sticks.
Is there a way to boot (not install, same thing like TRY UBUNTU WITHOUT INSTALLING) from network a.k.a. PXE? My vision is to setup a PXE server, connect it to a 24 port switch and attach the clients to the switch.
I managed to setup a PXE server to install Windows or Ubuntu, but what I really need is to be able to just boot the try-ubuntu-method over the network. Full install takes too long and is unnecessary.
