Ultimate Boot CD is a collection of over 100 different programs packaged together into a program call Ultimate Boot CD

You just need to create a bootable CD with the Ultimate Boot CD ISO you can download from the website and then boot your PC from the CD.
The most useful program that I have found on it is for Disk Wiping and it's called Darik's Boot and Nuke (DBAN). You can use this programs to fully erase a disk by writing over every single bit on the disk multiple times. You can choose which wipe method to use as well as you can use the command "Autonuke" to quickly start erasing using the defaults.
