Create PC Diagnostics Boot CD - auto scandisk, defrag, memtest

This project is to create an ISO CD-ROM image of a boot CD. The purpose of this CD is to automatically run general computer maintenance and diagnostics on any PC using existing freeware solutions. In short, this is a boot CD that will automatically run Scandisk, Defrag and MemTest; and then display the results with no user input. *I am aware that several boot CD's exist, such as Hiren's or Ultimate Boot CD. Those projects should be drawn from to complete this project. (You may use existing freeware/open source utilities in the design of this project). **This project differs from the others in that it will automatically run a series of tests on boot up and display the results and system information upon completion of that series of tests.
