The Ultimate Boot CD is a bootable CD that contains tools for your computer's BIOS and CPU, Boot Management, Data Recovery, Device Info and Management, Diagnosis, Disk Cloning, Disk Editing, Disk Wiping, Installation, Partition Management, Memory. Because it has its own operating system, you can use it even if Windows does not start. The provided tools are extremely powerful, but not very easy to use. The interface is rather rudimentary and can be confusing. Due to the nature of the tools, the Ultimate Boot CD was created for the more advanced user. Also keep in mind that none of the tools can be used within the Windows environment. If you don't know how to change the BIOS/UEFI settings in order to boot your PC from a CD, you'd better stay away from it.
