UBCD is, as its name indicates a CD that has the distinction of being bootable. Bootable means that we can start the computer and access their content without the need for an operating system (OS in English or abstract) such as Windows or Linux. This is particularly interesting for computers that are down or have not yet installed system.
UBCD contains a large amount of tools (all free) to deal with a very large number of situations or breakdowns. It is an ideal tool for troubleshooting a computer with the OS that does not start or to prepare a computer that will receive an operating system.
The latest version of UBCD can be downloaded from the official site: Ultimate Boot CD
