Problem:
Usually you will test a new program once in a while. If this new program contains a virus (or maybe even a grave programming error), this can mean a lot of trouble for you.
Solution using the bootmanager BootStar:
You can solve this problem in a similar way as the Internet problem: You simply install another operating system for testing the new software.
If you find a virus, you can normally eliminate it fast and easily with the data security/backup solution.
Whether you just want to try out a new program or want to use your computer "normally", you can choose either option easily from a menu during booting. In order to change your selection, all you have to do is restart your computer.

The realization of the above listed application example is depicted in the following graphic:
X : Partition is visible
A : Partition visible and active (booting from this partition).
¹ : The both partitionen could, but don't have to be, get the same type
