Patent ID: 8667262

Claim:
An information processing apparatus provided with a processor and a main memory, comprising: a first recording medium that stores a first operating system performing control of the information processing apparatus that directs the processor to execute boot processing of the information processing apparatus, and is accessed by using a first access path in a tree structure or by using a second access path based on a first conversion table representing a correspondence between the first access path and the second access path; a virtual disk generation section that directs the processor to secure a virtual disk which is accessed by using a third access path in a tree structure and which is a predetermined storage area in the main memory; a conversion table generation section that directs the processor to generate a second conversion table representing a correspondence between the second access path and the third access path; a duplication controller that directs the processor to copy the first operating system onto the virtual disk as a second operating system and directs the processor to duplicate the first operating system and the second operating system based on the second conversion table; and a mount controller that directs the processor to associate the first access path and the third access path with the second access path based on the first conversion table or the second conversion table and, when receiving removal of the first recording medium, directs the processor to release the association between the first access path and the second access path to remove the first recoding medium.
