A software program for initiating the operation of a computer.

Because the computer gets itself up and going from an inert state, it could be said to lift itself up "by its own bootstraps" -- this is where the term [Boot] originates.
Other computer systems are also said to have a bootstrap. For example when writing a [Compiler] written in the ProgrammingLanguage that the [Compiler] compiles (think about it for a second), it is necessary to have either a CrossCompiler or a BootStrap -- a program written in a different language ([Assembler] in the worst case scenario) which can be used to compile a cut-down version of the [Compiler] initially. Of course, once even a bare-bones version of the new [Compiler] runs on the new platform it can be used to compile more sophisticated versions of the [Compiler]. Given the choice, cross-compilation is usually preferred.
