A method starts and operates a computer with an operating system held on a replaceable storage medium. The method includes: checking the authenticity of the replaceable storage medium and/or checking a user's authority for executing the operating system held on the replaceable storage medium. The operating system held on the replaceable storage medium is executed if the replaceable storage medium is authentic and/or the user is authorized to use the operating system. Checking the authenticity of the replaceable storage medium and the user's use authority ensures the integrity of the operating system. Thereby, modifications to the operating system and to the computer are made more difficult. The invention also relates to a computer and a replaceable storage medium which are suitable for carrying out the method.
