The method is utilized in a computer system (10) having a first storage device (103) storing the first operating system (30) and a second storage device (11) storing a second operating system (33). The method includes: receiving a signal from the second storage device (11); detecting whether the second storage device (11) is a target device; setting the second storage device (11) as a booting device; rebooting; and executing the second operating system (33) from the second storage device (11).
