However, as USB devices typically achieve lower data transfer rates than internal hard drives, booting from older computers that lack support for USB 2.0 or newer can be very slow.

Specialized USB-based booting was proposed by IBM in 2004 with Reincarnating PCs with Portable SoulPads and Boot Linux from a FireWire device. Intel-based Macs carried this functionality over with booting macOS from USB.

Most Live CDs are Linux-based, and in addition to repairing computers, these would occasionally be used in their own right as operating systems. The development of the first live CDs with graphical user interface made it feasible for non-technicians to repair malfunctioning computers. To repair a computer with booting issues, technicians often use lightweight operating systems on bootable media and a command-line interface.
