Decide which OS image to start

Bootloaders can usually load one of few kernel images that are known to the bootloader This can be done in embedded systems to make sure we can upgrade a kernel without fear of power loss during upgrade, since we always have a backup kernel that will load. In PC environments this is done to let the user choose among several OS's or give the user a chance to try another kernel without losing his/her current kernel.
