It possible to install several operating systems on the same machine. This requires a boot manager which is able to handle the different boot sectors used by each operating system. The boot sectors can be handled in two ways:
- All the operating system are installed on the same partition and the boot manager controls which boot-sector to load.
- Each operating system are installed on their own primary partition and the boot manager controls which primary partition becomes the active one.
