Operating system selection at boot time consequently depends on the bootloader configured within the primary partition that has the boot or "active" flag set on its partition table entry, which could be a bootloader of DOS, OS/2, eComStation, ArcaOS [4] or BSD, in addition to Linux or Windows. With the boot flag set on the Windows primary, the ...
