An interesting page on Master Boot Record ( MBR ). Hard disks, MBRs and boot sectors, disk geometry, partition tables, and file systems are complex technical subjects. The information in this web page is intended for beginners and should be sufficiently accurate to explain what's happening to someone who wants to install Ubuntu in a computer, and dual boot with some other operating system. It is beyond the scope of this web page to be technically correct to anyone who takes the subject seriously, for example, anyone studying computer science.
