Master boot record

Master boot record is the first physical sector of a boot device (floppy, hard disk, or CD-ROM, etc.) During the process of booting up the system uses the master boot record of the first device. It usually contains a small program-loader and a disk partition table. The program-loader uses the partition information (or a partition table) stored at the end of the sector to determine which partition is bootable, then attempts to boot from it.

Testimonials and User Comments

In need of an imaging program for Windows 7, on a whim I tried out Acronis True Image 2010; the speed, integration with the OS, and ease-of-use made me a convert even after being a dedicated Norton user for 13 years!
