The master boot record is required to boot your computer. Having a current backup of your master boot record is an excellent way to ensure that, in the event of a virus or hardware failure, you will be able to recover your system in the shortest amount of time possible.
After the Power on Self Test (POST) is complete, the system BIOS loads the first sector of the hard disk drive into memory and transfers execution to the code that was at that location. That code reads the partition table to locate the system partition and, after finding it, reads in the first sector within that partition (the boot sector) and transfers execution to it. That code contains the information necessary to start the operating system.
If for any reason, a link in the boot sequence is broken, the system will fail to start. A backup copy of the boot sector is already stored on the hard disk but a backup copy of the master boot record is not.
If you have saved a copy of your master boot record, you will be able to replace this critical sector of your hard disk drive and get the system back in operation quickly.
By following the solution listed below you will be able to successfully back up your master boot record to a floppy disk. With that file and Norton Disk Edit, you will be able to restore your back up copy to the hard disk in the event of corruption because of a virus or malfunctioning hard disk hardware.
