MBRWizard was designed to allow the user to reverse or repair these unwanted, destructive changes to the MBR, effectively enabling the computer to once again boot properly.
Initial functionality was designed to sort partition table entries caused by effects of disk imaging, but quickly evolved to include the backup and recovery of the entire MBR, repair of a corrupt Windows MBR record, as well as direct modification of the disk signature.
Later options were added to include disk wipe functionality, shutdown/reboot of the machine, mount/dismount of Windows volumes, and a staging byte utilized to maintain status between reboots.
Designed as a cross-platform application from the beginning, MBRWizard is noted as being very flexible as it can be implemented natively on most PC operating systems[citation needed].
