conditions are true:
• MBR Security is enabled.
• A backup copy of the MBR has been 
previously saved.
• The current bootable disk is the same disk 
from which the backup copy of the MBR 
was saved.

MBR after a disk utility or the operating 
system has modified the MBR may cause 
the data on the disk to become 
inaccessible. Only restore a previously 
saved MBR if you are confident that the 
current bootable disk’s MBR has been 
corrupted or infected with a virus.
