The current MBR does not match the

Use extreme caution. The MBR might have been
updated due to normal disk maintenance activities (disk
manager, fdisk, or format). Replacing the previously
saved MBR in such situations can cause data loss. If
certain that the MBR change is unintentional and
undesired (for example, due to a virus), run Computer
Setup and restore the previously saved MBR copy.
Otherwise, run Computer Setup and either disable
MBR security or save the MBR of the current bootable
disk.
