1L* The current MBR
does not match the
previously saved copy
of the MBR.
Use extreme caution. The
MBR may 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 you are certain the MBR
change is unintentional and
undesired (e.g. due to a virus),
then run Computer Setup and
restore the previously saved
MBR copy. Otherwise, run
Computer Setup and either
disabled MBR security or
savethe MBR of the current
bootable disk.

bootable disk.
