Screen message Probable cause Recommended action
1998—Master Boot Record
has been lost
The previously saved copy of the MBR
has been corrupted.
Run Computer Setup and save the MBR of the current
bootable disk.
1998—Master Boot Record
has been changed
The current MBR does not match the
previously saved copy of the MBR.
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.

corrupted.
Run Computer Setup. If Setup already has data in the

Run Computer Setup and try to enter serial number
under Security, System ID, and save the changes.
