the processor.

1998—Master Boot Record
has been lost

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.
Invalid Electronic Serial
Number

corrupted.
Run Computer Setup. If Setup already has data in the
field or will not allow the serial number to be entered,
download from http://www.hp.com
and run

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