Recommended Action
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 certain that the
MBR change is unintentional and
undesired (e.g. 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.
Run Computer Setup and either disable
MBR security or save the MBR of the
current bootable disk.
Run Computer Setup. If Setup already
has data in the field or will not allow the
serial number to be entered, download
from www.hp.com and run SP5572.EXE
(SNZERO.EXE).
Run Computer Setup and try to enter
serial number under Security, System ID,
then save changes.
Replace the memory module.

utilities.
