Boot Agent Problem for laptop?

I went to turn on my laptop (it used to be my dad's work laptop) and it is encountering problems try to boot up.



The very first screen that I encounter when trying to boot my laptop says:



';ERROR

2100: HDD0 (Hard Disk Drive) initialization error (2)

Press %26lt;Esc%26gt; to continue';

When i press escape, it leads to





';Intel(R) Boot Agent GE v1.2.50. Copyright (c) 1997-2007, Intel corporation.

Intel(R) Boot Agent PXE Base Code (PXE-2.1 build 086)

Copyright ? 1997-2007, Intel Corporation”

and ';Initializing and establishing link ...';.



And then after a minute or so: ';PXE-061: Media test failure.'; and ';PXE-M0F: Exiting Intel Boot Agent.';



It then takes me to a screen that says:

“

As of right now, the ';current boot order and device status'; is:

1. USB FDD -%26gt; Device not found

2. ATAPI CD0: ModelMATSHITADVD-RAM UJ-842-(PM) -%26gt; No valid operating system

3. USB CD: -%26gt; Device not found

4. ATA HDD0:

5. PCI LAN: Model IBA GE Slot 0200 v1250 -%26gt;No valid operating system

6. -USB HDD -%26gt; Device not found

7. ATA HDD1: -%26gt; Device not found



Excluded from boot order:

: ATA HDD2:

: ATAPI CD1:

”



I here that this problem probably arose from it trying to boot from a network drive and that I should change my boot priority order?



Does anyone have any idea what I the problem is and how I can fix it? Thanks so much for the help.Boot Agent Problem for laptop?
This suggests, ';Excluded from boot order: : ATA HDD2';, that either the drive has gone bad, or the cables may not be secure.
