Harvey Norman so you post to USA forum about a store in Australia? really>?
You purchased this 10 years ago right,if yes wow.
I went to Normans online no used PC there. so...

first off if you asked them for passwords this is now ILLEGALL by law spring 2018 , and your country is signatory on GDPR regulations I think, right? security key what does that mean?
my guess now is its asking for

HDD password locked
some have power on PW locks
then comes windows PW.
and and last , your windows activation code
lost.
not posting your failing screen photos makes this impossible to answer.

Try F9 during boot.. I doubt you repartitioned that small partition when you reformatted the main partition of the drive. Then again, the F9 function might not work anymore, even though the partition is still intact.. From Asus Support:
Using the Recovery Partition(on selected models)
1. Press < F9 > during bootup.
2. Press [Enter] to select Windows Setup [EMS Enabled].
3. Select the language you want to recover and click Next.
4. Read the ASUS Preload Wizard messages and click Next.
5. Select a partition option and click Next. Partition options:
Recover Windows to first partition only.
This option deletes only the first partition and allows you to keep other partitions, and to create a new system partition as drive "C".
Recover Windows to entire HD.
This option deletes all partitions from your hard disk drive and creates a new system partition as drive "C".
Recover Windows to entire HD with two partitions.
This option deletes all partitions from your hard drive and creates two new partitions "C" (25%) and "D" (75%).
6. Follow the onscreen instructions to complete the recovery process.

Since there are several windows versions available for this laptop, you can download the correct drivers from here: http://support.asus.com/download/options.aspx?SLanguage=en&type=1

Make sure to burn off your recovery DVDs as soon as you get you rsystem back up and running so that you have them in an emergency.

Run the Check Disk Utility if the operating system is loaded.

To run the check disk utility you will need a repair disc ora operating system disc. Put the disc in the cd drive and boot fromit. You want to get to the Dos Command Prompt (Black screen with whiteletters) and type the following command: chkdsk /r
Check disk will run well over an hour or two and you will notice thepercentages going from high to low, this is normal. Let it run tocompletion. Then reboot machine.

If check disk fails to solve your problem you might have to reinstall windows.Try doing a Repair Install that way you don't loose your data, documents,music, pictures, videos or programs.

In windows xp you get to the dos command prompt by selecting R for repair whenthe options appear.

In Vista and Windows 7 you want to get to the recoveryconsole and look down at the bottom of the window for the Dos Command.

Hello.. It is Very Possible that you have what is called a 'RECOVERY PARTITION', which has the rerecovery disk information installed on your Hard Drive. This eliminates having to use a CD.
