HP Pavilion a1102n with Windows XP-recovery to original factory

[db_hp_owner]

I own a desktop HP Pavilion a1102n with Windows XP.  I would like to recover computer to original factory condition.  I don't have recovery disks, but I noticed the following instructions for using the Microsoft Management Console (for a laptop): 

1) Right click on "My Computer" and select "manage"

2) This will launch Microsoft Management Console

3) on left side of the MMC, click on "Disk Management" and it will show you all the partitions.

4) Right click on "HP Recovery" partition and select "Make as active partition

5) when warning prompt appears select "Yes"--Reboot the notebook and it will automatically boot into the recovery manager (without having to press F11). 

Are these the correct steps for my desktop computer?

Are there additional steps I need to follow?

Do I need to undo the step of making the HP Recovery the active partition?

You should be able to boot into Recovery Manager by tapping the F10 key immediately after powering on your machine.Or by using the shortcut in your Start,All Programs. You also have software to burn a Recovery DVD set.
