Windows Xp Logon Password Not Working

I created a logon password for my Windows XP logon but when I try to logon it doesn't recognize it. I tried to reinstall Windows XP on the other partition (D) without formatting but it stalled on the last 7 minutes so I aborted the installation. When I switched my PC back on it presented me with two windows XP to choose from. The first Windows XP will accept my logon password but I don't think it's loging on from the old Windows installation that I want to logon to because the image on the Admin account is different from the one where I created password for. Additionally, my desktop items and all programs are all gone. When I logon to the second Windows XP I get presented with the Admin logon screen and correct Admin user image but it doesn't accept the password. I am completely lost as to what exactly happened. My question is how can I disable the logon password or how can I get around this mess? Please help.

Please don't bother yourself attending to this as I already re-installed Windows XP to resolve the problem.
