I tried this and I dont know, it doesn't work I guess. See attached. This step I click on CHANGE/RESET and then nothing happens. It hangs!
seems you got more issues than a password. Try making a bootable usb thumb drive, it might be your dvd/cd rom sucks.
No, its just the password. Just the password says incorrect, so all I need is to change the password. I already made this as bootable CD and did it. Not sure, whats wrong now.
I noticed that right away... try changing that to account disabled No account Locked No and change password to blank or set one
