hdd password recovery

howdy. if this isnt the right forum please move it.
a friend has a 3 year old hp or compaq tower. they called me to help. they are not able to get into the admin accound, because the password was changed. it was changed by them when a popup told them for security they should change thier password.
after it was changed they could no longer get into the admin account with the password they changed it to, and the computer started sending out emails to everyone on her address list with porn and viagara type adds.
i ran anti virus and we found 20 trogans, virus, ect. everything comes back clean now, but we still cant get into asdmin account to format drive.she doesnt have a vista system disc, just the recovery partition.
1.. is there a way to get the password?

2... if not can i install a new hdd and install from her recovery partition?

3...will i be able to install new hdd and install vist from my disc or is the mb set up to not alow that?

thanks for any help, they are on a limited budget and are true friends to me and i would like to help them. thanks! sam

You can reset your password following the next steps:

• Reboot your computer / Turn your computer on.
• Hold down the Shift key at the start of the boot process to enable the GNU GRUB boot menu (if it does not show)
• Press ESC at the GNU GRUB prompt.
• Press e for edit.
• Use the Arrow keys to highlight the line that begins with kernel and press the e key.
• Go to the very end of the line and add rw init=/bin/bash
• Press Enter and then press b to boot your system.
• Your system will boot up to a passwordless root shell.
• Type in passwd yourusername
• Set your new password.
• Restart your system.

 

Password Override and Recovery Key

I cannot seem to get past my sign in page. I use the password I thought I used, then try the Windows password. No luck getting on. First how can I override the password page? Secondly, I would like to eliminate use of password, how do I do this? It
was suggested to just reset to factory settings if it was a local setup. I can't seem to get to the recovery key, just keep getting to question/ answer page. Hlep. Thanks
