Try using Ophcrack to get his password. All you have to do is this:
1. Put the disk in while it is booting up.
2. Turn off computer.
3. Turn back on.
4. Enter BIOS (often f1 or DEL)
5. Click the 'Boot' option and have it boot from your cd drive first.
6. When Ophcrack loads use the arrow keys to click the top option Graphics mode
Vwalla! Let it do its stuff and there you go! You get your password back. It can crack passwords 14 characters or less. It normally does the cracking under five minutes.
Now, the harder part, getting ophcrack. 1st ophcrack is legal so don't worry (as long as you only use it on your computer). And 2nd its FREE!!! All you need is a cd burner and a computer ( that you are not locked out of). Go here to download Ophcrack Live CD.ISO.
http://sourceforge.net/project/downloading.php?group_id=133599&use_mirror=easynews&filename=ophcrack-livecd-1.2.1.iso&40965952And, when you download Ophcrack, leave it in its WINRAR archive (just don't touch/extract it exept to move it to a folder or something). Go here to download a free software that makes burning .iso images easy. ---IMPORTANT, DON'T USE YOUR NORMAL BURNING WAY!!! YOU HAVE TO BURN THE ISO IMAGE NOT THE FILE!!!---
http://www.dvddecrypter.org.uk/Just click on Get DVD Decrypter
Then when you have downloaded both of these, install dvd Decrypter. Once you have open it up, click Mode on the top tool bar, click the bottom ISO and then click Write W.
Now just Choose your destination (your cd burner with a blank cd) and choose which file you want to write ( It will have a thing that says please select a file). Then click the Hard drive to disc picture that says click to write and your done!!!
If you have trouble understanding this please say so, it can be a bit confusing.
