1. Install a program called chntpw $ sudo apt-get install chntpw 2. After successfully installing chntpw, you have to access the Windows NTFS partition by mounting it and allowing read/write support (see below) 3. After that, use your command line skills by navigating to WINDOWS/system32/config 4. Once inside the config directory, issue this command: $ sudo chntpw SAM 5. A long display of information will follow. Just ignore them. 6. Once you are prompted to reset the password, it is recommended to leave the password blank with an asterisk (*). 7. Reboot, and you can now login to Windows with full administrative access.
