Reset Windows Password with Encrypted Drive


This is a quick how-to for resetting your Windows password, while still knowing your disk encryption password via TrueCrypt.

Most, if not all, password reset options for windows, will not work if your hard drive is encrypted with Bitlocker/TrueCrypt.

You will need a USB flash drive or CD-R, and Hiren’s BootCD. Get it here http://www.hirensbootcd.org/download/

Once your USB drive is bootable with Hiren’s, boot up from the flash drive and select Mini XP from the Hiren’s boot menu.

  • In the bottom right in the taskbar, there is an icon called “Hiren’s BootCD Program Launcher”, Click it.
  • Go to the Security / Encryption > TrueCrypt menu
  • Click Select Device, and click your hard drive. It should be the C: drive.
  • Select a drive letter, and click Mount.
  • Click Mount Options
  • Check the box that reads “Mount partition using system encryption without pre-boot authentication”
  • Enter drive encryption password.
  • Your hard drive will now be mounted as a new drive letter (temporarily)
  • Go back to the Program Launcher, Passwords / Keys > Windows Login > NTPWEdit (Reset Xp/Vista/7 User Password)
  • The NTPWedit will open with a default path to SAM file of C:\WINDOWS\SYSTEM32\CONFIG\SAM
  • Change drive letter from C to whichever drive letter you selected to mount to, and click (Re)open.
  • Your user names will be listed.
  • Click your username, and Change Password.
  • Set the new password, and Save Changes and Exit.

Reboot and login with the new password.

    • I haven’t used Bitlocker. I don’t believe Hiren’s BootCD has Bitlocker in it. There are other bootable cd’s that might, and some let you add your own software to it. That would be your best bet.

  4. I was curious if you ever thought of changing the page layout of your site?

    Its very well written; I love what youve got to say.
    But maybe you could a little more in the way of content so people could connect with it better.
    Youve got an awful lot of text for only having one
    or 2 images. Maybe you could space it out better?
