  • SAM is the file that contains the Windows registry. The list of users on your system is displayed. Enter the code located in the RID column beside the name of the user you want to reset the password to zero code preceded by 0x and press Enter. For RID 03E8, the command becomes 0x03e8 here.

cd...if u r using a cd then simply  download the iso and burn it in the cd and use it

usb...

  • Copy all the files that is inside the usbXXXXXX.zip or on the CD onto an usb drive, directly on the drive, not inside any directory/folder.

  • It is OK if there are other files on the USB drive from before, they will not be removed.

  • Install bootloader on the USB drive, from command prompt in windows (start the command line with "run as administrator" if possible)Replace X: with the drive letter the USB drive shows up as (DO NOT USE C:)

    • X:syslinux.exe -ma X:




  • If it seems like nothing happened, it is usually done.

  • However, a file named ldlinux.sys may appear on the USB drive, that is normal.

  • It should now in theory be bootable.


now use the cd or usb to reset the password use the walkthrough if needed http://pogostick.net/~pnh/ntpasswd/
