This ntbootdisk is a slightly modified version of the ntbootdisk by Petter Nordahl-Hagen, available at
http://home.eunet.no/~pnordahl/ntpasswd/bootdisk.html
You can use the NT bootdisk to change the password of any local user password in Windows NT/2000/XP. Ever wondered it would be nice to backup the SAM and restore the SAM file in case something goes wrong.
Imagine a situation where you have a login problem with a particular local user account but would like to login into the account without changing the user password. Well not a classic case but believe me there are situations where you want to backup the old administrator password, replace it and then restore the old administrator password or for that matter any other local user account.
Since the NT bootdisk loads the NTFS drive in read write mode, modify the scripts to store the SAM on a disk, proceed with the usual password replacement offered by Petter's chntpw. When the user would like to replace the old password back just copy it over and write the changes back to the NTFS disk. (eeeeh... doesn't it remind you of the good old days when you could replace PWL files to get into Win9x !!!!)
Think of this as a backup/restore for SAM.
Usage: You need TWO floppy disks one for the NTBootDisk and one for the SAM backup. Just boot with the NTBootDisk, when the menu appears enter 1 for backup and insert an empty floppy. If space is available on the inserted disk the SAM will be backed up on the floppy. The menu will return and you can choose to run the chntpw utility. If you decide to restore the old SAM reboot with the ntbootdisk and choose option 4 at the menu for restore. Insert the floppy that contains the SAM and restore should be complete.
Note: Petter Nordahl's ntbootdisk with the old version of the NTFS drivers works well for me on most machines hence I have modified that version rather than the latest one.
Download: Here is a binary image of the modified ntbootdisk (1.4 MB). Use rawwritewin to write the binary image to a floppy disk.
