Sorry to dig up an old thread, but I'm having this exact same issue. the partition my windows install is on is the second one (1 being the boot), and windows was installed into the default path. I've tried 1 and 2 but either way it still asks me where the default registry directory is at. I can't get past this step anyone have any ideas?
Some general tips.
This tool DELETES the password. It does not RECOVERS the password. So if you have some encryption software, eventually you will still need to enter the correct password to get to your data. Some laptops and systems alike have encryption installed without the user even knowing it. If you don't use encryption, then deleting the password should give you access to Windows so you can set a new one.
For Windows Seven, the "Windows" partition is usually number 2
This is usually the problem with users not reading the complete screen with command line tools.
I can't know if this is your case, but let me ask you; after accepting the default registry path, what did you do?
You should select the correct option to "Edit user data and passwords" (option 1, <enter>).
After that, you need to type in the correct exact user name (with the same lower or upper cases). If the user name is the default for that step, simply press <enter>.
Select option "1" to clear (blank) user password.
If there are no errors, then you should see a message like "Password Cleared!".
Now type "!" (without quotation marks) so to quit this part of the process
Please do not reset your system YET. You are NOT FINISHED!!!
In the previous step you used "!" to quit only "a part" of the process. Now you need to press "q" (without quotation marks) to quit.
NOW it asks "Step FOUR - writing back changes". You need to type "y" so to actually right the changes
The additional tip I can tell you is, be patient. As with the OP, sometimes it just takes a little bit more time.
If you still can't find your correct Windows registry path, you may use PMagic in UBCD to find the correct drive "number" and the correct Windows Registry path for the correct "User name".
Are you seeing the "EDIT COMPLETE" message?
If you do, and you think that everything was done correctly, then press "n" <enter> so to finish the program.
Only NOW take out your CD and reset your system. When you get into your Windows account, go and set a new password.
I apologize if something of my message sounds somehow "rude" to someone. It is not my intention at all. I just know that many users that fail to correctly reset their passwords with this tool are actually failing just because they don't get to the end of the process (they don't read the instructions).
