Hey there,

So I was cleaning my pc by going back to the original state and when finished I created a new password. However I was a bit drunk and probably misspelled it. However after many tries I gave up and searched for other solutions. This lead me to Ophcrack which I downloaded on a DVD and tried to run. But it gave an error about not finding the requested table(s). Now after a lot of tries with other programs and bootable USB's etc. it just won't work. Can anybody help me with this issue? I've got an Windows 7 64x OS.

Starting script: ophcrack-launcher.sh
Searching tables in: /media/sdc1/tables
Tables found:
	/media/sdc/tables/vista_free/table0.bin

List of Windows partitions containing hashes:
	0. /media/sda2/WINDOWS/System32/config
    1. /media/sda4/Windows/System32/config
    
Select the partition to crack: 0
Starting Ophcrack
4 hashes have been found in the encrypted SAM found in /media/sda2/WINDOWS/System32/config/.

Did not find the requested table(s) /media/sdc1/tables/vista_free/table0.bin.

The passwords have been saved in /tmp/ophcrack.txt

Press ENTER to continue...

My console log

 

Hope somebody can help me!

If you need more information ask me!

 

Regards,

Rover

 

PS. English is not my foreign language and i've typed the console log so there may be type mistakes.

Don't use Ophcrack. Use the offline NT and password registry editor to reset your password or enable the hidden administrator account.

You can make a bootable disk or use Rufus to create a bootable flash drive from the iso file.

Thanks for the advice! However i get stuck at the point where it says "booting the kernel" and then it doesn't react anymore. How do I go further with this?

I'm reading things about that it might have to do with the EUFI or something? It's definitely in my pc (whatever it is), because it's all over the bios. I've got here a post about someone using linux to get a cmd before the password  (I believe).

Is this also able with windows 7?

The utility is linux based and your computer may not be compatible with the kernel. You may need to try an earlier version of the utility.

 

There is another way to enable the Hidden Administrator Account. It involves editing the registry so be careful. 

 

You are going to need a Windows 7 install disk or a Windows 7 System Repair Disk may work.

Dear John, 

 

Thanks for helping! The older version of Offline NT did the job and I'm back in my pc again! Really appreciate your thinking.

 

The best,

Rover
