I have an HP Probook 4540s and cannot reset the password. I tried to reboot it with the shift key down to get to advanced options to try to enter DOS command mode so I could enter some reset commands, but it keeps coming back to the main user screen. Since there is only one user and no other admin account, I can't get in.

 

So I downloaded Ophcrack LiveCD (no tables) and burned the ISO to a disk. I changed the BIOS so the machine would boot from the CD, but it won't recognize it as bootable.

 

So I assumed that the ISO would make it bootable but it doesn't. How can I get the CD to become bootable with the Ophcrack ISO? And does anyone know if version 3.6 LiveCD is going to work with Windows 8? I can't find a specific Windows 8 download.

 

Otherwise, if anyone has a better way for me to reset the pw or get rid of it so I can enter a new one, I'd really appreciate it! I hate Windows 8, just might go back to Windows 7, to avoid this mess again!

 

Thanks in advance, guys!

Hello, and Welcome

 

Make sure Secure Boot and Fastboot are disabled in BIOS if they are enabled. Also set the BIOS to legacy boot from UEFI. Then change it back after you have done your work.

 

Another option is to create a bootable UEFI enabled flash drive with the OPhcrack iso. You would also need to disable fast-boot using a bootable flash drive. See this guide (option 1). Point it to the iso you downloaded. I like this utility instead. It will allow you to enable the hidden Administrator Account. Through that, you can reset the other account. You can also use Rufus to create a bootable Flash Drive.

Thanks John C. Someone else recommended the NT Password Reset tool at Pogostick, so I downloaded it to a flash drive. On the website it explains how to make the flash drive bootable and provides that file, as well. It worked great after that. Highly recommended, was easy to use. Got it done!

It means there is no tables folder on the root of your CD.

I think you would have a better chance enabling the hidden Administrator Account in 8.1 and using it to login.

Thanks for sharing. The above methods works fine. Actually, already got the problem solved with this password reset tutorial. It is a great alternative to Ophcrack. and it is user friendly for beginners.
