Note: This method works on all Lenovo Yoga series laptops that come with Windows 8.1 pre-installed, including Lenovo Yoga 2 Pro. Of course, you can also use PCUnlocker to bypass Windows 8.1 passwords on HP, Dell, Sony, Toshiba, Acer and other laptops or tablets.

How to Bypass Windows 8.1 Password on Lenovo Yoga Laptop?

Before getting started, you need to make a PCUnlocker Live CD on an alternate computer. Download the zipped ISO image of PCUnlocker and extract it. Next burn the resulting pcunlocker.iso file to a blank CD (or USB stick) using the ISO2Disc program.

Put the CD in the CD drive of your Lenovo Yoga laptop. To get the laptop to boot from CD, we need to go into the BIOS and switch the Boot Mode from Unified Extensible Firmware Interface (UEFI) to Compatibility Support Mode (CSM). When the computer is off, press the Novo button and then select BIOS Setup.

In the BIOS Setup Utility, go to Security tab, and disable the Secure Boot option. Next, on the Boot tab, change the Boot Mode from UEFI to Legacy Support. Save the changes and exit BIOS. Shut down the laptop and then press the Novo button again and then choose Boot Menu. Choose to boot from PCUnlocker Live CD.

The laptop will load the WinPE OS from CD and open up the PCUnlocker utility. At this point the program can directly access the Security Accounts Manager (SAM) database and extract all your Windows user accounts.

Select your user account and click on “Reset Password” button. The program will reset your forgotten password by modifying the stored password hashes in the SAM registry file. Restart the computer and take out the CD. You can then log back into your Lenovo Yoga Windows 8.1 laptop with a blank password!

Conclusion

The advantage of this method is that it is very quick if you already have the PCUnlocker Live CD in your tool box. Thus it is useful for admins who have to perform this procedure often.

The reason behind this is, most of Windows 8/8.1 laptop is configured in UEFI mode (Unified Extensible Firmware Interface). The UEFI mode does not allow to boot legacy OS like Windows XP, DOS etc. So to reset Windows 8/8.1 password, the conventional method does not work.

Luckily, the latest version of PCUnlocker came out that can boot in UEFI mode. This article will introduce how to make a PCUnlocker Live USB and then use it to bypass Windows 8/8.1 password on Toshiba Satellite laptop.

Create A PCUnlocker Live USB

If you can’t boot into your Toshiba Satellite Laptop, you’ll need to borrow one from a friend to make your own PCUnlocker Live USB drive, but other than that, all you really need is a USB flash drive. Here’s what you need to do:

1. Download the PCUnlocker Enterprise and save it on your spare computer. Please note both the Standard and Pro editions don’t support UEFI booting. The downloaded file is a self-extracting .zip file which contains a UEFI bootable ISO image: pcunlocker.iso. Extract the ISO image file from it.
2. Burn the ISO image file to your USB flash drive using the freeware ISO2Disc or Rufus. Make sure you choose the “GPT” or “GPT partition scheme for UEFI computer” option while burning the USB drive. If you don’t have a USB drive at hand, you can use a blank CD to make a PCUnlocker Live disc.

   

3. Once your USB drive has finished burning, insert it into your Toshiba Satellite laptop.
