Lenovo IdeaPad Not Booting: Possible Reasons

An Operating System consists of various components that take the help of different hardware components to work flawlessly. However, an update can consist of some buggy software that can eventually break into the general working of the existing modules. As a result, the computer crashes and doesn’t boot up as it previously did. However, different hardware issues can also be the reason behind the problem, and we will discuss each solution in a detailed way.

How to Fix If Lenovo IdeaPad Not Booting After Update?

Fix 1: Run An Automatic Repair

Windows comes with an Automatic Repair option for its laptops, which comes quite handy in several ways. However, if your laptop cannot open the mode directly, you have to use an external Windows Installation Media Drive. Please look into this link, create a new Windows Installation Media, and follow the steps below.

  1. Keeping the laptop turned off, insert the pen drive and press the power button.
  2. Once the display turns on, press the F12 (or Fn + F12) key multiple times, select your bootable drive, and press enter.
  3. Once your laptop boots up and a new window appears, click on Repair your computer from the bottom left corner.
  4. When the new page appears, navigate to Troubleshoot > Advanced options Automatic Repair and wait for the system to repair itself.
  5. Once the repair is done, your laptop should boot up normally. However, if it doesn’t, head to the next steps below.

Fix 2: Repair The Boot Sector

A boot sector is the storage area that helps boot up the operating system and is a part of the hard drive itself. However, there are high chances that the Boot Sector or BCD gets corrupted, and your laptop will fail to start for obvious reasons. But, the good thing is that this memory area can be easily reset. But, this will also require the Windows Installation Media device. So, having that said and assuming you have the device with you, follow the next steps:

  1. Boot from the Installation Media and then click on Repair your computer.
  2. Now navigate to Troubleshoot > Advanced options Command Prompt and wait for the Command Prompt to appear.
  3. Now run these commands by typing them and pressing enter:
  • bootrec /fixmbr
  • bootrec /fixboot
  • bootrec /scanos
  • bootrec /rebuildbcd

4. Once the commands are successfully executed, restart your laptop and boot from your hard disk to see if everything is working.

Fix 3: Hard Restart Your Laptop

If none of the above solutions worked for you, the next thing you can do is to restart your laptop hard. However, a hard restart can cause data loss; hence, you have to keep the same in mind. Also, unplug any external devices, including the keyboard, mouse, headphones, etc.

Once your laptop is turned off, simply press the power button and then the Shift key. Now wait for some time and let your laptop boot up. However, if this does not work, follow the next steps.

Fix 4: Reset The BIOS Settings To Default

BIOS is the program that controls everything from selecting your boot device to booting up your laptop, selecting the options, and overclocking. However, sometimes we tend to tweak the BIOS by changing some settings, which can cause the laptop not to boot up. So, the best way to fix the issue is to reset your BIOS to the default settings, which can be done quite easily.

Here’s how to reset the BIOS:

  1. While your laptop is shut down, press the power button.
  2. Once the display turns on, press the F2 (or Fn + F2) key multiple times and wait for the BIOS menu to appear.
  3. Now look for the key mapping for Setup Defaults (mostly F9 or Fn + F9).
  4. Press the key or the combination of keys and agree to any popups.
  5. Restart your laptop by pressing the Save and Exit key (F10 or Fn + F10).

Fix 5: Reinstall Windows

Resetting the BIOS is supposed to fix your laptop as it defaults all the settings, which might be causing any errors. However, if that doesn’t help, the only way out is to reinstall Windows on your laptop. This is a very easy task as you will just have to follow the steps on the screen and you will be done.

Here’s how to reinstall Windows on your laptop:

  1. First and foremost, insert and select the Windows Installation Media from the Boot Device Menu.
  2. Once a new Window appears, click on Install Now.
  3. Now Accept the Terms and Conditions and click Next.
  4. Now click on Custom on the next screen and your disk drives will show up.
  5. Select all the existing partitions one by one and click on Delete.
  6. Once you are left with the Unallocated Space, select it and click Next.
  7. Your Windows installation will now start. Wait for the process to complete and follow the on-screen guides.


In this article, we have discussed various reasons and the solutions that are causing the problem with your Lenovo IdeaPad not booting up. Reinstalling Windows is the most helpful way out and will mostly fix the issue easily. However, if that also does not work, you will have to visit your nearest Lenovo service center. Having that said, visiting the service center is quite helpful as they can diagnose the issue more perfectly and come up with a much better solution for your laptop.
