Q: Windows 10 – Laptop won’t boot up after update
Yesterday I was going to turn off my laptop, I noticed there were upgrading options and I chose ‘update and turn off’ because it was getting late. Windows 10 updated with no errors at all, and there were no major issues during the update; when it was done, it turned off like it always did, and I unplugged the laptop from the power. However, when I woke up today, it just wouldn’t start; it would boot up, then it’d reach the ‘Loading’ screen with spinning circles, it would just get stuck there. The laptop wouldn’t freeze or just glitch and it’s been about this for seven or eight hours. How do I fix this?

In this part, we list 8 suggestions to help remove Windows 10 infinite loading issue. However, before you start, it is better for you to prepare a Windows 10 installation disc which is very helpful in the following content.

Are you ready? Let’s move on.

Fix 1: Perform a Startup Repair

The first thing we think you can have a try is to boot the computer into the recovery environment to perform a startup repair. And here are two ways for you do to so:

(1) With installation disc:

Set PC to boot from the installation disc and wait for Windows to load files. When you see the Windows Setup interface, select the language, time and currency format, keyboard or input method and click Next. In the next page, click “Repair your computer“.

Then follow this path: Troubleshoot -> Advanced options -> Start-up Repair. Finally, choose a target operating system and then Windows will start diagnosing your system. If any problem is detected, Startup Repair will attempt to fix.

(2) Without installation disc:

To access the recovery environment, turn your computer on and off for three times (make sure each time you turn off the computer when you see the Windows logo). After the third time, Windows 10 will boot into Diagnostics mode. Please click “Advanced options” when the Automatic Recovery screen appears.

Then follow this path: Troubleshoot -> Advanced options -> Startup Repair. Now you can choose a target operating system to repair and Windows will begin the diagnosing and try to fix startup problems.


Tip: Startup Repair also works for Non System Disk or Disk Error in Windows 10/8/7.

Fix 2: Repair Master Boot Record (MBR)

If the problem insists, you may consider whether the MBR is damaged due to malware infections or improper shutdowns. If this is the case, you can run the rebuild or repair MBR commands which do more than the “Rebuild MBR” feature of MiniTool Partition Wizard to fix Windows 10 infinite loading.

Step 1: Also, boot your PC from the installation disk and then follow this path: Repair your computer -> Troubleshoot -> Advanced options -> Command Prompt.

Step 2: Type in the following commands one by one and press Enter key after each of them.

  • bootrec /fixmbr
  • bootrec /fixboot
  • bootrec /rebuildbcd


Step 3: Exit and now go ahead to reboot your Windows 10.

Fix 3: Check and Fix Hard Drive

This suggestion is put forward by a user from, and it has been proved very useful by thousands of users. Please get ready for the world’s simplest fix to this issue.

Step 1: Follow the path in Fix 2 to get the command prompt window.

Step 2: From here run “chkdsk c: /r /x” without quotes and watch the magic work.

1. Simply running the CHKDSK command will only display the disk’s status. To tell CHKDSK to fix errors on the drive, we need to give it parameters. “/r” tells CHKDSK to locate the bad sectors on the drive and recover readable information and “/x” forces the drive to dismount before the process starts.
2. If CHKDSK only scans, you will need to run “sfc /scannow” and reboot. Windows 10 startup problems should be solved then!

Fix 4: Reset BIOS to Default

If you have recently made any change in BIOS and then started facing this problem, maybe you can fix Windows 10 not booting issue by reverting the change or resetting BIOS settings to default values.

Step 1: To open BIOS settings, you need to restart your computer and keep pressing F2 or F12, Delete or the similar based on the motherboard manufacturer.

Step 2: Once there, you are likely to see a key at the bottom that says F9 – Setup Defaults. Press this key and confirm with Yes to reset BIOS to default settings. On some machines, you may find this option under the Security tab and the option is named Restore Factory Defaults or Reset All Settings. So be sure to have a look around to find the right place.

Fix 5: Uninstall Windows Updates

Apart from the third-party drivers, an official Windows update can also break your system, making Windows 10 not booting after update. If you have recently installed any Windows Update and then the problem comes, you can start PC in Safe Mode and uninstall that update.

But how can you enter Windows 10 Safe Mode? Also two suggestions for you:

(1) With Windows installation disk:

Follow this path first: Repair your computer -> Troubleshoot -> Advanced options -> Command Prompt. Then in the command line window, type “bcdedit /set {default} safeboot minimal” without quotes and press Enter on your keyboard.

When the command is running successfully, close the command prompt and choose Continue. When your PC reboots, your Windows 10 will automatically enter into the Safe Mode.


(2) With Windows recovery drive:

Boot your computer with the USB recovery drive, select your keyboard layout and then choose Troubleshoot on the next screen. Then follow this path: Advanced options -> Startup Settings -> Restart.

Finally, press the 4 or the F4 key on your keyboard to boot into minimal “Safe Mode”, press 5 or F5 to boot into “Safe Mode with Networking,” or press 6 or F6 to go into “Safe Mode with Command Prompt.”

Then you should carefully select the problematic update and click theUninstallbutton. We kindly suggest you distinguishing the updates by observing the name and date.
