How to Fix Windows 11 Stuck on Startup after KB5043145 Update
Do you often find your laptop stuck on startup screen after KB5034145 update when you try to turn it on? When you start Windows 11, it hangs at the start logo for minutes or hours for no apparent reason. Some people assume forcing a shutdown might fix the issue temporarily. However, this approach is neither sustainable nor safe for your data or system stability. But don’t worry. This article will fully address the Windows 11 stuck on startup/boot/loading screen issue. In this post, we’ll look at the possible reasons and best treatments for the laptop stuck on startup screen after KB5034145 update issue.
Solution 1: Unplug All Peripherals and Reboot
A malfunctioning USB storage device may be the reason behind the Windows stuck on startup after KB5034145 update issue. In this situation, you should unplug all functional USB devices—such as Bluetooth, SD card readers, flash drives, wireless mouse dongles, and more—attached to your computer via USB cables.
Remember to restart the computer after unplugging the USB cords and gadgets. This way, your computer should boot up without any issues.
This approach should be able to solve your problem. However, try the following solutions if this method does not resolve the issue.
Solution 2: Reboot Laptop in Safe Mode
Windows updates or other issues might occasionally be the source of the Windows 11 stuck on loading screen issue. To make your computer start properly again, you may now enter Safe Mode, do nothing, and restart it. A minimal set of drivers, software, and services are installed before Safe Mode is activated. Safe Mode launches without issues when your computer is stuck on the boot screen and Windows cannot start normally. You’ll find it helpful to troubleshoot there.
-
To access Safe Mode when Windows 10 becomes stuck on the loading screen, you need to either start your computer from the bootable CD or restart it more than thrice in a row until the Preparing Automatic Repair screen appears.
-
After that, choose “Advance options” > “Troubleshoot” > “Advanced options” > “Startup Settings” > “Restart.”
-
To start your computer in Safe Mode, hit the 4 or F4 key on your keyboard.
Solution 3: Check & Repair System
You also have the option to create WinPE with 4DDiG Partition Manager to quickly fix laptop stuck on startup screen issue. Among the many robust features of this all-inclusive solution is the ability to generate a Bootable WinPE Media, which is necessary to access your system even if it cannot be booted. Furthermore, its capacity to fix damaged Master Boot Record (MBR) or EFI partitions—also referred to as repair boot—guarantees effective booting process restoration.
Follow these steps to create a bootable WinPE media using 4DDiG Partition Manager:
