The Scenario

My computer is Lenovo G50 with Windows 10. It got stuck in boot loop after my windows was updated yesterday. It has a black screen with an error message saying: Install Windows. Windows could not complete the installation. To install Windows on this computer, restart the installation. When pressing OK or X boots and repeats the error message. I could get into the Windows 10 Boot menu by pressing the reset button. I tried to start in Safe Mode, but an error occurred: Can't install Windows in Safe Mode. Any help would be appreciated, thanks.

Why is Lenovo stuck in boot loop?

A Windows boot loop occurs when the system repeatedly restarts itself during the boot process, typically due to an issue that prevents the operating system from loading properly. This can happen when Windows is trying to update itself and encounters a problem, or when there's a hardware issue that's causing the system to crash. As a result, the machine gets stuck in a loop, unable to complete the boot process and display the login screen.

▶ Possible reasons for PC stuck in the boot loop:

🕷 Bad Windows updates	Installing a defective Windows update can cause a computer to slow down.
🐞Malicious drivers	Sometimes malicious drivers are deployed.
📝Unverified driver signatures	To resolve this issue, you can try updating your drivers from the manufacturer's website or using a third-party driver update tool. This should help ensure that all your drivers have the necessary digital signatures.
📎Corrupt Master Boot Record entries	Corrupt registry or system files can prevent the PC firmware from accessing the Master Boot Record (MBR), which is necessary for the PC to boot up properly.
📸Slow lock screen/screensaver response	The lockscreen and/or screensaver may be interfering with the login screen from loading, preventing it from appearing.
☹Unwanted applications and Windows services in the launch sequence	Unwanted programs in the Windows starting sequence can sometimes cause a bottleneck.
🗂Too many startup apps	To resolve this issue, you can disable or remove unnecessary startup programs to free up system resources and improve boot time. This can be done by navigating to the Task Manager, clicking on the "Startup" tab, and selecting the programs you want to disable or remove.
🛠Applications that are tough to remove	Complex programs and apps, such as certain antiviruses, can cause delayed boot times due to their resource-intensive nature.
