After resetting the BIOS/UEFI Windows has stopped running

In this article, we consider the reasons why the system may fail to boot and a way to fix it. First of all, think about recent developments. Maybe you connected a new device that held a clean computer, installed a program or updated drivers? These changes may go by without your intervention. For example, Windows 10 automatically installs system updates and drivers without getting permission of the user.

Wrong BIOS setting

If after resetting the BIOS or UEFI operating system (OS) ceased to boot in this case, you must adjust the settings of BIOS or UEFI. In the startup process in most cases, a message appears Reboot and Select proper Boot device or Error: No boot disk has been detected or the disk has failed



First of all should pay attention to what device boots first. Of course it is necessary that the priority was standing hard disk with an installed OS on it. The most common problem in the operating system may cause the change of the operation mode of the hard disk: IDE, AHCI. Change the operating mode of the BIOS: Legacy, UEFI, CMS (Compatibility Support Module).

For the OS starting with Windows 7 and above, mostly used mode to ACHI. If it does not fit, you can alternately try the rest.



In the older versions of motherboards it is possible that when the SATA hard disk and in the settings Advanced — SATA Controller — disabled.

Reset the BIOS

Quite often, experienced users changing any settings in the BIOS are faced with the “problem” PC, and need to return everything to its previous state.

Fans to delve into the BIOS sometimes fall into such a situation that after changes to the BIOS settings something is not working as it should (or not working). If You are sure that a problem with the computer caused by changes in BIOS, the easiest solution to the problem will be reset the BIOS.

How to get into BIOS?

Usually, the button to enter BIOS menu write when turning on the computer/laptop (try to restart your computer to see the first welcome screen). Often it is some kind of button: F2, F10, Esc, Del (99% of devices support these keys).

In some models (in particular, Lenovo), on the case there is a special button to enter the BIOS.

To reset the BIOS configuration it is necessary in the following cases:

  • If you need to reset the password to the BIOS (or the password on the continuation of the running OS);
  • If your computer is not stable;
  • If the computer does not boot the operating system;
  • If You changed configuration in the BIOS Setup, but not sure of the correct implementation of their actions.

Reset BIOS is to reset the contents of CMOS memory.

That’s about it. I hope that this article was able to help in solving the problem.
