Sometimes it may happen that the Windows system cannot start after a power failure. Or sometimes the computer turns on but does not display the screen after a power failure. Windows 10 did not start correctly at startup and stuck in a startup recovery loop. A number of users have reported this issue. After a power failure, the desktop computer refuses to start normally.

Basically, this problem occurs when system files are corrupted due to sudden power failure, Boot Configuration Data (BCD) is corrupted and cannot find the boot path or whatever. So, if you find yourself in a situation where your Windows 10 PC won’t start after a power failure, here are some solutions that might help you fix the problem.

Start Windows 10 in Safe Mode

First of all, check if you can enter Windows in Safe Mode. Basically, this suggests that only the conductors were affected by the sudden power outage. This can be fixed by uninstalling the problematic driver in Safe Mode and then reinstalling it in Normal Mode.

Reinstall Windows

If you suddenly get a blue screen when entering Safe Mode on your computer, the system files may be corrupted. You will need to either repair a reinstall or reinstall the operating system so you need a boot disk if you have one, or you can download Windows 10 from Microsoft. When reinstalling, the registration of your software should be preserved, so your only problem is your personal files. You can connect the hard drive to another computer to recover your files.

Configure automatic restart


Some computers have a BIOS option that prepares the computer for an easier reboot when a lost power is restored. You should check in advance if your computer has this feature and if it is enabled.

Here’s how it’s done:

  • Open the BIOS settings menu of your computer. It is a hardware-dependent process that works the same on all computers, whether you are running Windows or Linux. Restart your computer and make sure the first firmware screen appears.
  • Find the description of the configuration function key. It will be “Setting F2” or F12 or something similar. Restart your computer and press the corresponding function key at the same time. During the initial start-up phase, press the button several times. The BIOS setup menu appears.
  • Find the “Power Settings” menu item in the BIOS and change the “AC Power Recovery” or similar setting to “On”. Find a power-based setting that confirms that the computer will restart when power is present. Some older PCs do not have this feature. If your equipment is present, save the configuration by pressing the function key displayed on the screen. This will restart your computer.

If you are using a UPS to provide short-term battery backup in the event of a power failure, see Additional steps below to connect your equipment. For now, let’s focus on how computers reboot when power is restored.
