Windows does not start

What to do when Windows doesn't start:

If you're trying to start your computer and Windows refuses to boot, what should you do? "Windows doesn't start" is a common issue with various possible causes. Here are some troubleshooting steps:

First steps: Has anything changed?

Think about any modifications you've made recently to your computer. Have you connected any new hardware, updated any new device drivers, or opened the computer case and made any adjustments? A problematic driver, unsuitable hardware, or an unintentional disconnect from something within your computer could all be the culprits.

Here are some specific examples of what you might have done:

  • You installed a new driver for your printer, but the driver was not compatible with your printer model.
  • You connected a new USB device to your computer, but the device was not properly supported by your operating system.
  • You opened the computer case and accidentally disconnected a cable.

If the computer doesn't start at all:

If your computer doesn't start at all, make sure it's connected to a power source and the power connector is secure. For a desktop computer, check that the power switch at the back - the power supply - is set to "On." If it still doesn't start, it's possible that you accidentally disconnected the power cable inside the computer. If you haven't disconnected anything inside the computer, the power supply may be faulty, and in that case, it needs to be replaced.

Also, remember to check your computer monitor - if your computer seems to be booting up, but the screen remains black, ensure that the monitor is powered on and the cable connecting it to the computer case is securely attached at both ends.

Computer starts but displays "No bootable device":

If your computer starts but displays a black screen with a message like "No bootable device" or another "disk error" message, it means your computer is unable to boot from the hard drive where Windows is installed. Access your computer's BIOS or UEFI firmware settings and check the boot order setting to ensure the Windows boot sequence is configured correctly.

When your computer starts up, it tries to boot the operating system from the devices listed in the boot order. If the boot order is incorrect or if the bootable device is faulty, you may receive an error message stating "No bootable device." To fix this, you need to check your computer's BIOS or UEFI settings.

Start your computer and look for the key or key combination that opens the BIOS or UEFI settings. Typically, this key is Delete, F2, F10, or Esc. If you're unsure, consult the computer manufacturer's website or user manual.

Once you're in the BIOS or UEFI settings, locate the "Boot" section. Here, you should see a list of boot devices and their order.

  1. Ensure that the hard drive where Windows is installed is set as the primary boot device. You can change the boot order using the arrow keys or function keys indicated at the bottom of the screen. Move the hard drive above the boot order list so that it boots first.
  2. Save the changes you made in the BIOS or UEFI settings and restart your computer. Now your computer should attempt to boot Windows from your hard drive.

If these steps don't resolve the issue, you may need to check the hard drive or reinstall Windows. Windows boot problems can be frustrating and challenging to troubleshoot. These were a few different reasons why your computer may not start, and we provided some tips on how to resolve the issue. We understand the frustration and difficulties caused by Windows boot problems, and we're here to help. Always remember to check all cables and devices before attempting any other solutions. If the problem persists, don't hesitate to seek further assistance!

If the previous steps didn't solve the issue, here are a few additional suggestions:

Safe Mode: Try booting your computer in Safe Mode. This mode starts Windows with only the necessary drivers and services, which can help identify and resolve software conflicts or issues. To access Safe Mode, restart your computer and repeatedly press the F8 key (or another key specified by your computer manufacturer) before the Windows logo appears. From the Advanced Boot Options menu, select Safe Mode.

System Restore: If you recently installed new software or made changes to your computer settings, a System Restore can revert your system back to a previous working state. To perform a System Restore, boot your computer in Safe Mode and access the System Restore tool through the Control Panel or by searching for "System Restore" in the Start menu.

Startup Repair: Use the Startup Repair tool to automatically fix certain startup issues. You can access this tool by booting your computer from a Windows installation disc or USB drive. Follow the on-screen prompts to initiate Startup Repair.

Check for hardware issues: If software-related solutions haven't resolved the problem, it's worth checking for hardware issues. Ensure all hardware components are properly connected and seated in their slots. If you recently added new hardware, try removing it to see if the computer starts normally.
