How to fix inaccessible boot device BSOD in Windows 10

The inaccessible boot device error is one of the most frustrating errors Windows users can experience. When this error appears, it means that Windows 10 was unable to access the system files it needs to boot up properly.

Why does this error occur?

This error can have a variety of causes, but it typically indicates that the computer’s BIOS is unable to access the boot disk. There are a few common causes of this error, including incorrect BIOS settings, a corrupt boot disk, or a damaged hard drive. In most cases, it is relatively easy to fix the INACCESSIBLE BOOT DEVICE BSOD by simply changing the BIOS settings or replacing the boot disk. However, if the problem is caused by a damaged hard drive, it may be necessary to replace the drive entirely. In any case, it is always important to make sure that all of your important data is backed up before attempting to fix this error.

What to do when you see the inaccessible boot device error?

There are a few different things that can cause this problem, so it’s important to troubleshoot the issue to determine the best course of action. One possible cause is a corrupted or outdated BIOS. In this case, you’ll need to update your BIOS to resolve the issue. Another possibility is a hardware issue, such as a faulty hard drive or motherboard. If this is the case, you’ll need to replace the defective component to get your computer up and running again. In either case, it’s important to consult with a professional before taking any further action.

Undo any hardware changes

This error is usually caused by hardware changes, such as adding or removing RAM, replacing the power supply, or installing a new hard drive. If you experience this error, it’s important to undo any hardware changes that you’ve made before rebooting your computer. Otherwise, you may see the BSOD again or experience other errors. In some cases, you may need to perform a clean install of Windows to resolve the BSOD issue. However, this should only be done as a last resort.

Reset the BIOS to factor if needed

BSOD can be caused by hardware or software issues, and it can be difficult to pinpoint the exact cause of the problem. If you have made any changes to your BIOS, such as overclocking your processor or changing your boot order, you may need to undo these changes to fix the BSOD issue. To do this, you will need to enter the BIOS setup utility and navigate to the relevant menus. Once you have made the necessary changes, save and exit the BIOS, and your system should boot normally.

Toggle AHCI Mode in BIOS

To fix this, you will need to change the Toggle AHCI Mode value to Enabled. Here’s how:

1. Restart your computer and enter BIOS setup. Consult your motherboard manual if you are unsure how to do this.

2. Once in BIOS setup, navigate to the SATA Configuration section. Again, consult your motherboard manual if you are unsure where this is.

3. Within the SATA Configuration section, there should be a setting called Toggle AHCI Mode. Set this to Enabled and save your changes.

4. Exit BIOS setup and boot into Windows. You should no longer see BSOD errors.

Check if your hard drive is failing

Hard drive failure can be a devastating event, leading to the loss of important files and hours of frustration. However, several warning signs can indicate that a hard drive is about to fail. If you notice any of these signs, it’s important to back up your data and replace the hard drive as soon as possible. One common sign of hard drive failure is Frequent disk errors. If your computer is displaying frequent disk errors, it’s a good indication that the hard drive is about to fail. Another sign to watch out for is Slow performance. If your computer’s performance has slowed down significantly, it could be due to a failing hard drive. Finally, if you notice strange noises coming from the computer, such as clicking or grinding, this is another sign that the hard drive is failing and needs to be replaced. By being aware of these signs, you can take steps to protect your data and avoid the frustrations of hard drive failure.
