Fix Boot Device Not Found Error in Windows

If you encounter an error saying, “Boot Device Not Found” when you turn on your Windows 10 computer, then you’ve come to the right place as this post will guide you on how you can fix this problem. Apart from the error message, you will also see a message that states, “Please install an operating system on your hard disk, Hard Disk<xxx>”. You will then be asked to tap the F2 key to initiate the System Diagnostics.

If you install the Windows operating system, it becomes the boot device, and when your computer boots, the UEFI or the BIOS looks for the operating installed on your drive and continues the process. So when you encounter the “Boot Device Not Found” error, this means that the UEFI or the BIOS wasn’t able to locate the drive where it can boot.

There are several suggestions you can check out to resolve this error. You can try checking the connection with your boot drive or change the boot order. You can also fix the Boot Record from Recovery and see if the primary partition is active or not. But before you troubleshoot the problem, make sure that you have a bootable Windows USB drive ready since two of the options provided below will require you to boot into the Advanced Recovery mode. Once you have this covered, proceed to each one of the following options.

Option 1 – Try checking the connection with the boot drive

If you have a custom computer that comes with a cabinet, you might want to open it and remove any connected power supply, and then check the wires. As you know, drives are connected with the motherboard using a cable. So all you have to do is check if both ends are connected properly and make sure that the connection is not loose. You could also try to unplug the cable and plug it back in.

Option 2 – Try changing the boot order

You might also want to try changing the boot order of your computer. Each time a computer boots, the BIOS or the UEFI follows a boot order. It is the one that tells where to first look for the boot drive and if for some reason, a USB is connected to your computer and the first boot device found in the USB, then you have resolved the problem. All you have to do is to remove the USB device and boot or go into the BIOS and change the boot order yourself.

Option 3 – Try to rebuild the BCD files

The next thing you can do to resolve the issue is to Rebuild Boot Configuration Data or BCD files.

  • You can start by booting into the installation environment for Windows 10 from an installation media.
  • After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
  • From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
    • bootrec /FixMbr
    • bootrec /FixBoot
    • bootrec /ScanOS
    • bootrec /RebuildBcd
  • Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed the “Boot Device Not Found” error.

Option 4 – Try setting the System Partition to Active

Like the first given option, you also have to make sure that you have a bootable Windows 10 USB drive before you proceed to set the System Partition to Active. Once you have it covered, refer to these steps:

  • Boot your computer using the bootable Windows 10 USB drive.
  • Next, click Next when you get to the Welcome Screen.
  • Then click on Repair your computer located at the bottom left part of the window and select Troubleshoot > Advanced Options > Command Prompt.
  • After opening Command Prompt, type the following command and hit Enter to start the Diskpart utility. It is a command line-based utility just like Command Prompt but has a UAC prompt once you provoke it. So if you encounter a UAC prompt, just click on Yes to proceed.

diskpart

  • Now type the following command:

list disk

  • From there, select your primary disk by typing the following command:

select disk number

  • After that, list all the partitions on the selected disk by entering the following command:

list partition

  • The command you just entered will list all the partitions created on your PC including both types of partitions that are visible to a normal user in the File Explorer as well as the ones created by Windows 10 by default which helps it in storing the boot files and other important system files.
  • Now type the following command to select the partition that is usually around 100 MB in size:

select partition number

  • Finally, type the following command to mark the partition active:

active

  • Then type the “exit” command to exit the disk part utility.

Once it’s done, the primary drive should now be active and you should now be able to boot into your computer without the “Boot Device Not Found” error.

Disabling the Blur on Login Screen in Windows
You will notice the blurred background on the login screen right away when you start your Windows 10 computer that’s running the v1903 and up. This kind of blurred background is known as “Acrylic Blur Effect on Sign-in Screen”. This new feature delivers a beautiful experience to users by adding more focus to the login screen. However, no matter how nice this feature is and even if it only stays for less than a minute, not all users like it and if you’re one of these users, read on as this post will guide you in disabling the blurred background login screen in your Windows 10 computer. Disabling the blurred background in the login screen can be done in two methods. The first one is via the Registry Editor and the second one is via the Group Policy Editor. Before you proceed, make sure that you are using an admin account and you must create a System Restore point first. Once you have that covered, follow the options provided below.

Option 1 – Disable the Blurred background in the login screen via Registry Editor

  • First, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and hit Enter to open the Registry Editor.
  • After that, navigate to this registry path: KEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem
  • Next, right-click on any empty space in the right pane and create a new DWORD (32 bit) and name it as “DisableAcrylicBackgroundOnLogon”.
  • Once you’ve created the DWORD, double click on it and set its value to 1 to disable it and 0 to enable it.
  • After you make the necessary changes, restart your computer. You won’t now see the blurred background on the login screen.
Note: No matter what option you select to change the background, it will stay blurred when you click on the login button. At the time of writing, there is no way to disable this feature in the Personalization section so the Registry Editor will have to suffice for now.

Option 2 – Disable the Blurred background in the login screen via Group Policy Editor

  • Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
  • After that, navigate to this policy setting: Computer ConfigurationAdministrative TemplatesSystemLogon
  • From there, double click on the “Show clear logon background settings” and since its default value is “Not configured”, set it to “Disabled”. You will see the following description under this setting:
    • “This policy setting disables the acrylic blur effect on the logon background image.”
    • “If you enable this policy, the logon background image shows without blur.”
  • Now click on OK and then check the login screen.
Note: If you don’t configure or if you disable this policy, the logon background image adopts the acrylic blur effect. However, if it didn’t work, you have to restart your computer and then check.

In this article, we will explore many possible reasons why something may occur and offer you straight forward solution on how to escape the situation and prevent it from happening again. Without further delay, let's begin:
  1. Check switch connectors and power outlets

    Yes, sometimes the most basic approach provides the best results, check to see if your power outlet is stable and providing you with constant voltage, if not, maybe you want to invest in a UPS system so you do not face random shutdowns and restarts during work, also while you are at it, check to see if that reset and power switch are connected properly and that they are not dirty or loose.
  2. Clean your PC and check connectors

    Dirt can cause many issues with computers, from overheating to shutdowns to blue screens and memory dumps, check to see if your computer is clean enough and that all connectors are connected tight into their respective sockets.
  3. Check the temperature of your CPU

    CPU overheating can cause so-called random freezes and blue screens, the computer might shut down or restart also without any visible reason. Check to see if your fan on the CPU is working properly and change the thermal paste if needed.
  4. Check the health of your hard drive

    If your hard drive is beginning to go down the path of dying out, many issues can come from this condition. There are many tools on the internet and in Windows itself to check if your hard drive is working properly.
  5. Run antivirus and firewall

    Random lock-ups or similar issues can also occur if by any chance you have some malware on your system, run protection software, and keep it updated to make sure the issue does not come from the computer being infected with malicious applications.
  6. Keep system clean

    Have a habit to clean regularly system files and registries, keep removing unnecessary files from your computer and regularly update your Windows and applications along with drivers.
  7. Run memory test

    Bad RAM bank can cause many issues during the work, check it out to be sure the problem is not RAM itself.
  8. Do not run applications that are too demanding for your system

    Some applications require stronger hardware, and some require the latest hardware, if your computer is a little outdated, running a demanding application can cause issues like freezing, restarts, etc.
  9. Remove applications you do not use

    This does not seem like anything important but if you are not using a specific application just remove it from the system, why? Sometimes an application has some ties to certain services and if it is outdated can cause issues for newer ones.
  10. Stop installing everything you find on the internet

    Yes, that extension for chrome looks cool, yes, that fancy new player seems sick but if it is from an unverified source and from the unknown publisher without any reviews maybe you are better off with it. You can never tell what you might be placing into your system from the internet.
And that's it, 10 reasons and solutions on what to do on random computer freezes, crashes, etc.

How to Fix ACPI.sys Blue Screen Error
If, while using your computer, you encounter the ACPI.sys Blue Screen error, read on as this post will guide you in fixing the problem. The ACPI.sys file is a Windows operating system file that is related to the MSDN 2939. ACPI.sys, the Windows ACPI driver, is an inbox component of the Windows operating system. It is the one that supports the power management as well as the Plug and Play or PnP device enumeration. And so if this file ends up getting corrupted, it is known to cause a Blue Screen error. Another possible cause for the ACPI.sys Blue Screen error includes RAM issues, incompatible firmware, hard disk issues, corrupted drivers or malware infection, and so on. Here are some Blue Screen errors that can be triggered by the ACPI.sys file:
  • KMODE EXCEPTION NOT HANDLED
  • PAGE FAULT IN A NONPAGED AREA
  • SYSTEM THREAD EXCEPTION NOT HANDLED
  • IRQL NOT LESS OR EQUAL
  • KERNEL DATA INPAGE
  • SYSTEM SERVICE EXCEPTION
To fix the Blue Screen error associated with the ACPI.sys file, refer to the instructions provided below.

Option 1 – Try to recreate the ACPI.sys file

If the first option didn’t work, the next thing you can do is to recreate the ACPI.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. This is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.
  • Boot your Windows 10 PC in Safe Mode.
  • Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
  • From there, look for the file named ACPI.sys and rename it to ACPI.old.
Note: As you can see, the file’s extension has changed from .sys to .old.
  • Now restart your computer and check if the ACPI.sys Blue Screen error is now fixed.

Option 2 – Try to update or rollback the ACPI Driver

The first thing you can try to fix the Storport.sys Blue Screen error is to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.
  • Tap the Win + X keys to open the Win X menu and from there, select the Device Manager.
  • After opening the Device Manager, look for the ACPI.sys driver and right-click on it, and then select Properties.
  • Next, go to the Driver section. Note that the rollback option would only be available if you’ve recently updated the ACPI.sys driver. So if you can’t see it then click on the Update Driver button.
  • After that, Windows will automatically check for the problems that could be related to the Blue Screen error.
  • Finally, restart your computer. It will just reinstall the device drivers automatically.
Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver. On the other hand, if updating the ACPI driver, didn’t work, you can also try to copy the ACPI.sys system driver file from the System32 folder of another computer that’s functioning properly and runs the same Windows OS version. Afterward, place it on your problematic computer and check if it fixes the BSOD error or not.

Option 3 – Run System File Checker or SFC scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.
  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
 Reboot your PC.

Option 4 – Run the Blue Screen Troubleshooter

Troubleshooting Blue Screen of Death errors wouldn’t be complete without the Blue Screen troubleshooter. As you know, it is a built-in tool in Windows 10 that helps users in fixing BSOD errors like ACPI.sys. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:
  • Tap the Win + I keys to open the Settings panel.
  • Then go to Update & Security > Troubleshoot.
  • From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 5 – Run System Restore

  • Tap the Win + R keys to open the Run dialog box.
  • After that, type in “sysdm.cpl” in the field and tap Enter.
  • Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
  • After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Fix Windows Activation Error 0xC004F212
Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:
“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”
Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:
  • Go to Settings and then select Activation.
  • After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.
The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.
  • Extract the Windows 10 ISO files using an extractor.
  • Then browse to the folder you created and go to the sources folder.
  • From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:
[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
Note: “xxxxx” is the KEY to your Windows version.
  • Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.
Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.
