Windows Setup in Continuous Reboot Loop – What is it?

After upgrading to Windows 10 operating system from Windows 7 or Windows 8/8.1, a lot of Windows users are complaining about the Windows setup in a continuous reboot loop. The computer would just keep on rebooting every time the machine is booted and this incites frustration for a lot of Windows users.

Solution

Error Causes

When Windows launched the third update for Windows 10, users trying to upgrade to Windows 10 encountered an endless reboot loop problem. The computer will crash repeatedly. The KB3081424, which is a roll-up of bug fixes of Windows 10, continuously fails once you start the update process and then triggers a message showing: “We couldn’t complete the updates, undoing the changes.” The undoing process will then cause a system reboot mandatorily.

Once you log back on your computer again, the Windows 10 update will try to reinstall KB3081424. You will not be able to stop the update which will cause your Windows setup in a continuous reboot loop.

The KB3081424 will not be successfully installed since if it fails for the first time, that initial failure can be detected to create a bad entry in your Windows 10 registry. This will then prevent your subsequent attempts to reinstall KB3081424 to make it work correctly.

Further Information and Manual Repair

In order to fix the problem of Windows 10 setup in a continuous reboot loop, there are a few methods you can try. Try following these simple steps and you’ll be able to get rid of the problem.

Note: If you’re not highly confident to solve this issue on your own, it is highly recommended to consult an authorized computer technician who would be knowledgeable enough to fix the issue for you. In addition, you can also use a system optimizer to resolve the issue.

Method One: Check For Windows Update

Microsoft Windows released an updated fix for the Windows setup in continuous reboot loop problem. You can try fixing the issue through Windows Update.

1. Open Settings
2. Go to Update & Security
3. Select Windows Update then choose Check for updates

At this point, an additional update will be installed and downloaded to your operating system to resolve the continuous reboot loop problem.

Method Two: Eliminate Bad Registry Entry

Before KB3081424 attempts to install again, you can try doing this solution:

1. Click on the Start menu then type regedit
2. Once the window opens, go to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionProfileList
3. Create a backup for your registry key (since this process is a bit risky). Select ProfileList then click on File and Export then choose your backup name.
4. From the ProfileList IDs, remove anything with ProfileImagePath in it.
5. Close Regedit then reboot. By this time, the KB3081424 should properly install.

Method Three: Perform A Startup Repair

Another thing you can try to solve the Windows setup in continuous reboot loop problem is to perform a startup repair from a working computer.

1. Ensure that all unnecessary devices are disconnected from your computer as your computer might detect them.
2. If you are connected to a network, you need to disconnect from this as well.
3. On a working computer, download the Windows 10 ISO then you can perform a startup repair.
4. Boot your computer from the Windows 10 DVD.

To change your BIOS option to boot from the Windows 10 DVD, follow these steps:

1. Boot your computer then press the F2 function key to enter setup.

NOTE: You must do this quickly since the BIOS loads rapidly.

2. Once you’re inside the BIOS, navigate to the Boot Configuration screen. On this screen, you’ll be able to change the first device to be loaded.
3. Go to Removable Devices then hit Enter. Removable devices could either be a thumb drive or DVD. Select DVD to put it at the top and be the first boot device.
4. Save your changes by pressing on the F10 function key. A setup confirmation box will appear with a message Save configuration changes and exit now. Select Yes.
5. Exit BIOS by pressing on the ESC key. You should be prompted to boot from the Windows 10 DVD at this point.

If you're not able to execute the aforementioned processes on your own, get help or download and install a powerful system optimizer to assist with the windows continuous reboot loop process and other Windows 10 error messages.

If your Microsoft Edge browser encountered a Stop Error that says, “INVALID_POINTER_READ_c0000005 (atidxx64.dll)” in your Windows 10 computer, then this indicates that your Graphics card driver is outdated. According to security experts, Microsoft has already acknowledged the problem and stated that this issue exists with Windows 10 v1809, Windows Server 2019, and Windows Server version 1809. Although there is no direct way to resolve the problem, there are still some workarounds you can try. If you are using a RadeonHD2000 or HD4000 series video card, the update will be blocked for you. Some users also claim to experience performance issues with the lock screen or the ShellExperienceHost. However, if you are using AMD, the problem is that it no longer supports Radeon HD2000 and HD4000 series graphics processing units or GPUs. Even though Microsoft is already working for a way to resolve the problem, here are some alternative solutions you can check out:

Option 1 – Update your Graphics card drivers

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 2 – Try removing AMD Radeon HD2000 and HD4000 drivers

Although this is not exactly a perfect solution, removing AMD drivers will make the operating system fall back to the default GPU available on your motherboard. You also have the option to completely disable the hardware.

• Tap the Win + X + M keys to open the Device Manager.
• Next, look for your Graphics card drive, and under Display Adapters, right click on them and click Uninstall device or Disable device.
• After that, restart your computer. This will disable the AMD drivers so you won’t be able to find them. It will also release the Windows 10 v1809 update on your computer and in case your operating system tries to prompt you with the “New Device found” message, simply ignore it.

Option 3 – Try to use another browser

You might want to use another browser especially when you already updated your computer and Microsoft Edge still keeps on crashing. You can use Google Chrome, Mozilla Firefox, and other browsers as alternatives until you sort out the problem.

Option 4 – Try to remove the Graphics card physically

You might also want to try removing both AMD Radeon HD2000 and HD4000 as they are very old graphics cards. And since AMD is not going to roll out anything, at least on its own if your motherboard has an onboard GPU, it would be best to get rid of the cards. After that, install the Windows v1809 update and then put them back in. You also have the option to install the driver but just don’t use Microsoft Edge.

If you are trying to run Windows Upgrade on your Windows 10 computer but suddenly interrupted by the error 0x800F081E – 0x20003, worry not for this post will guide you on how you can fix this Windows Upgrade error. This particular Windows Upgrade error is a Windows status code for CBS_E_NOT_APPLICABLE which indicates that some of the update requirements are missing or the files that are installed are already of a higher version compared to the ones that are still pending. In most cases, this error occurs when you try to upgrade to earlier versions of the Windows 10 N edition to a later version. Here’s the full content of the error message:

“0x800f081E-0x20003, The installation failed in the SECOND_BOOT phase with an error during BOOT operation”

In case you don’t know, Microsoft distributes special “N” editions of Windows in Europe and the “KN” editions in Korea. These editions are the same as the standard editions of Windows except that they do not have the Windows Media Player as well as the multimedia playback features. Thus, when the Windows Upgrade fails with the error code and error message and it doesn’t provide much information as to why the update couldn’t be installed, there is something you can do about it to fix the error. Since Windows uses generic error codes and so if you see the error code 0x800f081e, you have to check the error log first. For more details, follow the instructions laid out below. Step_1: You need to navigate to C:$WINDOWS.~BTSourcesPanther and from there look for the text file named “setuperr.log” and open it with a text viewer/editor program like Notepad. Step_2: After opening the setuperr.log file, you should see content that’s similar to this:

C:WINDOWSSoftwareDistributionDownload80b2677d6e15a2a206625bb25a7124feamd64_Microsoft-Windows-MediaPlayer-Package~~AMD64~~10.0.17134.1. Error: 0x800F081E 2019-09-10 20:26:57, Error SP Operation failed: Add [1] package C:WINDOWSSoftwareDistributionDownload80b2677d6e15a2a206625bb25a7124feamd64_Microsoft-Windows-MediaPlayer-Package~~AMD64~~10.0.17134.1. Error: 0x800F081E[gle=0x000000b7]

Note: From the content above, it is clear that the Windows Upgrade failed due to complete due to the Windows Media Player. It could be that the log file may contain other error messages and other error codes and if you see the error code 0x800f081e from the list, then you need to uninstall the Media Feature Pack. Step_3: You have to uninstall the Media Feature Pack.

• Tap the Win + R keys to launch the Run dialog box and type “optionalfeatures.exe” in the field and hit Enter to open the Windows Features wizard.
• Next, you need to wait until the list of Windows Features populates and then click on the + sign to collapse the folder of the Media Features.
• After that, uncheck the “Windows Media Player” option from the Media Features folder.
• Now click on the Yes and OK buttons to save the changes made and then close the Windows Features dialog box.
• Restart your computer and boot, try to run the Windows Upgrade process again, and check if the error is fixed or not.

Note: If the installation has been successfully completed, you have to go back to the Windows Features and enable the Windows Media Player again. And if you are using the Windows 10 N Edition, then you can just download and install the latest version of the Media Feature Pack for your Windows 10 N edition. On the other hand, running the built-in Windows Update troubleshooter could also help you resolve any Windows Update-related problems, including the error 0x800F081E – 0x20003. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button.

If you are trying to install a Feature Update in Windows 10 but you got the error code 0x80190001, then it means that there is something wrong with the installation files. The installation files are either corrupted or some of them failed to be downloaded. On the other hand, the issue might also have something to do with a driver issue. When you encounter error 0x80190001, you will see the either of following error message on your screen:

“Something went wrong Couldn’t download Windows 10, please check your network settings and try again. You can contact Microsoft support for help with this error. Here’s the error code 0x80190001”. Or: “An unexpected error was encountered while attempting to download files required for the upgrade”.

Here are some fixes that could help you resolve the error 0x80190001. Follow them carefully.

Option 1 – Run the Network Troubleshooter

As mentioned in the error message the issue might have something to do with the network settings of your computer so you can try to run the Network Troubleshooter and then try updating or installing Windows 10 again.

Option 2 – Update Network drivers

• Tap the Win + R keys to launch Run.
• Type in msc into the box and tap Enter or click OK to open the Device Manager.
• After that, look for Network Adapters from the list of device drivers displayed. Once you find it, expand it to see the Network drivers.
• Right-click on it and select the option “Uninstall device” – do the same thing for the other Network drivers.
• Restart your PC so Windows can detect and reinstall the drivers you just uninstalled.

Option 3 – Use Storage Sense to clean up temporary and junk files

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space.
• Now make sure that the Storage Sense feature is turned On then go find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
• Windows Upgrade Log Files
• The system created Windows Error Reporting Files
• Thumbnails
• Temporary Internet Files
• Previous Windows Installation Files
• Delivery Optimisation Files
• DirectX Shader Cache

Note: Once you’re done freeing up space on your drive, try to run the setup file again.

Option 4 – Delete the contents in the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. A lot of users tried deleting the files in this folder to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits

• After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

 Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

Option 5 – Run the Windows Update Troubleshooter

You might also want to run the Windows Update Troubleshooter as it is also known to help users resolve Windows Update errors like error 0x80190001.

Option 6 – Try to disable your antivirus program

Disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 7 – Try to use the Media Creation tool

The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.

• After making the bootable drive, you need to plug it into your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

In case you don’t know, the Windows Registry contains a System Hive which is a core part of Windows. The Windows operating system store various settings, options, and configurations. And if you encounter a Device Manager Error 49 for a device then it means that the system hive has exceeded its size limit. Worry not for this post will provide you with possible solutions that can help you in fixing error code 49. You will see the following error message when you encounter error code 49:

“Windows cannot start new hardware devices because the system hive is too large (exceeds the Registry Size Limit), (Code 49)”

There are instances when it may so happen that the device or devices are no longer attached to the computer but they are still listed in the system hive of the registry. For instance, if you were removing hardware and application for years but they weren’t removed from the registry then the size of the system hive keeps on growing until it hits the maximum limit. As you know, making changes in the registry manually, no matter how knowledgeable you are on such things is not sage since the registry is not only important but also complex. In addition, the System Hive is also a permanent part of the Registry associated with a set of files that contain information related to the configuration of the computer on which the OS is installed. To resolve this error, you must remove or uninstall any hardware devices that are no longer in the system. In fact, the Device Manager hides them by default so you need to enable hidden or non-present devices. Follow the instructions given below to set the Devices Manager to display devices that are no longer connected to the computer. Step 1: Tap the Win + R keys to open the Run dialog box. Step 2: After that type in “cmd” and hit Enter to open the Command Prompt. Step 3: Type “set devmgr_show_nonpresent_devices=1” in the Command Prompt and hit Enter to enable the hidden devices option. Step 4: After that, exit Command Prompt and tap Win + X + M to open the Devices Manager. Step 5: After opening the Devices Manager, click on View and then select the “Show hidden devices” option. This will show you all the devices that are not connected to the computer but are still mentioned. Step 6: Next, select a non-present device and click Uninstall from the Driver tab. Step 7: After that, repeat what you’ve done on step 5 for any other device that you no longer use. Step 8: Restart your computer. You can check the device Properties dialog box in the Device Manager after you’re done removing all the useless devices, to check if the error is now fixed or not. Moreover, you can also try running the Hardware and Devices Troubleshooter as it can also help resolve hardware-related problems. To use it, refer to the steps below.

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

On the other hand, you can use the options below if you encounter Error Code 0x80090016 while setting up your PIN.

Option 5 – Try to manage the NGC Folder

• You need to boot your computer into Safe Mode first.
• Next, delete all the contents of the NGC folder and you can do that by taking ownership of the folder first. To do so, refer to these sub-steps:
  • First, locate the concerned folder and right-click on it then select Properties.
  • Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
  • After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
  • Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
  • Now edit the permission to Full Control for “Everyone”.
  • Click OK to save the changes made and then exit.
• After you take ownership of the folder, you can now delete all of its contents.
• Once you’re done, restart your computer and see if the problem is fixed.

Option 6 – Try to use the Group Policy Editor

• Tap the Win + R keys to open the Run dialog box
• Then type “gpedit.msc” in the field and hit Enter or click OK to open the Group Policy Editor.
• Next, navigate to this setting: Computer Configuration > Administrative Templates > System > Logon
• After that, double click on “Turn on convenience PIN Sign-in” and set its radio button to Enable. This policy setting has the following description:

“This policy setting allows you to control whether a domain user can sign in using a convenience PIN. If you enable this policy setting, a domain user can set up and sign in with a convenience PIN. If you disable or don’t configure this policy setting, a domain user can’t set up and use a convenience PIN. Note: The user’s domain password will be cached in the system vault when using this feature. To configure Windows Hello for Business, use the Administrative Template policies under Windows Hello for Business.”

• After you set the radio button to Enable, it will turn on the Logins using the PIN. Note that setting the radio button to Disabled or Not Configured will turn off the Logins using the PIN.
• Now exit the Group Policy Editor and restart your PC so that the changes can take effect.
