Suggested March 2024 Fix Ntldr Is Missing, Press Ctrl

In today’s post, we will identify the causes and then provide the possible solutions to the issue, when you see an error message – NTLDR is missing, Press Ctrl-Alt-Del to restart when you try to boot into the Windows operating system.

The NTLDR file (NT loader) is the boot loader for all releases of the Windows NT operating system and is normally located in the root directory of the active partition on the first boot drive. However, if the NTLDR file is not found or is corrupt, then the loading process halts and the “NTLDR is missing” error screen appears.

NTLDR is launched by the volume boot record of system partition, which is typically written to the disk by the Windows FORMAT or SYS command.

There are few different ways that the “NTLDR is missing” error may present itself, with the first item below being the most common:

Press any key to restart

Press Ctrl Alt Del to restart

Please insert another disk

The most common reason for this error is when your computer is trying to boot from a hard drive or flash drive that is not properly configured to be booted from. In other words, it’s trying to boot from a non-bootable source. This also would apply to media on an optical drive that you’re trying to boot from.

Other possible causes include corrupt and misconfigured files, hard drive and operating system upgrade issues, corrupt hard drive sectors, an outdated BIOS, and damaged or loose IDE cables.

NTLDR is missing, Press Ctrl-Alt-Del to restart

If you’re experiencing this NTLDR error, you can try our recommended solutions listed below in no particular order.

Restart computer

Unplug all removable media

Change BIOS boot order

Reset Active Partition

Update the motherboard’s BIOS

Reseat all internal data and power cables

Rebuild MBR

Reinstall Windows

Replace Hard Drive.

Now let’s delve into the detailed troubleshooting.

1] Restart the computer

Restart your computer. Maybe it was a one-off error and will help. The NTLDR is missing error could be due to the Windows OS not booting properly.

2] Unplug all removable media

Due to the fact that the “NTLDR is missing” issue is often caused by BIOS trying to load from an external non-bootable drive, you can try unplugging all external drives, and remove all removable media, such as CD/DVD, memory cards, and USB devices to make sure the BIOS doesn’t try to load from any of them.

3] Change BIOS boot order

Here, you can check and change the BIOS boot order to ensure that the PC tries to load from an internal drive first.

Here’s how. Make sure that the device you will select has boot files (or Windows operating system files) installed.

Restart the PC.

Press the necessary key to open the BIOS menu. This key depends on the computer manufacturer and computer model.

If the screen shows multiple keys, find the key to open “BIOS,” “setup” or “BIOS menu.”

Use the arrow keys to select the Boot tab.

Move the hard drive to the top of the priority list.

4] Reset Active Partition

If your computer’s partition marked as active does not contain the Windows boot files (or boot files for another operating system), you cannot start your PC and you may receive the NTLDR is missing error.

On Intel-based computers, the system partition must be a primary partition that has been marked as active for startup purposes. There can be only one active system partition at a time. If you want to use another operating system, you must first mark its system partition as active before restarting the computer.

5] Update the motherboard BIOS

You may encounter the NTLDR is missing error if the basic input/output system (BIOS) on your computer is outdated. Make sure that the latest revision for BIOS is installed on the computer. If not, you should contact the computer manufacturer to inquire about how to obtain, and then install the latest BIOS update that is available for the computer.

6] Reseat all internal data and power cables

The error in Windows 10 could be caused by loose or malfunctioning IDE cables. Try replacing the IDE cable with a new one if you suspect it might be faulty.

You’ll need to power down the computer and open the case before reseating any internal data or power cable.

7] Rebuild MBR

If the Master Boot Record (MBR) is corrupted, NTLDR is missing issue may occur. In this case, the only solution is to repair the MBR.

8] Reinstall Windows

Windows reinstallation will almost certainly resolve any NTLDR is missing errors, but it will delete data. So, it is recommended to backup all needed data before reinstalling Windows.

9] Replace Hard Drive

Replacing the HDD should be the last solution you should try. If you still receive the NTLDR is missing error after reinstalling Windows, you’re most likely facing a hardware issue with your hard drive. In this case, you’ll need to maybe replace the damaged hard drive with a new one and then reinstall Windows.

Instagram Music Sticker Missing (How To Fix)

Is the Instagram music sticker missing on Instagram story?

The Instagram music sticker has been out for a while now, and it’s a great way to add mainstream songs to your stories.

In the past, if you want to add music to your videos, you need to use a video editor.

Currently, you can add music to your Instagram story seamlessly by using the music sticker (if it’s available in your country).

However, some users have reported that the music sticker is missing from their stories.

This is a common issue, and many Instagram users have faced it before.

In this article, you’ll learn why your music sticker is gone, and how to fix it on Instagram.

Why is my music sticker gone?

Your music sticker is gone because you recently switched to a business account on Instagram.

Otherwise, the sticker might not be available in your country yet.

Did you recently switch your personal account to a business one?

If you switched your personal account to a business one, you won’t be able to use the music sticker on Instagram.

This is because using the music sticker for a business account is considered as “commercial usage”.

Similar to TikTok, the music on Instagram cannot be used for commercial purposes.

Hence, if your account is a business one, the music sticker will not be available for you.

On the other hand, if you’re living in a country where the sticker is not available, you won’t have access to it as well.

The music sticker is only available to a selected number of countries, so if you don’t have the sticker, it might be because it’s not available in your region.

How to fix missing music sticker on Instagram

To fix the missing music sticker on Instagram, you need to switch to a personal account, delete and reinstall the app, then wait for up to three days.

You can also try connecting to a VPN (a country where the music sticker is available).

The reason why the music sticker is missing is that your account is a business one.

In order to get the music sticker back, you need to switch to a personal account.

Otherwise, you won’t be able to access the music sticker as it cannot be used for commercial purposes.

After you’ve switched to a personal account, it can take up to three days for the music sticker to appear.

In the meantime, you have to either clear the app’s cache or reinstall it.

Here’s a step-by-step guide on how you can do this:

Step #1: Switch to a personal account

Firstly, you need to switch to a personal account.

If your account is a business one, you will not have access to the music sticker as it cannot be used for commercial purposes.

You can also switch to a creator account, but switching to a personal account is much safer.

Here’s how you can switch to a personal account on Instagram:

Once you’ve switched to a personal account, you will regain access to the music sticker.

However, you will lose access to your account’s analytics via “Insights”,

When you switch your account to a personal one, the “Insights” button will no longer exist on your profile.

If you rarely look at your insights, switching to a business account will make no difference to you.

On the other hand, if you always look at your account’s insights, it’s best that you think twice about switching to a personal account.

Before you switch to a personal account, you should weigh the conditions and decide what works best for you.

After all, is it worth it to lose your account’s insights for a music sticker?

Step #2: Delete and reinstall the app

After you’ve switched to a personal account, you need to delete and reinstall the app.

This step is crucial because it tells Instagram that your account is no longer a business one.

Alternatively, you can clear the app’s cache (if you’re using an Android device).

Deleting and reinstalling the app is the best option because it will be automatically updated to the latest version.

In addition, the app’s cache will be cleared once you’ve deleted it.

Here’s how you can delete and reinstall Instagram:

Hold down the Instagram app.

Tap on “delete”.

Install the Instagram app from the App Store/Google Play Store.

If you’re using an Android device, you can clear Instagram’s cache instead.

Here’s how you can clear Instagram’s cache on an Android device:

After you’ve reinstalled Instagram or cleared its cache, force close the app on your background.

For older iPhones, double-tap your home button and swipe up to force close the Instagram app.

For Android devices/iPhone X and above, drag your screen from the bottom to the middle to open the apps’ preview, then swipe up to close it.

Congrats, you’ve successfully deleted and reinstalled the app!

Now, all you’re left with is to wait for the music sticker to appear.

Step #3: Wait for up to 3 days

The final step is to wait for the music sticker to appear on the stickers page.

It can take 24 hours, 48 hours, or up to 3 days for the sticker to appear.

If you’ve deleted and reinstalled Instagram or cleared its cache, you should be able to find the music sticker in your stickers.

If the music sticker is still missing, you have to be patient and wait for a few more days.

Others managed to get it back on the day itself.

If you still haven’t got the sticker after 3 days, you need to report the problem to Instagram in the app.

Here’s how you can report the missing music sticker to Instagram:

Once you’ve reported the problem, Instagram should get back to you soon.

If you’re lucky, they will be able to fix the missing music sticker for your account in one business day.

Otherwise, you may have to wait for up to a week as the Instagram support team is understaffed.

How do I get the music sticker on Instagram?

To get the music sticker on Instagram, tap on your profile picture, add a photo/video, tap on the “Stickers” icon, and tap on the music sticker.

After you’ve tapped on the music sticker, choose a song, edit it, and tap on “Done”.

Finally, tap on “Your story” to add the photo/video with the song to your story.

Why can’t I add music to my Instagram story?

You can’t add music to your Instagram story either because it’s not available in your country yet, or your account is a personal one.

Instagram music is only available in selected countries.

Here are the countries that Instagram music is available in—US, UK, Canada, Germany, New Zealand, Australia, Sweden, and France.

If your country is not in the list, it means that Instagram music is not available to you yet.

In order to bypass this, you need to connect to a VPN.

Firstly, force close the Instagram app on your device.

Next, download a VPN on the App Store/Google Play Store and connect to a country where Instagram music is available in.

After that, open Instagram, tap on your profile picture to add a story and tap on the stickers icon.

You should be able to find and add the music sticker to your story on the second row of the stickers.

If the music sticker is still missing on the Instagram app, it might be because your account is a business one.

In order to have access to the sticker, you need to switch your account to a personal one.


The music sticker is a great way to liven your Instagram stories.

Moreover, it’s a seamless way to add music to your photos/videos.

However, not every country has access to it as Instagram has not resolved the legal issues on their end yet.

Fortunately, you can bypass this by connecting to a VPN where the sticker is available.

In a nutshell, you have to make sure to switch to a personal account instead of a business one.

Otherwise, you won’t have access to the sticker even though it’s available in your country.

If you’ve ever tried booting your PC and were met with an error message stating that the BOOTMGR is Missing. Press Ctrl+Alt+Del to restart then you should know that this is quite a common issue.

The MBR (Master Boot Record) is what controls where the PC boots off of, and is thus essential for a computer’s well-being.

That is why we’ve compiled a list of solutions for you to try that will fix your missing MBR issue, so be sure to read on.

What can I do if my MBR is missing? 1. Restart your PC

Sometimes the fact that your PC can’t detect your MBR may be just the result or a random mishap.

As such, when the error message appears, simply follow the instructions to perform a restart. If this doesn’t work, you should proceed to the next solution.

2. Remove all of your removable media

Because the MBR determines where the PC boots from, removing all removable media will force the PC to boot from its hard drive.

This includes removing all CDs, DVDs and removable flash drive, and connecting them after the boot is finished.

3. Change your Boot order in your BIOS

Boot your PC, and enter the BIOS.

Go to the Boot tab, and change the boot order so that the hard drive containing the MBR is set as the first choice.

Save the changes, and press Exit.

4. Repair your Master Boot Record

Sometimes the missing MBR error can be caused by a severely damaged MBR. If that seems to be the case, then you will need to repair it.

You could try to use a professional third-party tool named MiniTool Partition Wizard, and then follow the above steps.

5. Mark the partition as active 6. Test the hard drive

Follow the steps mentioned above to enter the MiniTool PE Loader interface.

Select the Surface Test feature, and let the program run its course.

Restart the PC.

One common reason for the missing MBR error is the presence of too many bad sectors on that drive.

Expert tip:

7. Perform a Windows Startup repair

Create a bootable USB flash drive or CD/DVD containing your OS.

Use it to enter the Advanced boot options menu.

Go to Troubleshoot, and select Advanced Options.

Choose Startup Repair.

8. Check your cables

Something as simple as old, damaged or improperly plugged cables can also cause the missing MBR error.

As such, turn off your PC, and make sure all cables are plugged, or even try to replace them with new ones (especially the IDE cable).

Sometimes an old BIOS version can also lead to a missing MBR error.  Thus, it is always good to update your BIOS to the latest available version. If you don’t know how to do this, check out our detailed guide.

10. Perform a clean Windows install

If none of the other 9 solutions seemed to work, then your only choice is to perform a clean Windows install.

Keep in mind that this will remove everything from your PC, so it is a good idea to back up all of your data before proceeding with this solution.

Also, if you need to back up your PC professionally, take a closer look at our comprehensive guide of the best backup software for Windows 10.

11. Replace the hard drive

If the missing MBR error seems to be caused by a combination of too many bad sectors, and not even a clean Windows install can fix it, then it is time to retire your hard drive and replace it with a new one.

While this is the most costly solution, it is surely the one that will definitely get rid of any missing MBR errors.

Because the investment is quite serious, you should look for the best hard drive that your budget can afford.

If you’re looking for a good hard drive replacement, you should check out our detailed article for some good suggestions.

How to Fix d3dx9_43.dll Not Found Error

Though the “d3dx9_43.dll missing” error is quite severe, the fixes are overly simple. Try the fixes below in the order they appear. Most of the troubleshooting ideas will also work on legacy Windows PCs like Win 8, 7, Vista, etc.

1. Download d3dx9_43.dll From External Sources

If the error simply occurs as the d3dx9_43.dll file is missing, then this method should fix the issue right away. Here’s what you need to do:

Download the d3dx9_43.dll file.

For 64-bit Windows PC, download the 64-bit DLL file. For 32-bit, download the matching file.

Select the D3DX9_43 and hit Ctrl + C.

Now, go to the following Windows directory:


Hit Ctrl + V to paste the DLL file inside System32.

Now restart the graphics driver and check if the game works or not.

2. Re-Install DirectX

If the above method doesn’t fix the issue, your PC’s DirectX installation is faulty. Follow these steps to fix it:

Pick the language of your choice and hit the Download button.

Follow on-screen prompts to complete the DirectX installation.

Now, restart the PC and test the game app again.

3. Update Windows 11 Display Driver

If you’re using onboard graphics hardware like Intel UHD or a similar kind, do the following to update the display driver:

Hit Windows + I to open the Settings app.

Select Advanced options at the right-side panel.

Apply the display driver-related update from there.

If you don’t find any Optional updates, go to the Device Manager app.

5. Allow Microsoft Store App Updates

Let’s consider that you installed a game app through the Microsoft Store. When trying to play the game, you see the “The file d3dx9_43.dll is missing” warning. In this situation, do the following:

Ensure the App updates feature is active on Microsoft Store.

Go to Settings.

The App updates toggle button should be in the On position.

If it’s ON, you don’t need to do anything. Try other troubleshooting.

Now, activate App updates on Microsoft Store.

Re-install the game app.

6. Apply Pending Windows Updates

Look for Windows updates that you haven’t applied yet. Here’s how it’s done:

Press the Windows + I keys together to open Settings.

Any of the above will help you update the Windows 11 or 10 PC.

Now, reboot the PC and try to run the game app again.

7. Run DISM and SFC on Windows to Fix System Files

Sometimes, corrupted Windows system files can also force a game to malfunction and show the “d3dx9_43.dll not found” error. To fix Windows system files, follow these instructions on your PC:

Choose the Run as administrator hyperlink on the right side.

As the Command Prompt with elevated rights opens, copy and paste this command and hit Enter:

SFC /scannow

The Command Promot will show the system file verification action with a percentage of progress.

If the verification phase of the SFC scan finds any issues, it’ll start repairing those system files.

Once the scanning and repairing task is over, restart the Windows PC.

Now, attempt to launch the game app.

If the SFC scan turns out to be okay and nothing to fix, you need to start the DISM scan. Here’s how:

On the same Command Prompt window, type the following command and hit Enter:

dism.exe /online /cleanup-image /restorehealth

Follow any on-screen instructions and allow the scan to complete.

Once done, check the game app again.

8. Restore the Windows PC

If you know that the game worked before but not working now on your Windows PC, you may want to restore the PC to the last known good configuration. This method rarely works because you may not have created a restore point back then when the game was working. However, it’s worth giving a try by following these steps:

Select the Recovery option under Settings or Best match.

Pick a restore point under the Date and Time column.

Once it’s done and the system reboots, test the game app.

9. Uninstall and Reinstall the Game App

Often, the game app may install with corrupt game files. Hence, the component on the game installation folder that recognizes the d3dx9_43.dll file, may be corrupted. Thus, the game EXE file is unable to determine that the d3dx9_43.dll file is present.

10. Use Dual Boot PC

You can also link the “d3dx9_43.dll not found” error with an incompatible Windows operating system. For example, the game app no longer supports Windows 10 or 11. You need Windows 7 or 8 OSs to run it. In that case, no matter how much you try to replace and fix DirectX DLL files, the game won’t work.

The game app can’t just utilize the DirectX DLL files under the current Windows environment. Thus, you need to resort to dual-boot PCs where you can run Windows 11 along with Windows 7 or 8.
