Today we’ll look at an interesting error 0xc00000e9, which occurs when installing Windows, and the version can be any - from seven to ten. Although in the latter, the developers try to stop such errors as much as possible.

Reasons for the appearance of 0xc00000e9

So, we see a black background and error 0xc00000e9 in the \Boot\BCD file. We already had problems with this file, I described it in the article about the problem with error 0xc0000034. To solve this system malfunction, you can take different paths where there is a solution. But first, let’s figure out why the error could occur in the first place:

• The integrity of system files has been compromised.
• Damage to the hard drive.
• The appearance of BAD blocks on the hard drive.
• Problems with the device from which you are installing Windows (for example, a flash drive).
• There is a violation in the downloaded assembly, it is better to take original system images.
• Damage to a layer in the boot CD.
• Viruses.

And there are many, many different reasons that can become a problem. Of course, only you know why this error appears, maybe you did some manipulations in the system, installed software, changed BIOS settings.

Let's try to figure out how to completely get rid of the black screen with letters and numbers that prevent us from booting into Windows.

If the error occurs when installed system, then the problem may be with updates or damage to the hard drive. To check, we need , which will show us bad blocks, the so-called bad sectors. There are versions that can be written to a flash drive and used there. You can download it from here. Bad sectors will be shown in red; if there are a lot of them, then the problem is clearly in the disk.

It should be remembered that an outdated hard drive that is 7 years old will not last long. It is better to replace it immediately, otherwise at some point you will have to say goodbye to all your files and system.

Also, if the hard drive is suspect, I want you to try connecting it to a different SATA port. If your motherboard is also old, then one of the ports may have failed. Although this happens extremely rarely.

Extract everything external devices connected to your PC: flash drives, external HDDs, smartphones, etc.

Perhaps the problem is with the updates.If you suspect Windows updates If error 0xc00000e9 appears, you should roll back to the restore point.

Other solutions to 0xc00000e9

In short, there are several more methods that have little relevance to the matter, but the likelihood of correcting the error will increase if we do something there.

First, you need to download some kind of registry cleaning utility. The best one is probably CCleaner. You are downloading the Portable version, and not the one that needs to be installed. You put it on a flash drive. Now boot through (if possible) and try cleaning the registry using this utility.

Why is this method ineffective? When using safe mode, components that are vital for booting the system are loaded: without unnecessary drivers and programs. I can’t say how much this affects the registry.

• In safe mode, or via a flash drive to restore them command line execute command sfc /scannow.
• Try it.
• Effective method– system reinstallation.

What if even reinstallation didn’t help? Then there is a possibility of physical damage to components - SATA ports, hard drive, motherboard. This especially affects older computers. Here you will have to figure it out yourself, and if you don’t know how, then contact the service center.

These are the methods we looked at to fix 0xc00000e9. Unfortunately, it is very sad that the appearance of such errors does not indicate a specific reason, but you can deal with the problem on an intuitive level, especially if you are a more or less experienced specialist. By the way, error 0xc00000e9 when loading Windows 7 can be easily fixed using the methods described above. I hope everything works out for you!

It happens that out of the blue the monitor screen turns black and signals an error. Moreover, this same problem with code 0xc00000e9 when loading Windows 7 occurs again and again. We can deal with it, but first we’ll find out why it appeared.

Causes

The reason for the occurrence when loading Windows 7 may be:

• Registry problems. A downloaded and installed program (especially from an unreliable source) can damage important operating system data with its registry files.
• Files needed by the system were deleted by the virus program.
• Problems during installation or after. If during Windows installations Some error occurred, or the assembly was not entirely successful (this applies to an unsuccessful pirated version), then there may be some problems like this.

We fix it

Because this problem occurs during the startup of the operating system, you can load Windows as usual and it will not be possible to fix it. Therefore, you can get into the OS and eliminate 0xc00000e9 when loading Windows 7 using other methods.

Reboot the computer, then press F8 until the operating system loads. Instead, additional boot options will appear, from which you need to select “Last Known Good Configuration”.

After which the computer should boot from the moment of the last successful startup. Now you can scan the registry using special utility, for example WinThruster. This is one of best utilities to detect problems in the registry, but, unfortunately, with a paid license. You can also delve into the registry manually, but it’s better not to go there without special knowledge, otherwise you can make the situation worse.

In addition, it would not be a bad idea to completely scan your computer with an antivirus for a virus that may be to blame for all the troubles.

Rollback

Probably the simplest and most effective way to fix it when booting Windows 7 on a laptop is to do a system restore. This process is capable of using a previously saved restore point. Usually it is created immediately before installation different programs, during computer startup, and at other times that can be configured.

You can view available restore points and make a rollback like this. We also start from the last known good configuration. If it fails, then go to (the same additional boot options, F8 key). We run to Start // All // Accessories // System Tools and launch “System Restore”. We go through “Next”, where the available points with the date and reason for creation will be indicated in the window.

We select the one that was created before it appeared when Windows 7 loaded, and then return to it. At the same time, everything installed programs after its creation will be deleted. You can see exactly what you will have to sacrifice by clicking on the appropriate button.

If you couldn’t do this via F8 due to problem 0xc00000e9 when loading Windows 7, you can roll back the laptop using boot disk or flash drives. The system on the media must be exactly the same as the one installed on the computer. When the Windows 7 installation window opens, instead of “Install,” click on “System Restore” at the bottom left. Then everything is the same.

Reinstallation

If everything is hopeless and the problem 0xc00000e9 disappears, you should reinstall the OS. If there licensed disk or at least a normal working assembly, then we just install it as before, and that’s it.

If, after reinstallation, error 0xc00000e9 does not disappear when loading Windows 7 on the laptop, then the problem is in the internal hardware. In this case, you must contact service center to diagnose and replace damaged components. However, this procedure will take a lot of time and money.

be careful

You should always be careful when downloading different software from unknown sites. If you don’t like the resource right away, it’s better to leave it, otherwise you might end up with not only a problematic program, but also a virus or two. The same applies to downloading a pirated OS. It’s better not to do this at all, but if you really have to, you need to choose carefully, otherwise you may be left with nothing.
