What does error 0xc000000f mean and how to fix it?

In Windows 7 and the above assemblies, there are often enough failures when the computer boots, when the error 0xc000000f is displayed on the screen. What is it, to many users is absolutely incomprehensible. Let's look at the nature of this phenomenon, and at the same time we will analyze the methods of correcting this situation.

What does the error 0xc000000f mean when I start Windows?

As already seen, proceeding from the situation itself, it can be noted that the appearance of messages of this type means that the operating system can not be loaded. The reasons for this can be any number. Roughly speaking, the loader does not see the location from which the system information for starting Windows should be loaded, or the download file itself is corrupted.

What is most sad is that if the boot sector is damaged, even checking the disk or restoring the start using specialized utilities does not always help.

Causes of faults

As for the main reasons for the occurrence of system startup failures, the most common ones are: hard disk problems, boot area corruption, system disk errors, incorrect updates, problems with IDE and SATA controller drivers, etc.

System Restore

What you need to do first is to use a boot disk or a USB flash drive. In most cases, the starting error 0xc000000f of Windows 7 or 8 is fixed by the system's rollback (recovery) to the state checkpoint, when such failures have not yet been observed.

You can do this by booting from a disk where the recovery console is selected for work. First you need to use automatic parameters. If the system recovers and error 0xc000000f disappears, you can congratulate yourself with success. But this is only half the battle.

Checking the system drive

So, the system booted. Now it's extremely important to check the system volume (usually it's drive C). Of course, you can use the standard system tool to test the hard drive, which can be accessed through the disk or partition properties menu. In this case, you must use the parameter of automatic error correction.

But only this approach does not always work. The system can at some stage simply output a message that the verification of this volume is impossible. What to do?

In this case, you need to use the command line, in which the command chkdsk c: / f / r is entered. Depending on the hard disk volume and the number of errors, the process can take quite a long time. But it's better to wait. And at the end of the process, to make sure the system is fully operational, the computer will need to be rebooted.

How to Fix a 0xc000000f Error: Restoring the Boot Sector in Windows 7

In some situations, the recovery of the healthiest boot sector of the system can help. If an error occurs when starting 0xc000000f, you must use the boot disk again.

Consider this process for the "seven". First, as is already clear, in the BIOS, you need to set the priority (first) exactly the device from which the download will be made.

After the appearance of the initial Windows installation window, it needs to select the recovery line, after which a list of all available OSes on the computer will be displayed (although it is unlikely that someone has two or more OSs installed simultaneously). Choose Windows 7, and then in a new window - the option "Restore the launch." After a complete check, the system will issue a message with a suggestion to fix the error and restart. We agree and expect that the reboot will show.

It can happen that the error 0xc000000f still remains after that. Here you will need to select the command line in the system restore menu, in which the commands bootrec.exe / FixMbr and bootrec.exe / FixBoot are successively written (after each command the Enter key is pressed.) After that, you will again need to reboot the system.

If this did not work, you will have to enter one more command in the command line. This is bootrec.exe / RebuildBcd. This key is used either to create a new boot partition, or to restore the boot environment (just our case). Again we overload the system and are happy.

Boot Fix in Windows 8

As for the G8, the algorithm is almost the same. Only when you enter the system restore menu, you first have to select the diagnostic menu, and then go to the advanced settings section where automatic recovery is installed.

We are waiting for the end of the process of searching and fixing problems, after which we reboot the computer. It's clear that a 0xc000000f error can pop up again. However, as in the version for the "seven", you will have to use the command line, as described above.

Instead of an afterword

It remains to add that these are just the main methods of correcting errors of this kind, which do not involve the use of third-party utilities. And today they can be found a lot. Among them are worth mentioning such as Hiren's Boot CD, Paragon Hard Disc Manager, FixMBR and many others. But it's better to use, so to speak, a native utility of Microsoft called BCDBoot. But this is in the extreme case, when nothing helps.

As for updates that we did not consider, in part the problem is eliminated by restoring the system or deleting them in manual mode. But, as practice shows, in most cases they are related to this error insofar as. As a rule, the usual rollback of the system almost always gives the desired result. Well, if the winchester is already breathing hard, there's nothing to be done about it - you'll have to change it or, at worst, use something like HDD Regenerator. True, the guarantee of a full recovery of the hard drive, except for the developers themselves (and this is understandable), no one can give.
