In the Windows 7 operating systems and assemblies above, quite often there are crashes when the computer starts , when the error 0xc000000f is displayed on the screen . What is it, many users absolutely incomprehensible. Let us look at the nature of this phenomenon, and at the same time analyze methods for correcting such a situation.
What does error 0xc000000f mean when starting Windows?
As already seen, based on the situation itself, it can be noted that the appearance of messages of this type means the inability to load the operating system. The reasons for this may be any number. Roughly speaking, the bootloader does not see the location from which the system information for starting Windows should be loaded, or the boot file itself is damaged.
The saddest thing is that if the boot sector is damaged, even checking the disk or restoring the startup using specialized utilities does not always help.
Causes of Failures
As for the main prerequisites for the appearance of failures during system boot, the most common ones are the following: problems with the hard disk, damage to the boot area, errors on the system disk, incorrect installation of updates, problems with the drivers of IDE and SATA controllers, etc.
System Restore
What you need to do first thing is to use a boot disk or USB flash drive. In most cases, the start error 0xc000000f of Windows 7 or 8 is corrected precisely by rolling back (restoring) the system to a state checkpoint when such failures have not yet been observed.
You can do this by booting from the disk, where the recovery console is selected for operation. First you need to use automatic parameters. If the system recovers and error 0xc000000f disappears, you can congratulate yourself on the success. But this is only half the battle.
Checking the system drive
So, the system booted up. Now it is imperative to check the system volume (usually a C drive). Of course, you can use the standard system tool to check the hard drive, which can be accessed through the disk or partition properties menu. In this case, you must use the automatic error correction option .
But only such an approach does not always work. The system may at some stage simply display a message stating that verification of this volume is not possible. What to do?
In this case, you must use the command line, in which the command chkdsk c: / f / r is entered. Depending on the size of the hard disk and the number of errors, the process can take a rather long period of time. But better to wait. And at the end of the process, to make sure that the system is fully operational, the computer will need to be rebooted.
How to fix error 0xc000000f: restore boot sector in Windows 7
In some situations, restoring the boot sector of the system itself can help. If an error occurs when starting 0xc000000f, you must again use the boot disk.
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 boot will be performed.
After the initial window for installing Windows appears in it, you need to select the recovery line, after which a list of all the OS available on the computer will be displayed (although it is unlikely that someone will have two or more OS installed at the same time). We select Windows 7, and then in the new window - the option "Restore Startup". After a full check, the system will display a message asking you to fix the error and restart. We agree and wait for the reboot to show.
It may happen that after that the error 0xc000000f will still remain. Here you will need to select the command line in the system recovery menu, in which the bootrec.exe / FixMbr and bootrec.exe / FixBoot commands are sequentially written (after each command the enter key (Enter) is pressed. After that, a system reboot will be required again.
If this does not help, you will have to enter another command at the command prompt. 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). We overload the system again and rejoice.
Windows 8 boot fix
As for the G8, the algorithm here is almost the same. Only when entering the system recovery menu, you first need to select the diagnostics menu, and then go to the advanced settings section, where automatic recovery is installed.
We are waiting for the end of the troubleshooting process, and then we restart the computer. It is understood that error 0xc000000f may 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 for fixing errors of this kind, which do not imply the use of third-party utilities. And today you can find a lot of them. Among them, it is worth noting such as Hiren's Boot CD, Paragon Hard Disc Manager, FixMBR and many others. But it is better to use, so to speak, the native Microsoft utility called BCDBoot. But this is in extreme cases, when nothing helps.
As for updates that we did not consider, the problem is partially fixed by restoring the system or deleting them manually. But, as practice shows, in most cases they are related to this error insofar as. Typically, a normal system rollback almost always gives the desired result. Well, if the hard drive is already breathing, there is nothing to be done - you will have to change it or, at worst, use something like HDD Regenerator. True, no one can give guarantees for the full restoration of the hard drive, except for the developers themselves (and this is understandable).
