Error 0xc000000f can visit you quite suddenly - when you start your Windows OS. Just at that moment when you least expect it. There are no particularly noticeable symptoms that portend the appearance of this problem. Simply, one day, your computer, at the next system startup, will show you the following information:
Failed to start Windows. This may have happened due to a recent hardware or software configuration change. To resolve the error:
Insert boot Windows disk and restart your computer.
Select your language options, and then click Next.
Select "Repair your computer".If this disc is missing, please contact system administrator or computer manufacturer.
Status: 0xc000000f
Details: The boot menu failed because the required device is not available.
Reasons for the error
You don't have to go far for a list of reasons, as much is already clear in the error message. Errors such as 0xc000000f appear mainly due to the fact that something happened to the Windows Loader, which led to the inability to boot the OS, or due to some kind of problem with the computer's disk. There are a number of other causes, but they are very difficult to determine without the help of a technician.
So, in order to solve the problem and perform most of the methods that will be described below, you need to get yourself a Recovery Disc with an operating system. Windows system, since with the help of it we will try to restore.
To do this, just follow this link to the official Microsoft website and read them official article on the topic "Creating a System Recovery Disc". Once you have the recovery disk in your hands, then proceed to the methods below.
Solution Methods
Method #1 Turn off all peripherals
The following advice may seem rather strange, but some users claim that disconnecting peripherals from their computer, i.e. mice, speakers, gamepads and other non-critical equipment for the system helped them overcome the 0xc000000f error.
This may be due to the fact that the computer has a faulty working driver for a particular device and it does not allow the system to boot normally. Disconnect everything from your PC that is unnecessary to start it (with the possible exception of the monitor) and try to boot into Windows again.
Method #2 Load Last Known Good Configuration
Obviously, the current state of your system is not its most stable state. In this case, you can try a very simple solution - loading the last known good configuration. With this boot option, you can restore your system to its original, working state.
To load Last Known Good Configuration, do the following:
- Restart your computer.
- Until the system enters the boot phase, press the button F8 to enter the Windows Advanced Boot Options Menu.
- Select "Load Last Known Good Configuration (with working settings)" option.
To be honest, this method of solving boot problems rarely brings any results, but it’s worth trying to fix the 0xc000000f error with it.
Method #3 Launch Recovery
The next method will require you to use the already mentioned recovery disk, through which you will need to boot. So, do the following:
- So, to begin with, you will need to boot through the recovery disk. To do this, go into the BIOS and set to the first boot priority not on HDD, but on DVD-RW or flash media (depending on what you used when creating the recovery disc).
- Once you are done with the prioritization, insert the recovery tool into the system and reboot.
- Instead of booting from your hard drive, you will be taken to the Recovery Environment. Choose the language you want to install, time format, currency, and input method. Then click Next.
- Click on the "System Restore" button.
- Choose your operating system and click Next.
- You will see a menu for selecting a recovery tool. Select Startup Repair.
After that, the scanning process will begin and attempts to fix the problems found. Once it is over, restart your computer and check for error 0xc000000f.
Method #4 Restoring the bootloader
As already mentioned at the beginning of the article, error 0xc000000f can be caused by damage Windows bootloader. If this is the cause of the problem, then you can try performing a bootloader repair. To do this, do the following:
- Boot into the Recovery Environment again, as already shown in the previous method.
- Get to the recovery tool selection menu. This time select "Command Prompt".
- Enter the command on the command line bootrec.exe and press Enter.
- You will see a list of Bootrec.exe commands that you can run. We recommend entering the commands bootrec /fixmbr, bootrec /fixboot, bootsect /nt60 ALL /force /mbr, exit by pressing Enter after each one.
After executing these commands, restart your computer and check if the error 0xc000000f is still there while loading Windows.
Method #5 Checking and Fixing Disk Problems Using Hiren's BootCD Utility
This method is already a little more complicated than all the previous ones, relatively. You will need to create another boot disk, but only now with the utility Hiren's BootCD. Given software can check your hard drive and fix problems found on it, if any.
- Follow this link and download latest versionHiren's BootCD. Once you download the utility, you will need to burn it to a disc or USB storage.
- Now you need to boot your system through the burnt disc, just like you did earlier with the Recovery Tool.
- When booting from this disk, the program menu will appear in front of you. Hiren's BootCD. Select Dos Programs.
- Now select the sixth menu item called "Hard Disk Tools ..." (Hard Disk Applications).
- Select the first item named "HDAT2 4.53 (Test/Repair Bad Sectors)".
- The disc menu will appear in front of you. Choose your disk (if you don't know which one is yours, then just start from the volume).
- Now select the option "Check and Repair Bad Sectors" (Find and fix bad sectors).
- After selecting this option, the process of checking your disk will begin. It can last from several minutes to several hours. Wait for it to finish. Once it's completed, set the boot priority in your BIOS to the old value, i.e. first priority to the hard disk, and remove the disk or flash drive from Hiren's BootCD from your computer.
We hope that the methods we have described for you above have helped you deal with error 0xc000000f when booting Windows. If not, then there are two more options left: reinstalling Windows and visiting service center, because something might have happened to your hard drive.

Question: Error 0xc000000f and locked hard drive
Hello. I have Acer laptop TBM113-E-10172G32akk with insydeh20 setup utility rev 3.7. There was a starting OS 7. I decided to install another one. As a result, he messed up in full. It was not possible to install Windows - I did not want to install it in the selected partition. Rummaged on the Internet, converted a hard drive through convert basic. The operating system stopped loading altogether. Writes error 0xc000000f. When I tried to restore Windows, the computer wrote that the disk was locked, unlock it and try again. I read and read, but I didn't find anything about this case. As I did not want to install, it does not install. in the security section, I don’t have anything about disabling the lock.
In the end I had:
1. Error 0xc000000f
2. Locked hard drive
Now I screwed up - I converted the disk to a dynamic format, I can’t even format it through installation flash drive.
I read about blocking that some kind of driver is needed hard drive write to a USB flash drive, but did not figure it out.
Please advise what can be done in this situation. Maybe it was that you had to format the disk right away, and only then try to install it?
Answer: Thanks everyone, problem solved. With life sd converted the disk and formatted it, deleted all partitions.
And then acted as it is written in this article in the paragraph "Installing from a hard disk".

Question: Error code 0xc000000f sadness
In general, the situation is this, it’s useful to clean the percentage of dust, as it should be once every six months. I decided at the same time to change the thermal paste on the video card and processor. In the process, I turned off only the video card and pulled out the chip, respectively, turning off the cooler from cooling. After I put everything back together, the computer didn't boot up anymore. Appears blue screen with Recovery (Your PC failed to boot correctly - A required device is not connected or not available - Error code: 0xc000000f) If you continue it hangs on boot, if the blue screen does not appear (this happens sometimes on reboot) it also hangs on boot. The system also hangs on loading if you select one of the suggested boot options. When you try to reinstall windows from a flash drive, the same hang.
Two days combing the forums did not find a solution to my problem, but I tried a lot. It all comes down to the fact that there may be a problem with hard drive. But this is strange, since it is fresh and did not even turn off by me. The disk is visible in the bios. Worth Windows 10
There is a lot of information on study on the computer, I tear the hair on my head! Help, who fumbles please!
Answer: No, the screen is bluish. Like here, only without any specific error. There is no inscription other than in my link, not boot\bcd

Question: Error 0xc000000f \Boot\BCD after manipulating Bootrec.exe
It all started with a constant boot Windows in recovery mode. I found a topic in which it is proposed to fix this using commands in system recovery mode via the installation disk:
bootrec.exe
Bootrec.exe /FixMbr
Bootrec.exe /FixBoot
bootsect /NT60 SYS
Bootrec.exe /ScanOs
Bootrec.exe /RebuildBcd
but after I did this step from the installation disk, I realized that I missed one moment. Select your OS from the wishlist. the list was simply empty.

I decided to reboot - I got it eternal loading in recovery mode) Help, please. Thank you
Answer: In general, the problem was not solved in any way. Just reinstalled Windows. To hell with this JD.
Question: Complete collapse system 0xc000000f 0x80070005
I have set myself enough old version one program. Mathcad 14, to be exact. This program did not function as I expected, so I tried to correct its work. The program contained the Fix problems utility, which, as I understood it, reconfigured the registry. Using the utility did not improve the program's performance in any way, so I quietly uninstalled the program and rebooted the computer to "return everything as it was." However, life is cruel and, often, to return everything, as it was, is impossible.
After the reboot, the OS did not boot, with the error "The operating system could not be loaded because the NLS data is missing or contains errors. Error code 0xc000000f". I had a laptop at hand, so it was not difficult for me to make a bootable USB flash drive with windows 10.
First I tried to rollback to an earlier version, to my delight there were 7 options on the list with a total time span of 2 weeks. However, in this list, unfortunately, there was no option to roll back the system to the moment Before using the fatal utility that fixed my registry (I mean there were earlier points in time, but it is important that those restore points are in no way associated with a change in the registry, and therefore the registry would not be restored), there were only "cosmetic" options Before and After installations different programs. None of the possible restore points worked, giving the error: "Unexpected error while restoring system 0x80070005". Next, I tried to do a boot repair, another error. Return to the previous assembly, restoring the system image is also by. I had the highest hopes for being able to return the computer to the initial state with saving personal data, but the process was interrupted at 1% with the message "There was a problem while restoring your computer. No changes were made." For reinstall windows requires access to a running OS, which obviously does not exist. Thus, I tried all the options for restoring the system without deleting personal data, except for using command line when starting from a flash drive and bios settings.
The options to delete personal data would most likely solve my problem, however, my PC is a monoblock, disassemble it to get the hard drive and transfer it from it important information, quite problematic, besides, I don’t have other system units, only laptops, so it’s still not clear where I could connect this hard drive. Therefore, I would like to find a solution to my problem "with the preservation of personal data."
P.S In the BIOS, in the Hard Disk Drive Priority option, there is only one choice "P1: ST3500413AS" (well, after connecting bootable flash drive there was obviously another choice with this very flash drive), which confuses and alarms me.
Answer: vavun, thanks, I restored access to the OS in half an hour. It is significant enough that third-party lifeCDs weighing hundreds of megabytes turn out to be many times more useful than official GB recovery tools, it seems that microsoft is not trying at all.
Consider another common Windows 10/8 boot error caused by file corruption or missing winload.efi. The problem manifests itself as follows: Windows 10 (Windows 8.1) stops loading, usually with a BSOD, with the following error in the recovery console:
Recovery
Your PC needs to be repaired
The application or operating system couldn't be loaded because a required file is missing or contains errors.
File: \Windows\system32\winload.efi
Error code: 0xc000000f
You'll need to use the recovery tools on your installation media. If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer.
Press Enter to try again
Press F8 for Startup Settings
Press ESC for UEFI Firmware Settings
Note. The error code can also be: Error code: 0xc0000225 or 0xc0000001.
In the Russian version windows error looks like that:
Your computer needs to be restored
The application or operating system could not be loaded because a required file is missing or contains errors
FILE \Windows\system32\winload.efi
Error code 0xc0000225
You will need the recovery media on the installation media. If you don't have installation media (such as a disc or USB device), contact your administrator or computer manufacturer.
The appearance of such an error is due to the absence or damage to the structure of the system boot file - \windows\system32\winload.efi. As a rule, the problem can occur after performing an incorrect system update, if the disk is damaged, or file system, when repartitioning the disk with third-party utilities, updating the antivirus, after transferring the OS image to another disk, replacing motherboard computer and other interventions.
File winload.efi is an EFI executable with a bootloader that initializes the environment and starts Windows boot. In the event that this file is corrupted, missing, or the boot configuration specifies the path to a non-existent volume with the winload.efi file, Windows cannot boot.
The solution to the problem depends on whether you were using UEFI or Legacy boot mode before the problem occurred. Here are the basic steps to help you fix given error and load Windows 10 / Windows 8.1 correctly.
Enable CSM compatibility mode and disable Secure Boot
Most UEFI-enabled computers can boot from both UEFI disks and legacy MBR disks in Legacy mode.
Reboot the system and enter the UEFI setup menu. The key to enter the UEFI menu depends on the computer manufacturer, as a rule, these are keys F2, F8 Del or Esc. Or press the ESC button directly on the screen with an error.
Automatic System Restore
Try fixing the error with Automatic System Repair. For this:
If you do not have a Windows installation disc at hand, you should restart the computer by pressing the Power button three times until the Recovery Console screen appears. Select an item Seeadvancedrepairoptions (Additional Options recovery). Further, everything is similar.
Disable the ELAM security feature
Boot from boot disk and run command line:
