How do I fix the Windows boot error 0xc000000f?

Windows 10 is still one of the most popular operating systems out there, but it does come with some problems. One of those issues is the dreaded “0xC000000F” error code. This error usually occurs because of hardware failure, such as a faulty hard disk or RAM module. Luckily, you don’t need to pay hundreds of dollars to replace your motherboard just to solve this issue. You can easily repair it yourself, without even having to buy a replacement part. Here are the steps involved in repairing this problem.

1. Make sure that you’ve backed up everything important on your PC. If anything goes wrong during the process, you’ll lose data.

2. Shut down your system completely. Then unplug all peripherals, including monitors, keyboards, mice, printers, etc.

3. Disconnect the power cord from your device.

2. Repair BOOTMGR using a bootable USB drive

Bootmgr is a file located in the Windows directory that contains information about the operating system and drivers needed to start up the computer. If you are unable to access your desktop, it could be because Bootmgr is missing. To fix this problem, follow these steps:

2. Open Disk Management. You can do this by pressing Win+R keys together and typing diskmgmt.msc.

3. Locate the partition where Windows is installed. Right-click on the partition and select “Repair”. This will open the System Configuration Utility. Click on “Startup Repair”, and then press Next.

4. Follow the instructions on screen to continue repairing the startup files. Once completed, restart your computer.

5. After rebooting, logon to your account.

3. Check your data cables

Unplug all HDD data cables (if there are any) before connecting them again. Write down all current BIOS Settings. To check the boot order press the F2 key while your PC boots up. Your computer might be having trouble because of an issue with its hardware; try to change some settings in order to fix it. This will help you to resolve the problem faster.

Frequently Asked Questions

A BCD file is a crucial part of a Windows computer. This article explains how to recover a damaged one.

Old Data Cables Can Lead To Boot Problems

If you use an older version of Windows, there might be old data cables inside your machine. These cables connect USB devices such as keyboards, mice, printers, and external hard drives to the motherboard. If these cables aren’t properly disconnected, they could cause a problem during startup. For example, if you plug in a mouse while Windows is loading, it won’t work because the OS needs to read information about the device.
