Well, creating a bootable Windows USB was quite complex, but today it’s very simple or easy. Head over to Microsoft’s website, then install the Media Creation Tool. Then run it as administrator. For this part, you want a USB with a minimum of 8 GB and a working Windows PC.

  • When the tool begins, choose “Create installation media for another PC” and then tap “Next.”
  • From the next screen, check the edition, language, and architecture the same as on your PC.
  • Then choose the “USB flash drive” option and then move to the other section.
  • You will then view a list of plugged USB drives where you would like to choose the USB that you wish to make bootable. Then tap “Next” and wait until the installation process ends. However, the process takes few minutes. Well, it depends on the internet speed and the transfer speed of the USB.

When your bootable USB is done, you can move further with resolving your boot configuration data. Well, the first few steps will be quite similar to install a fresh set of Windows. Keep in mind that none of your data will be lost, you will only be resolving what is “broken.”

  • Simply connect your USB and turn on your PC.
  • During the POST, just head over to the BIOS and change the priority of the boot order, or else you can select a temporary boot drive.
  • For the exact method, you want to check your laptop user manual or motherboard, since most have a different way of doing that.
  • After a few minutes, the Windows wizard will begin where you want to select the language, time and currency format, and keyboard layout. In some situations, just leave these by default.
  • From the other screen, tap on “Repair your computer.”
  • Then head over to the next menu, choose “Troubleshoot.”
  • From the troubleshooting options, tap on “Advanced options.”
  • Now from the advanced options, select “Command Prompt.”
  • Bootrec.exe is no doubt an efficient tool to resolve boot error. You need three commands that you want to enter to resolve the issues regarding BCD:
    • bootrec.exe /fixmbr
    • bootrec.exe /fixboot
    • bootrec.exe /scanos
    • bootrec.exe /rebuildbcd

For the last command, a prompt appears asking you if you like to add the found installation to boot, where you will enter “Y” and then press enter. If you still find the issue the dive down below to fix BCD errors:

Active partition

An inactive partition on your drive is another reason for the similar BCD error, so it is the best idea to check if the right one is active.

Follow the same instructions as mentioned above to get to the Command Prompt, where you want to input a series of commands:

  • diskpart
  • list disk
  • choose disk X (replace X with the number of the drive where Windows is installed)

Hardware Issue To Fix BCD Errors:

If you wish to boot your Windows, then head over to Command Prompt. Or else you can use the same method just like the other two methods in this article. Input in the command “chkdsk C: /f /r” and the process complete. In case, if Windows is installed on a different partition, labeled E or D, make sure to modify the letter accordingly. It will then scan the disk and try to resolve any errors that it can. Once it completes, you will then view a report highlighting the details.

Rather than HDD or SSD, a corrupt RAM stick may also be the reason for the problem, and you might want to have your power supply checked out, but before you move down that road, you can first check the disk.
