How to fix the blue screen 0x7B INACCESSIBLE_BOOT_DEVICE after updating on Windows 10

Many users have encountered a stop error or a blue screen error 0x7B INACCESSIBLE_BOOT_DEVICE after using Windows Updates to update on Windows 10/8/7. Microsoft has released a number of solutions to help users solve this problem.

This blue screen error is caused by a boot flaw caused by device driver and data collapse. Sometimes it may be due to hardware or virus. Therefore, you will receive a 0x0000007B error message on the blue screen of death or a stop error.

Even if Windows crashes, you get the message “Windows has recovered from an unexpected shutdown” and this problem can occur with all versions of Windows. Before attempting to perform the below measures, try restarting your computer, sometimes this simple reboot may fix the problem.

1. Make changes in the hard drive driver

If you have recently made a change in the hard drive driver, this may be the cause of the blue screen error, so please make these changes again.

  1. Use System Restore.
  2. Configure the new hard drive driver.
  3. Remove the new hard drive driver if the configuration does not work and you do not need it.
  4. Starts with Last Known Good Configuration mode to undo the registry and restore driver changes.
  5. Return to the hard drive driver and device driver before updating the driver.

All of these measures can correct or not correct the blue screen error depending on the cause of the error. However, if this solution does not work, at least you will know that the hard drive controller does not have to be the cause of the error.

2. Check the settings

Make sure the hard drive is properly installed, if not installing any new devices recently, bypassing this method.

3. Check the BIOS configuration

Make sure your hard drive is configured correctly in the BIOS.

4. Scan the virus

If the antivirus software detects a problem, follow the software’s support and restart the computer. Users should keep their antivirus software up-to-date and scan their computer regularly to prevent this from happening.

5. Update driver

The driver of the old hard drive driver may be the cause of the blue screen error, so please update the driver. Read the article 5 Basic Ways to Update, Update Your PC Driver To Know How To Update Your Hard Drive Driver.

Some advanced SATA features may cause this error. Change the SATA (AHCI) mode to IDE (ATA or Compatibility Mode). In some older versions, trying to delete CMOS can also fix the problem.

7. Run chkdsk

If the boot partition is corrupted, running chkdsk on the hard drive will solve the problem. You may have to run chkdsk from the Recovery Console.

8. Hard drive failure

If your hard drive is faulty, you should replace it. See the article that shows you should replace your hard drive to see if your hard drive is experiencing these problems.
