Fix 1 – Reset the changes in BIOS

Step 1 – To do this, restart your computer.

Step 2 – As soon as the screen lights up, check which key leads to the BIOS page. Tap and hold the key to open the BIOS menu.

You may not be able to do this on the first try. But, restart and try to access the BIOS page.

You have to force reboot the system to reach the Windows Diagnostics.

Step 1 – Restart the system. As soon as the system boots up, shut it down again using the power button.

Step 2 – Repeat this process twice more and let the system boot up on the third try.

Step 3 – It will open up the Automatic Repair mode.

Step 4 – Next, tap the “Troubleshoot” option there.

Step 9 – Now, you have to rename the bcd file and rebuild a new bcd file in its place.

bootrec /rebuildbcd

When this asks the question “Add installation to boot list?“, write the “A” button and hit Enter to select the All option.


This will return this message –

The operation completed successfully.


After this, just close the CMD terminal shell. Coming back to the main Windows page, tap “Continue” to continue to the normal PC environment.


Fix 3 – Disable new device

Have the system gone into the Blue Screen of Death mode as soon as a new device is connected? The driver incompatibility can lead to this issue.

So, we suggest you to eject any new device that you have connected to the system, prior the BSOD error message and test.

If the BSOD error doesn’t appear further, the device that you have connected is to blame here.


Fix 4 – Uninstall the newly installed apps

Sometime, it isn’t devices, but a an third-party app that can cause this issue.

Step 1 – To do this, hold the Win+R key combinations.

Step 2 – Next, paste this in the Run dialog box and hit “OK“.
