How to fix "Your pc ran into a problem and needs to restart" after system update

The Command Prompt repair method is a quick way to resolve boot failures without the need for additional software.

By repairing the Master Boot Record, resolving disk errors, and restoring corrupted system files, this method can typically resolve common boot issues in just a few minutes, thereby immediately eliminating the root cause of the error and restoring Windows to normal operation.

First, open the Advanced Options screen. Select Troubleshoot → Advanced Options → Command Prompt. Then, run the following commands in order:

# Fix boot configuration
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

# Check and repair disk
chkdsk c: /f /r /x

# Repair system files (if accessible)
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows

Once all commands have been executed, type “exit” and restart your computer. This method requires no additional tools and can quickly and thoroughly resolve issues causing the error Your device ran into a problem and needs to restart, effectively restoring your computer's normal startup functionality.

It is particularly useful for fixing boot loop issues, repairing damaged MBR or BCD, resolving disk corruption, or troubleshooting startup failures where Windows repeatedly crashes and shows the restart error.
