Enter safe mode to uninstall the update, roll back the driver or uninstall the interfering software; 2. Use the system restore to fall back to the pre-update state; 3. Run the chkdsk and sfc commands to repair the disk and system files; 4. Finally, you can try to reset or repair the installation of Windows. When encountering a startup cycle, try the above methods in turn to avoid directly reinstalling the system.
After the update is installed, Windows enters the boot loop, which is actually uncommon, especially when the system file is corrupted, driver conflicts, or the update itself is incorrect. If you are encountering this problem, don’t rush to reinstall the system first. The following common reasons and response methods can help you gradually investigate.

1. Try to enter safe mode to troubleshoot problems
When encountering a startup loop, the first step is to try to enter safe mode . This is one of the most commonly used methods to troubleshoot system problems.
- Press F8 or Shift F8 repeatedly when the computer is just turned on (some new models need to enable the traditional startup menu in the BIOS)
- If it doesn't work, you can trigger the "Auto Repair" interface by force shutting down three times, and then select "Troubleshooting → Advanced Options → Start Repair"
Once in Safe Mode, you can:

- Uninstall the most recently installed updates
- Roll back or disable the problematic driver (especially graphics card, motherboard driver)
- Check whether there are third-party antivirus software or optimization tools that interfere with startup
2. Use the system restore point to fall back to the pre-update state
If problems occur after the update, using system restore is the most direct and effective way.
- Find "System Restore" in "Troubleshooting"
- After logging in, select a restore point before update to return
Notice:

- System restoration is only enabled on disk C by default, and other partitions will not be backed up.
- The restore process will not affect your personal files, but may affect recently installed software and settings.
3. Check hard disk errors and system file integrity
Sometimes the system update fails because the disk has bad channels or the critical system files are corrupted. At this time, you can use the following two commands to check:
Run in "Troubleshooting → Advanced Options → Command Prompt":
chkdsk /f /r
This command checks and fixes disk errors and may require a restart to complete.
Then run:
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
This scans and repairs system files. If corrupt files are found, the system will attempt to recover from the installation source.
4. Reset or repair installation of Windows
If none of the above methods work, the last way is to reset the computer or repair and install it .
- "Troubleshooting → Reset this PC" You can choose to keep the file or clear it completely before reinstalling
- If you have installation media, you can also boot from the USB flash drive and select "Upgrade Install" to preserve most settings and applications
The benefits of repairing installation are:
- Do not delete user data
- System components can be repaired without installing them from scratch
Basically these common ways of handling it. Although starting a loop is annoying, it can be done in most cases with safe mode, system restore or repair commands. The key is not to format and reinstall it as soon as it comes out, as it will take too time.
