Hello,
Thank you for posting in Microsoft Q&A.
Based on the description, I understand your question is related to no boot after an update.
Restart the computer, press and hold the F8 key as your computer restarts. The machine will show advanced boot options.
Select Repair your computer/Troubleshoot, and then click Advanced Options, choose Uninstall Updates menu option, select Uninstall Updates. The screen will prompt to uninstall the latest update.
After that try reboot the machine and check the result.
Have a nice day.
Best Regards,
Molly
