Windows 10: "Boot Device Not Found" Due to Update: November 10, 2020—KB4586781

Experiencing "Boot Device Not Found" error on restart after install of KB4586781. Full shut down and start performs boot normally. UEFI disk test results in "pass" for disk drive.


Fresh Windows reinstall and troubleshooting with temp removal of KB4586781 fixes problem. This seems to indicate conflict with that update. Unfortunately, removal is only temporary as Windows eventually forces the update install.


All computer firmware and drivers up to date. PC manufacturer advises this is a Windows issue. Any suggestions on how to resolve?

Windows 10 November update

Hi,

Welcome to Microsoft Community and thank you for posting your query.

Let me help you to fix the issue.

Since, you are using dual boot the November update might get installed on the previous version of the Insider Build 10567 due to the Operating system version partition is set to default. I would suggest you to go to the System configuration and check.

• 
  Press Windows Key + R, type msconfig on the box and press
  enter.
  
• Now click on the Boot tab and check which Operating system version is set to the default.

If you want to update the 10240 July Release, follow the above steps and set as default Operating system and try updating it.
