- Somehow two of my PC and laptop cannot boot after installed Windows Update, somewhat related to 1803 version.
- First my PC got boot corrupted.
- So I burn Windows 10 ISO to USB, boot from USB, select REPAIR > TROUBLESHOOT > COMMAND PROMPT.
- I have multiple HDD and Windows on my PC.
- And I found out that, after installed updates related to 1803, boot sector/configuration is corrupted, the main Windows folder that I use is not in the boot list anymore.
- So the boot list is corrupted.
- First, I identify which volume is my Windows folder using DISKPART and make it active.
- You can google "windows 10 bootmgr missing", "windows 10 bcdboot repair", "windows 10 bootrec fixboot" and so on.
- Using DISKPART, I use LIST DISK, LIST PARTITION, LIST VOLUME, SELECT VOLUME, ACTIVE then EXIT.
- My missing Windows folder is D:\Windows.
- I try using BOOTREC /FIXMBR, then BOOTREC /FIXBOOT, but FIXBOOT give me error message either "ELEMENT NOT FOUND" or "ACCESS DENIED".
- So I go to folder "D:\EFI\MICROSOFT\BOOT", rename the current BCD to remove it using "REN BCD BCD.BAK".
- Then I use "BCDBOOT D:\Windows \l en-us \ s d: \f ALL"
- Then I use "BOOTREC /SCANOS", then "BOOTREC /REBUILDBCD"
- Then I restart my computer.
- Make sure first boot HDD is the HDD that you want to load the Windows.
- So because I don't want anymore Windows Update on Windows 10, I googled and found article on "How to Disable Windows 10 Update in Every Way" from EaseUS (https://www.easeus.com/todo-backup-resource/how-to-stop-windows-10-from-automatically-update.html#part1)
- I use "SERVICES.MSC" > Windows Update > Disabled.
- Then I use "GPEDIT.MSC" > Computer Configuration > Administrative Templates > Windows Components > Windows Update > Configure Automatic Updates > Disabled.
Windows 10 is great but the forced upgrades are ridiculous. As far as I can tell there is no known way to permanently disable the updates. If you disable the update service, there are scheduled tasks that run regularly to re-enable them. If you cancel the scheduled tasks, as soon as you reboot your computer they get added back. The possible solution is that there should be a registry key you can set to alert you that windows 10 updates are available instead of automatically installing them.
