Windows unable to boot after edge update with .msi file

The error message "INACCESSIBLE_BOOT_DEVICE" typically indicates that Windows cannot access the system partition during the boot process. This can occur due to various reasons, including corrupted drivers, changes in the storage controller settings, or issues with the file system.

Since you mentioned that you are unable to uninstall the Edge update using the command prompt and received an error about the Windows Installer Service, it suggests that the system is in a compromised state. Here are some steps you can take to troubleshoot the issue:

1. Boot into Windows Recovery Environment (WinRE): You can do this by using Windows installation media. Insert the media, boot from it, and select "Repair your computer."
2. Run Startup Repair: In the WinRE, navigate to Troubleshoot > Advanced options > Startup Repair. This tool can automatically fix some startup issues.
3. Check Disk for Errors: If Startup Repair does not resolve the issue, you can run a check disk command. From the command prompt in WinRE, execute:

      chkdsk /f /r
   

   This command checks for file system errors and attempts to repair them.
4. System File Checker: If you suspect that system files are corrupted, you can run the System File Checker tool. From the command prompt, execute:

      SFC /Scannow /OffBootDir=C:\ /OffWinDir=C:\Windows
   

5. Restore Registry Hive: If the problem is related to a corrupted registry hive, you may need to restore it from the RegBack folder. This involves navigating to C:\Windows\System32\config\RegBack and copying the files back to C:\Windows\System32\config.

If these steps do not resolve the issue, you may need to consider performing a system restore or reinstalling Windows as a last resort.

It is very strange if that Edge installer caused Windows not to boot up correctly.

1

In the recovery environment, try performing a System restore to a date prior to the problem starting, if that is not available or not successful, try uninstalling the latest update.

2

If you still cannot boot up Windows, in the recovery environment open Command Prompt.

Run this command and press Enter.

bootrec /FixMbr

Run this command and press Enter.

bootrec /FixBoot

Run this command and press Enter.

bootrec /ScanOs

Run this command and press Enter.

bootrec /RebuildBcd

Then reboot your System to see if Windows will boot up normally.
