Windows 10 not responding to boot device errors.
Windows 10 not responding to boot device errors.
The UEFI partition could be damaged? Have you attempted fixing it using a Windows 10 USB drive?
Thanks for your response! I've started with a backup copy of the entire Win10 SSD and will attempt some fixes found through recovery CMD. This issue seems to have been common in 2018 because of certain faulty Windows 10 updates. Some users managed to restore their system by uninstalling updates one by one or using manually applied registry backups. I'll follow up once I resolve it, hoping others facing the same problem can benefit from my update.
Recent changes, the DISM tools didn’t remove the newest updates for me. Restoring a registry backup only triggered a Windows 10 recovery screen. I’m exhausted except for a full reinstall. I’ve observed something interesting—I restarted into Windows 7 and mounted my Windows 10 SSD to perform a manual file copy to an external HDD, plus the existing backup image. Simply accessing the Windows 10 SSD with CTRL+A, CTRL+C, CTRL+V on the backup drive shows a "Copying files..." window that appears briefly before vanishing without any error. I need to use xcopy with specific flags to transfer files, but some remain inaccessible, reporting "The system can't access the file." This usually occurs with UWP app files. It seems typical?
I resolved the problem by following these steps. With some assistance, I managed to repair the Windows 10 installation. The issue stemmed from two recent updates that occasionally prevented the boot drive from mounting, leading to a frequent BSOD. First, attempt a crash-boot a few times; the next start should launch the Windows 10 Recovery setup. From there, choose troubleshooting options and open a command prompt. Type C to switch to your operating system drive—this might be another letter, but C is common. Use DIR to confirm the drive you're on. On the OS drive, create a temporary folder with mkdir temp to expand working space. Check if the problematic updates are present by running DISM /image:c: /scratchdir:c:\temp /get-packages. Even after multiple reboots, the same fixes applied. Next, uninstall the offending updates directly. Start with the 1.6 update using DISM /image:c: /scratchdir:c:\temp /remove-package Package_for_RollupFix~31bf3856ad364e35~amd64~~16299.248.1.17. If that fails, proceed to remove the 1.6 package itself. On a second machine, download the correct update from Microsoft and extract it with CMD. Install the .msu file into a new folder, then transfer it to your damaged PC via USB. Reboot into Recovery and follow the instructions carefully. After installation, wait for Windows to boot normally but avoid immediate reboots. Create a System Restore before rebooting again, then remove the 1.17 update package. Disconnect any network cables or Wi-Fi, restart, and Windows should launch without issues. Finally, uninstall the remaining 1.6 update from the recovery environment and ensure all updates are applied correctly.
