    blue screen showing 0XC000021a


    For the second time I have an problem that my NVME-M2 Westerndigital black PC SN700, is not accessible for booting Win10, it show only a greyed Localdisk symbol and an NTFS remark.
    I have solved this by using this Youtube video:
    It became now accessible but still I could not boot, it did show the 0XC000021a failure, the created SRT logfile is in the attachment.
    CHKDSK and the SMART test from Westerndigital tool did not show any problem.
    To avoid conflicting the other boot SSD and data HD I did disconnect these and after reading here, I went for the DISM.exe /Online /Cleanup-image /Restorehealth and SFC /scannow commando. Which did delete most of my software :-(
    BTW I have also the CBS file included


    Resetting or back to an restore point could not be performed, I know from the first time I had to reinstall Win10pro-1903 complete.
    Reinstallation is not the problem as all the software is already been gone by that DISM/SFC commando, but what is more important for me, what is going on, at my system, for the future how to repair this easily without deleting all my software/programs and how to avoid this 0XC000021a.

    Thanks and I do hope a member could figure this out.
