Hello,

Thank you for your response.

I appreciate your patience.

Did you try using suggestions provided in the previous posts?

If not, please use those suggestions and reply with results.

If issue still persists, I would suggest you to run this Microsoft fixit and check.

Refer:

    Hello Priyam,

    Thank you for your response.

    I appreciate your time and patience.

    I would suggest you to disable secure boot in BIOS and then try the commands again.

    Note: Modifying BIOS/ complementary metal oxide semiconductor (CMOS) settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of BIOS/CMOS settings can be solved. Modifications of the settings are at your own risk.

    I hope this information helps.

    Thank you
