Suvana,
Thank you for your quick reply/answer to my question.  Could you let me know how I would be able to download the McAfee removal program if my PC does not start?  FYI, every time I try to restart, I continue getting the same error message previously referenced in my original post...so at this time I can't even get to the start button.  

Again thank you for your help.

Hi,

Thank you for your reply.

I suggest you to try performing a startup repair using an installation media and check if it helps.

Follow the steps given below.

1. On a working PC, go to the Microsoft software download website.

2. Download the media creation tool and then run it. 

3. Select Create installation media for another PC.

4. Choose a language, edition, and architecture (64-bit or 32-bit).

5. Follow the steps to create installation media, and then select Finish.

6. Connect the installation media you created to your nonfunctional PC, and then turn it on.

7. On the initial setup screen, enter your language and other preferences, and then select Next. If you're not seeing the setup screen, your PC might not be set up to boot from a drive. Check your PC manufacturer's website for info on how to change your PC's boot order, and then try again.

8. Select Repair your computer.

9. On the Choose an option screen, select Troubleshoot > Advanced options > Startup Repair.
