On startup I have to choose which OS I want.

On my laptop my OS is Windows 10 and only Windows 10. When I first bought the laptop it has Windows 7 installed. I then did a clean install of Windows 8 when it came out. This past July I did a clean install of Windows 10. A few weeks ago I kept getting the blue screen of death so I again I did a clean install of 10. That is I did it in such a way as to format everything on my hard drive and reinstall Windows 10. I’m having no problems now except for the fact that whenever I restart it gives me an option of choosing Windows 10 or Windows 7. Win10 is set as the default and I don’t even have Win7. Can anyone think of a reason why it gives me that option?

This probably has nothing to do with your issue. But, no harm making sure.....................

In your search box, type msconfig > Enter.
Click Boot tab at the top.
Do you see just your Win 10 listed or do you also see Win 7 listed ?
If you see both, click Win 7 > click Delete > click OK when done.

Thank you. I did that and did see Windows 7 which I deleted and then clicked on "Apply". I no longer have to choose as it boots right into Win 10.
