Hi Hikari. I'm Greg, an installation specialist and 9 year Windows MVP here to help you.
A Reset or Refresh will use the Windows 10 image file stored on board to reinstall Windows 10. Only if you run the PC maker's Factory Recovery (which will be labeled that clearly) will it reinstall Windows 8.1 which is not desirable.
The Reset may have been customized by your PC maker to restore all the preinstalled bloatware. So the Fresh Start leaves out the bloatware and only reinstalls the MS Store apps.
You can study the differences here:

Refresh: https://www.techrepublic.com/article/how-to-use...
Finally, the quality of the install in Windows 10 is hugely important and the very best install is the Clean Install which should get you past all difficulties as it has hundreds of thousands of others who have followed the steps in this link and never come back to report another problem: http://answers.microsoft.com/en-us/windows/wiki.... You can look over the steps which are quite a bit more involved than the automated methods I mentioned first.
I hope this helps. Feel free to ask back any questions and keep me posted. If you'll wait to rate whether my post helped you, I will keep working with you until it's resolved.
