cant refresh pc from iso

[Andrewthegreat]

my windows 10 pc is failing to boot. i made a windows 10 usb, and tried everything in troubleshooting, including the upgrade option, but none of those options would work unless my windows pc didn't need repairing. all i want to do is refresh the pc, but that option isn't there.
can someone help? i would like to try and keep all my files.
thanks in advance

So troubleshooting/reset this PC doesn't work?

ONe way to save files is this:
boot from installer, on 2nd screen after languages, choose repair this pc, not install
choose troubleshoot
choose advanced
choose command prompt

I typed notepad in which obviously opened the notepad. From there I went to file > open which opened a file explorer. I plugged an external hard drive into my USB port, and I searched for all of my most irreplaceable files and copied them onto the external drive, then once I finished, I plugged my drive into my Mac and confirmed that all the files are all there.

If you can save copies of all your files, I would suggest a clean install if reset doesn't work
boot from installer
follow this guide: http://www.tenforums.com/tutorials/1950-windows-10-clean-install.html

when you reach the screen asking for licence, click "I don't have a key" and win 10 will continue to install and reactivate once finished

On the screen where you choose where to install win 10, if it gives you an error about GPT drives, delete all the partitions on the hdd and press next. If it still gives error, cancel out of the installer and restart PC and start installer again, it will accept next on that screen this time (some PC just need a restart here).
