Reinstalling windows 10

Hey All!

Recently I’ve been having a lot of problems with my PC, which all started with the error “boot files are missing”. To fix this I have tried many things such as renaming volumes and using installation media, however to no avail.

Hence, I decided I would Format C my hard drive after backing it up. I installed linux to access my files however half the files come up – why is this? The only files that show up are ones about Windows 10 and temp logs etc.

Furthermore, its come to my attention that I might lose my version on Windows 10 and am curious on how I should reinstall it correctly, so i keep my genuine version of Windows 10 (I upgraded it from Windows 7.)”

Thank you!
