So my Windows 10 PC has stopped connecting to the internet (It still connects to the modem) and after days of trying to solve the issue, I haven't found a single solution. The error I get is: One or more network protocols are missing on this computer Alternatively, I get a different error sometimes saying something about the DNS not being able to register, or something like that. I've tried every single 'solution' that googling my problem has to offer and it's done nothing. So I'm either looking for a way to fix this, or I just want to format the whole thing and get rid of this headache of a problem. So, if I can't fix it and have to format, since I have a genuine Windows 10, will my 8.1 key that came with my PC do the trick when it comes to activating it? I don't want to run a pirated windows, they always cause me trouble. I've also always wanted to run a dual OS with Linux (probably Debian, but I'm not very familiar with the differences). Since I'll be starting fresh I feel like this would be the perfect time to do this, but I have no idea how to set this up, and when I tried on my laptop I ended up giving up because it wasn't working right. TL;DR: How do I fix my internet, and if I can't what's an easy way to re-install Windows from scratch, preferable with a dual-boot option with Debian Linux?
