How to install windows? Boot loop

Hello, I accidently turned off my computer during installing windows. I followed the instructions at Fix: 'The computer restarted unexpectedly' loop on Windows 10 I changed the registry from 1 to 3 as it said to do. At first I was getting a boot loop of 'The computer restarted unexpectedly' error message, but after doing the registry fix, it now boots without any error, and keeps restarting in a loop.

How can I reinstall windows? I did the reset your PC option.

Thanks! =)

Boot from a Windows 10 installation USB flash drive or DVD, wipe the HDD or SSD and start over?

Download Windows 10

Thanks. I'll try that. I don't know where to find my windows 10 serial key though. Is there any way to recover it before I try to re-install windows?

If you install the same version of Windows 10 on the computer that was activated on it before, you won't need a product key. When setup asks for a product key, click the little link that says "I don't have a product key."
