I’m at window 10, where is the option to boot to the recoveryWhat OS are you on? You should try to boot from Safe Mode or USB Stick 16GB or higher running Windows PE or WinPE. There are some other versions of PE online you can try as well. You'll need a friends PC too build a Windows PE USB stick so you can boot to that stick and fix your damage OS which hopefully was Windows OS. If on Windows 10 you have option to boot to the recovery mode where you last good copy of Windows could be restored.
