dualboot hackintosh remove

I have installed hackintosh with dual boot on my windows laptop and it worked but eventually it had a lot of problems but the main one is not being able to boot into the boot picker window. It only works if the pendrive i used for installation is pluged in to the laptop. I want to remove dualboot opencore and hackintosh from my laptop. How can I do it without needing to perform a clean install and lose my data?
