I was gifted a windows computer which functioned well apart from a failed hard drive. I removed the hard drive and drilled holes through it as it had medical information on it and I didn't want to violate HIPPA. I installed a new SSD drive that I was careful to select based on compatibility. The computer after turning on tells me that no boot disk can be detected which I am aware means that it cannot read windows. How can I reinstall windows on this machine without repurchasing a license. I have the product key for the current windows install if that helps.
