One user, referred to as sai, provided a solution involving Apple's official support recommendation. After contacting Apple, he was advised to use the cmd r method during boot to format the disk and then install OS X Yosemite from there. While this method served its purpose, it required downloading OS X Yosemite again if not already installed, which might not be convenient for everyone.
