One time Windows 10 wiped the boot loader on my desktop and threw a fit until I formatted the whole disk so it could place itself first unlike the partition I thought I had assigned it. Then I reinstalled windows 10 on the same computer a couple of years later and the installer couldn't even format my drive to install it, just threw bland "not working" errors until I manually formatted and installed the windows bootloader from a rescue drive. What's your point?
