Good description of the process, but... /rant on Sigh. Somehow it's still quite easy to screw up, intentionally or not, your boot system. But every X years the boot system is completely overhauled, so over time I learned how to deal with fdisk /mbr, lilo, grub, grub2, ntldr, bootmgr/bcd... That's a lot of info to memorize for something you would really prefer not to know, and that I honestly need somewhat rarely.
