I legit just physically disconnect the drives with other operating systems while installing Windows in dual boot situations. Can't break what isn't there!
That worked with MBR boot, but with UEFI, Windows will notice you have Boot* variables in motherboard NVRAM pointing to a Linux install that doesn't exist, then clear them for you.
Sometimes very necessary. Windows 7 had a bug that caused it to spread boot information across multiple drives if you had more than one plugged in at install time, even if you specified only to use one.
