How to remove windows 10 from dual boot after bootcamp?

Question

macOS

Hello.
I recently installed Windows 10 using Bootcamp and then deleted it via Disk Utility (deleted the partition on the disk for Windows), but if I hold down the option when I turn it on, then I see Windows 10 (that is, I can boot it, although I deleted it).
Question: how to remove it completely?

Answer 1

Try to register in the terminal diskutil list
If there is a partition associated with BootCamp / Windows in the list, then you can delete it with the command diskutil umountDisk /dev/diskX, where "X" is the disk number
