Remove Windows 10 from 18.04 desktop boot menu

Question

I replaced a copy of Windows 10 with Ubuntu 18.04 desktop successfully. The only problem that remains is that the Windows 10 boot selection entry still appears. I know that disabling the OS probe will work around the problem but I would prefer to get rid of whatever is causing OS probe to think that Windows 10 is still there.

EDIT: I am going the other way than what was suggested in the comment. I overwrote the Windows partition with an ext4 bootable partition.

Any ideas on how to do this?

If UEFI probably this: http://askubuntu.com/questions/63610/how-do-i-remove-ubuntu-in-the-bios-boot-menu-uefi, you have to remove the /EFI/Microsoft folder in ESP and Windows boot entry in UEFI with efibootmgr. — oldfred, Aug 15 '18 at 03:40

First list your boot entries:

$ efibootmgr
BootCurrent: 0001
Timeout: 0 seconds
BootOrder: 0001,0000,0003,0007
Boot0000* Windows Boot Manager
Boot0001* ubuntu
Boot0003  Onboard NIC (IPV4)
Boot0007  Onboard NIC (IPV6)

In my case it is Windows 10 is Boot0000.

Using these instructions: How to delete boot managers from a UEFI boot menu, I would type:

efibootmgr -b 0000 -B
