Hi, I have an old Yosemite recovery partition that always stays on my Boot selection which screws up booting sometimes due to myself using Nvidia which doesn't have a boot screen.

I used the following command under Terminal below but both didn't work under High Sierra. Debug menu not showing.

defaults write com.apple.DiskUtility DUDebugMenuEnabled 1

When I do type diskutil list I do see the partition drive (disk3s3).

May I know why I'm not seeing this?

Thanks.

Look at Erasing Volumes section in the article below:

Thanks the command says:

diskutil eraseVolume JHFS+ New /Volumes/SecondVolume

Below is my partition I want to erase.

/dev/disk3 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *1.0 TB disk3
1: EFI EFI 209.7 MB disk3s1
2: Apple_HFS Macintosh HDD 999.3 GB disk3s2
3: Apple_Boot 650.0 MB disk3s3

What command should I put? I tried disk3s3 and so forth (diskutil eraseVolume JHFS+ New dev/disk3/Apple_Boot or diskutil eraseVolume JHFS+ New dev/disk3/disk3s3) but it says it cannot find the disk. Sorry for the noob question. Thanks in advance.
