Is Macintosh-data partition deletable/undeletable..?

Why every time I try to make an Installation of MacOs Catalina it happens to appear the Macintosh-data partition to be there after the installation and if I try to go back to the recovery model and delete the Macintosh-data partition the system wont boot..?

If you correctly install the macOS you would expect to see Macintosh HD and Macintosh HD - Data.


From the Terminal you can see the drive structure here:

diskutil list internal



for example only—Catalina


MacBook-Pro ~ % diskutil list internal

/dev/disk0 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *1.0 TB disk0

1: EFI EFI 314.6 MB disk0s1

2: Apple_APFS Container disk1 1.0 TB disk0s2


/dev/disk1 (synthesized):

#: TYPE NAME SIZE IDENTIFIER

0: APFS Container Scheme - +1.0 TB disk1

Physical Store disk0s2

1: APFS Volume Macintosh HD 11.2 GB disk1s1

2: APFS Volume Macintosh HD - Data 273.7 GB disk1s2

3: APFS Volume Preboot 80.8 MB disk1s3

4: APFS Volume Recovery 529.0 MB disk1s4

5: APFS Volume VM 3.2 GB disk1s5





Under the the new APFS all Volumes share space within the Container without penalty.
