I've split my 2TB HDD + 128GB SDD Fusion Drive into two separate disks so I can make better use of it by taking control on what is stored where. The process was fairly simple so I ended up with macOS installed on "SSD" and "HDD" for other storage.
This is how it looks now:
$ diskutil list /dev/disk0 (internal): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme 121.3 GB disk0 1: EFI EFI 314.6 MB disk0s1 2: Apple_APFS Container disk2 121.0 GB disk0s2 /dev/disk1 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *2.0 TB disk1 1: EFI EFI 209.7 MB disk1s1 2: Apple_HFS HDD 2.0 TB disk1s2 /dev/disk2 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +121.0 GB disk2 Physical Store disk0s2 1: APFS Volume SSD 70.1 GB disk2s1 2: APFS Volume Preboot 45.3 MB disk2s2 3: APFS Volume Recovery 510.3 MB disk2s3 4: APFS Volume VM 4.3 GB disk2s4
Is it normal to have EFI partitions on both drives? Or could it be just one? If so – which one macOS is using for boot?
Why I ended up in here? I wanted to make use of Boot Camp and install Win10 on "HDD".
But when I select
disk1 as target in Boot Camp, I get this message:
This disk contains Windows partition.
And three options to choose from:
- Create second partition for Windows.
- Erase disk and create single partition for Windows.
- Restore single macOS partition.
All would be just fine to select option #1, but... it is grayed out and disabled.
disk1s2 partition is type of Mac OS Extended (journaled). I'm assuming that Boot Camp says "...disk already contains Windows partition" because it has EFI?
Is there any way to use Boot Camp in this situation? Erasing "HDD" partition is not an option.
PS I can create another FAT32 partition by splitting "HDD" partition in Disk Util. But this changes nothing in context of Boot Camp.
