gpt add: disk0: error: no space available on device [duplicate]

Solution 1:

A bootable OS X partition (except the Recovery HD) either has the GUID 48465300-0000-11AA-AA11-00306543ECAC for a standard OS X partition, the GUID 53746F72-6167-11AA-AA11-00306543ECAC for a CoreStorage partition or the GUID 7C3457EF-0000-11AA-AA11-00306543ECAC for an APFS volume. The FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF is an unknown partition type (but not no partition like the 000000-0000-0000.... one).

The GUID can be modified with gpt. You can only add, delete and modify GUID partition tables with gpt when all related disks are unmounted. To reconfigure your partitions boot to a third party drive (e.g. Internet Recovery or a OS X installer thumb drive).

Under certain circumstances SIP has to be disabled to modify the GUID partition table.

Boot to Internet Recovery Mode (or a third party drive).
Open Terminal in the menubar Utilities > Terminal
Get an overview with diskutil list
Get an overview of your internal disk with the disk identifier found in the previous command. Below I assume the disk identifier of your internal disk is disk0 (SSD) (replace it with the one you have found in your environment).
```
  gpt -r show disk0
```
Unmount disk0 with diskutil umountDisk disk0
Then remove and re-add the second partition with the same size but proper type. The most probable type for disk0s2 on an SSD with Sierra currently installed is 53746F72-6167-11AA-AA11-00306543ECAC or with High Sierra installed 7C3457EF-0000-11AA-AA11-00306543ECAC (because a previous CoreStorage partition was almost certainly converted to APFS while upgrading Sierra to High Sierra).

Note: If any of the gpt add commands below generate the error message gpt add: disk0: error: no space available on device, then see this answer for a possible fix.

Sierra (CoreStorage):

    gpt remove -i 2 disk0
    gpt add -i 2 -b 409640 -s 431203056 -t 53746F72-6167-11AA-AA11-00306543ECAC disk0

High Sierra (APFS):

    gpt remove -i 2 disk0
    gpt add -i 2 -b 409640 -s 431203056 -t 7C3457EF-0000-11AA-AA11-00306543ECAC  disk0

standard partition (HFSJ Extended):

    gpt remove -i 2 disk0
    gpt add -i 2 -b 409640 -s 431203056 -t 48465300-0000-11AA-AA11-00306543ECAC  disk0

Verify disk and volume:

  diskutil verifyDisk disk0
  diskutil verifyVolume disk0s2

Booted to your USB drive and logged in as an admin you have to prepend sudo to execute the gpt commands successfully.

If you forgot your system version or did some custom partitioning you can still inspect the first blocks of disk0s2 and determine the proper GUID type:

If you've booted to a full-fledged system you can use hexdump:

Unmount disk0 with diskutil umountDisk disk0
hexdump the first 3 blocks of the FFFF... partition:
```
  sudo dd if=/dev/disk0s2 count=3 | hexdump
```

The following result identfies it as a normal OS X partition:

The first number is the byte count in hex: 0000000: 0; 0000600: 1536. The * denotes identical lines. This means: the first two blocks (0x000-0x3ff) are all zeros.

A CoreStorage partition shows some non-zeros in the first block (0x000-0x1ff):

The line starting with byte 0x130 shows the UUID of the Physical Volume, the line starting with byte 0x140 shows the UUID of the Logical Volume Group.

The string 48 46 53 4a (= "HFSJ") in the first 16 bytes of the third blocks identifies a Journaled HFS+ volume on both partition types.

An APFS container looks like this:

The string 4e 58 53 42 (= "NXSB") starting with byte 0x020 in the first block is the magic string of an APFS container superblock and identifies it as APFS container. The UUID of the container starts at 0x48 (here: 11 f1 5e 40 ...)

If you are limited to (Internet) Recovery Mode or an installer boot drive (all with a base system only which doesn't contain hexdump) you can still use vis:

Unmount disk0 with diskutil umountDisk disk0
vis the first 3 blocks of the FFFF... partition:
```
  dd if=/dev/disk0s2 count=3 | vis -c
```

If you had a standard partition previously the first 1024 Bytes only contain non-printable (zeros): \0\0\0\0\0\0... After ~Byte 1030 you will see the following sequence: \0HFSJ\0

If you had a CoreStorage partition some non-zeros in the first 512 Bytes and the string CS (...\0CS\^A...) are shown:
