[SOLVED] E7440 Mojave partitioning problem

Recommended Posts

I want to ask for help.
On E7440 I wanted to create a plus FAT partition under Mojave by reducing the existing one, as shown in the attached image for Linux.
Unfortunately, the partitioning process is interrupted by error code 49187.
Someone might have a tip on how I could solve this problem?
Thank you in advance for your answers!

I managed to solve the problem.
Error code 49187 appears to be an internal error in the structure of the APFS that occurred during the file system installation.
I couldn't find a solution to fix it, so I could only recover the following steps:
Step 1: I made a Time Machine backup (otherwise I just updated my existing one)
Step 2: I restarted the computer and selected the installation option from the USB installer
Step 3: I then run the following command in the terminal to list the disks:

Step 4: I selected the disk on which the macOS is installed (in this case, this was "disk1")
Step 5: Then I ran the following command (To convert an APFS container into a free space, you must first delete the container):

diskut about deleteContainer disk1

Step 6: Then restore the system using Time Machine

After restoring the system, I was able to partition without problems

When you erase the drive as GPT/HFS Partition under disk utility, for some reason it automatically creates a 100mb/200MB efi partition.


You need to do nothing else except mount it in Clover configurator or install clover on that drive.


You do not need to do any more partitioning. If you do, I would first go to windows / linux and make the partitions in the rgiht tools, and then use disk utility to format needed partitions to apple format.


OTHERWISE i have accidently erased partitions and lost data when relying on Disk Utility.
