I have a situation very similar to the ones depicted in two previous questions I found ([this][1] and [this][2]), but still different (I address why my situation is different later on in the question). **The problem** I am really panicking, my computer has been in unbootable status for two days now and because of coronavirus lockdown, in Italy there is no any opened tech shop, at this point I do not know what to do and any help is very much appreciated. I had a ~50 GB linux partition on the SSD (total ~250 GB) of my 15” Macbook Pro mid-2015. I created this partition to boot ubuntu back in 2016 and I used it regularly alongside macOS. About one year ago I updated to Mojave 10.14, and this is the macOS version my computer is running now (I am mentioning it because I suppose that the update changed the file system of my macOS partition to APFS, keeping unmodified the ubuntu partition, I guess). Today I decided to remove the ubuntu partition, I started the computer on macOS, opened Disk Utility, find the ~50 GB partition assigned to ubuntu on the pie chart, I clicked on the “-“ sign to remove the partition and then “Apply”. Disk Utility returned to me instantly with an error (not remember exactly the text, but I remember that no error code was given) saying it could not perform the operation, so I googled a bit some solutions (MY COMPUTER WAS PERFECTLY WORKING) and I found a post suggesting to perform some operations from ubuntu, so I decided to restart my computer in order to open ubuntu - I repeat, it was perfectly working, many apps opened and fully working, etc. - and... It booted into “GNU GRUB version 2.02” I tried to restart my mac keeping “option” pressed, but it could only find the “EFI Boot” disk (picture attached) which is the one I usually select to boot Ubuntu. Also, Ubuntu now doesn’t even work anymore, because if I select “EFI Boot” it starts “GNU GRUB version 2.02”. Now I really started panicking, I don’t care about data of the ~50 GB ubuntu partition, but so foolishly I haven’t backed up the ~200 GB macOS data, and I am just so affectionate to them, I would really like to recover them. **Data Recap** - 15” Macbook Pro mid-2015 - Right now I am booting from the network. - 256 GB SSD partitioned in: - ~200 GB APFS macOS partition - FileVault encrypted - running Mojave 10.14 - ~50 GB ubuntu partition - don’t remember the file system (data here doesm’t matter to me) **Photos Attached** - `diskutil list` - `gpt -r show /dev/disk1` - disk1 information from Disk Utility - Disk Utility overview of the physical disk - booting situation with only the “EFI Boot” partition **Why is a different situation** My situation is different because of 3 reasons: - The ~50 GB ubuntu partition is disappeared, maybe corrupted, indeed if you add up all the disk's size in `diskutil list`, you still miss ~50 GB. - I have 2 disks at the same time (index 2 and index 3) that are in the FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF status - When I call `gpt -r show /dev/disk1` I don't get any *"Suspicious MBR at sector 0"* message unlike others users that wrote other questions. **Update 1** I just wanted to confirm that I am booting the mac from Network Recovery and also my Disk Utility version. Disku Utility Version is: "Version 13 (606)" - "Copyright 2002-2014 Apple Inc.". Is seems, indeed, pretty old [![Disk Utility overview of the physical disk][3]][3] [![diskutil list][4]][4] [![gpt -r show /dev/disk1][5]][5] [![booting situation with only the “EFI Boot” partition][6]][6] [![disk1 information from Disk Utility][7]][7] [![Disk Utility overview of the disk1s2][8]][8] [1]: https://apple.stackexchange.com/questions/307780/macos-partition-startup-volume-type-ffffffff-ffff-ffff-ffff-ffffffffffff [2]: https://apple.stackexchange.com/questions/238012/os-volume-shows-as-type-ffffffff-ffff-ffff-ffff-ffffffff-after-attempting-to-d# [3]: https://i.sstatic.net/HiG6L.jpg [4]: https://i.sstatic.net/GzQbB.jpg [5]: https://i.sstatic.net/pF3YE.jpg [6]: https://i.sstatic.net/9HkVC.jpg [7]: https://i.sstatic.net/A88Lu.jpg [8]: https://i.sstatic.net/BjT4t.jpg
