Linux Install on Mac. Macos Asks to Initialize Install of Linux on Mac went fine, but I want to get rid of the initialize unreadable popup for the disk after macOS boots. Tried adding the UUIDs in the fstab file but it did not work.
Do I need the UUID of the disk itself? It's an 80 GB disk dedicated to Linux with 3 partition.
One 1 MB Bios Boot Partition, an EXT4 of 60 GB for Linux Filesystem and a Linux Swap of 15 GB.
I had added the UUIDs of the the three partition as that was all I could get of them.

Having switched the installations grub to EFI and having shrunk the EXT4 partition by 200 mb, creating a fat 32 partition and naming it EFI, the message does not show up anymore.
Additionally, the Nvidia driver works as well in EFI mode. I would not expect though that any of the non bios version drivers would work. 340 is the one marked &quot;bios&quot;.
