I had a perfectly working system with OS X Sierra, Windows 10 and Ubuntu 17.04 on three separate SSDs. I use Clover UEFI boot loader can get into any of the OS without problem.
The nightmare started when last week I let Ubuntu upgrade from 17.04 to 17.10. I didn't detach the OS X SSD when the upgrade was happening. After restart, I found grub took over and I can only boot to Windows but not OS X.
At first I thought it was just Ubuntu changing the boot disk order, so I went into my BIOS and change the boot order back to the OS X SSD as the first one. It didn't fix the problem. I was still booting into grub. Then I detached my Ubuntu SSD and Windows SSD. It went straight into grub rescue, and gave me "Unkown filesystem" error.
Then I created a Unibeast USB drive for Sierra in hope it can recognize my OS drive. I can boot into Clover with the USB drive, but in the diskutil I found my OS X SSD partition as marked as Linux!?
I don't understand how Ubuntu upgrade would wipe out a completely unrelated disk? Anybody ran into this problem? I am running out of clues now.
