Booting Ubuntu installed on SSD on both Windows and Mac
I've been struggling for a bit on this. I've installed Ubuntu on my external SSD with the following Partition:
- 200MB EFI boot partition
- 1GB ext2, mount to /boot
- Swap
- Ext4
I did the installation from my Windows machine and it works.
Now, I want to run Ubuntu on both my Mac and Windows, but I am struggling to get Ubuntu to load on the Mac. I installed reFind on my SSD. However, when I load Ubuntu I keep getting this:
"a start job is running for dev-disk-by x2duuid"
Any idea on how I can get past this?
Thanks for the help!

Did you copy /EFI/ubuntu from PC's internal drive to external SSD's ESP - efi system partition. You have to copy twice, once to /EFI/ubuntu & again to /EFI/Boot and rename shimx64.efi to bootx64.efi. That is because UEFI only boots from /EFI/Boot/bootx64.efi on external drives, but copy of shim or grub expects more files in /EFI/ubuntu. It probably only works on PC as you have installed grub to internal drive.
