On my 2011 MacBook Pro, I've suddenly lost ability to EFI boot two separate Linux partitions. I can still boot via grub.

The two Linux distros on the same drive: Ubuntu and Deepin, both of which have booted just fine via EFI for many months.

Suddenly, they have BOTH stopped. I rarely boot into Deepin so there have been no recent updates. Ubuntu gets updated every couple days.

So I asked myself what to they share? Refind, the Mac's pram.

I reinstalled refind and used the default config. I zapped the pram... nothing seems to work. Any ideas?

UPDATE: Installed refind again and zapped the pram again and now it's ok. Weird.

Thanks.
