I've had this happen too, but I think it just changed something in the efivars, grub itself was still there and still operational, even though it didn't show up in the available boot options.
The workaround for me was the "boot from file" boot option, where I would be able to walk the directories in the efi partition and start grub. Once this was done, it was back in the boot option list.
- franga2000 6y agoYeah, I've only had it remove the actual files once, when I had to use the recovery USB thing to fix a broken update. Unfortunately, my motherboard is from the very early days of UEFI and doesn't allow me to select files or even manage keys so I have to keep a microSD card with a bunch of bootloaders handy in case this happens (I still haven't gotten around to learning UEFI shell in order to manually boot).
