Bug Description
After upgrading to the new grub the boot menu only contains the memtest86 entries.
It can be easily reproduced by installing the system with ZFS (either plain ZFS or with encryption) using the latest desktop legacy image https:/
For people facing the same issue, you can boot your system manually from grub with this:
set root=(hd0,gptX)
linux /BOOT/ubuntu_
initrd /BOOT/ubuntu_
boot
