Question 1: Configuration instructions CPU: Intel i7 7700 Graphics card: CPU integration Motherboard: ROG STRIX Z270E GAMING BIOS starts UEFI and secure boot (64Bit UEFI)
Shim15->Ubuntu Grub2(applied/ubuntu/bionic-devel) Booting to Ubuntu Grub2 stuck, the screen is always black, you can only restart the computer by pressing the restart button. If you turn off the safe boot, everything works fine. I can rule out that it is caused by shim15, because after I deleted the grub.efi file, shim15 prompts that grub.efi cannot be found. Finally, I deleted the grub.cfg file and it still stuck. The above problem is normal if you use the Fedora29 Grub2 code ( https://github.com/rhboot/grub2/tree/fedora-29). Question 2: The test platform is VMware14, and the BIOS has enabled UEFI and Secure Boot (32Bit UEFI). 32Bit UEFI will not have the above problem, but it will be stuck when bootloader is used to boot the bootmgfw.efi file of Windows system. This is the case with Ubuntu Grub2 (applied/ubuntu/bionic-devel) and Fedora29 Grub2 (https://github.com/rhboot/grub2/tree/fedora-29). Debian Grub2's 32Bit Grub2 ( https://salsa.debian.org/grub-team/grub/tree/debian/2.02+dfsg1-4) has no problems, but he will have the stuck condition described in question 1. I am not very familiar with the grub2 code, but I can assist with the test.
