启动错误效果

 解决方案：重新下载grub源码，在ARM64银河麒麟桌面系统V10SP1上自行编译安装，再制作一个启动ISO镜像。

1. 下载源码

https://ftp.gnu.org/gnu/grub/grub-2.06.tar.xz

2. 编译安装

./configure --prefix=/usr/local --with-platform=efi
make
sudo make install

3. 生成启动ISO镜像

sudo apt install mtools xorriso -y
/usr/local/bin/grub-mkrescue -o ~/grub-arm64-efi.iso

xorriso 1.5.2 : RockRidge filesystem manipulator, libburnia project.

Drive current: -outdev 'stdio:/home/yeqiang/grub-arm64-efi.iso'
Media current: stdio file, overwriteable
Media status : is blank
Media summary: 0 sessions, 0 data blocks, 0 data,  281g free
Added to ISO image: directory '/'='/tmp/grub.5un3Nt'
xorriso : UPDATE :     274 files added in 1 seconds
xorriso : UPDATE :     274 files added in 1 seconds
ISO image produced: 5299 sectors
Written to medium : 5299 sectors at LBA 0
Writing to 'stdio:/home/yeqiang/grub-arm64-efi.iso' completed successfully.

4. 制作U盘启动版，这里直接采用Ventoy方案

(GitHub - ventoy/Ventoy: A new bootable USB solution.)

5. 重新引导启动，效果如下：

 搞定。
