Unable to start iso file through grub2 command line and iventoy

[Sirius2016]

grub命令行启动iso文件：

set iso_path="/minios.iso"
loopback iso_root $iso_path
linux (iso_root)/minios/boot/vmlinuz boot=minios iso-scan/filename=$iso_path
initrd (iso_root)/minios/boot/initrd.img
boot

具体报错截图：

我测试使用iventoy从网络pxe启动也是报上图一样的错误。

I tested using iventoy to boot from network PXE, but it also reported the same error as shown in the picture.

It seems that the .sb module file could not be loaded successfully.

好像是.sb模块文件无法加载成功。
