[已解决] 关于grub的iso引导以及copytoram

因为某些没有什么参考价值的奇怪的个人原因, 我可能需要通过grub直接引导ram中的livecd, 我在已经安装好arch的虚拟机里进行试验:
grub shell: 

set root=<mydisk> 
set isofile=<my-dir-to-iso>
loopback loop $isofile
linux (loop)/arch/boot/x86_64/vmlinuz-linux archisobasedir=arch archisolabel=ARCH_202212 toram				//from archlinux-2022.12.01-x86_64.iso/EFI/BOOT/grub.cfg
initrd (loop)/arch/boot/intel-ucode.img (loop)/arch/boot/amd-ucode.img (loop)/arch/boot/x86_64/initramfs-linux.img	//from archlinux-2022.12.01-x86_64.iso/EFI/BOOT/grub.cfg
boot

详见下图:

在 "boot" 之后, 直到 "Mounting" 之前, 都没有出现什么问题. (至少看起来是这样)

但是......

请问这是什么情况, 以及应该如何解决, 还是我的操作有什么问题?

虚拟机配置:

Re: [已解决] 关于grub的iso引导以及copytoram

grub 直接引导 iso 文件，给的参数不够。这是我的：

  linux (loop)/arch/boot/x86_64/vmlinuz-linux archisolabel=ARCH_202109 img_dev=/dev/sda7 img_loop=$isofile earlymodules=loop

感谢仙子, 已经成功.
