我正在尝试设置多重引导 ISO USB 驱动器，但在启动 ISO 文件时收到错误消息。
据我所知，环回设备已正确执行，否则将无法启动 iso。然而，找不到正确的路径。
我不懂为什么。
也许循环设备需要更多选项，或者 GUBB2 需要一些模块。
1.“KDE neon GNU/Linux (.iso)”启动没有任何问题。
2. “Arch Linux (.iso)”给出以下错误消息：
启动命令列表
错误：没有这样的模块。
按任意键继续…
按 Enter 键后会发生以下情况
正在等待启动设备...
等待设备 /dev/disk/by-label/ARCH_202211 30 秒...
错误：'/dev/disk/by-label/ARCH_202211' 设备在 30 秒后未显示。回到
交互式提示。
3.“Windows 10 (.iso)”找不到该文件。
启动命令列表
错误：没有这样的模块。
错误：找不到文件“/efi/boot/bootx64.efi”
按任意键继续...
如果我解压 iso 并将其直接复制到分区上，则使用此命令 (grub.cfg) 时 Windows 启动不会出现问题：
search.fs_uuid 2222-UUID-2222 root hd0,gpt1
set prefix=($root)'/grub'
configfile $prefix/grub.cfg
menuentry 'Windows 10' {
chainloader (${root})/efi/boot/bootx64.efi
}
