无法从 GRUB 2 启动 ISO

我在启动时遇到问题深入从 USB 中下载带有 GRUB 2 的 ISO 映像。我已经尝试修复这个问题将近一个星期了。以下是grub配置文件文件：

# GLEE USB GRUB2 Configuration

# Required with MBR for GUI
if [ "${grub_platform}" = "pc" ]; then
    insmod vbe
fi

# Required with EFI for GUI and to prevent "No video mode set" error
if [ "${grub_platform}" = "efi" ]; then
    insmod efi_gop
fi

# Keep the same graphic mode for kernel booting (passed as vga=)
# other values are "text" or any gfxmode value
set gfxpayload=keep

# Enable GUI
#GRUB_FONT=/boot/grub/fonts/unicode.pf2
if loadfont /boot/grub/fonts/unicode.pf2 ; then
    insmod gfxterm
    terminal_output gfxterm
fi

# EFI: special characters (lines composing menu frame)
# replaced by '?' in text _fallback_ text mode if absent
# (useless if gfxterm is not enabled or if GUI theme loading success)
#loadfont ascii

insmod png
set theme=${prefix}/themes/Vimix_+_Atomic/theme.txt

set isopath=/boot/iso
# Required to have these available in other configfile files
export theme
export isopath

    }
fi

menuentry "Shutdown" --class shutdown {
  halt
}

menuentry "Restart" --class restart {
  reboot
}

现在我尝试启动的ISO镜像是“Deepin”，菜单项是：

if [ -e ${isopath}/deepin ]; then
menuentry "Deepin >" --class deepin {
  configfile "${prefix}/inc-deepin.cfg"
}
fi

这是配置文件inc-deepin.cfg：

# Deepin
if cpuid -l; then
menuentry "Deepin Live 15.5 amd64" --class deepin {
    set isoname="deepin-15.5-amd64.iso"
    set isofile="${isopath}/deepin/${isoname}"
    echo "Using ${isoname}..."
    loopback loop $isofile
    linux (loop)/live/vmlinuz boot=live iso-scan/ask_second_pass=true findiso=${isofile}
    initrd (loop)/live/initrd.lz
}

这个设置适用于 Ubuntu 的 GRUB 2（已测试 3-4 次），它是 Ubuntu 自带的默认引导程序（我用它来测试问题是否出在脚本本身（通过将菜单项（Deepin）添加到目录中的 40_custom 文件中）/etc/grub.d。

当使用上述设置通过 USB 启动时，会出现以下错误：

error: out of memory
error: syntax error
error: Incorrect command
error: syntax error

尝试使用 memdisk 启动时也会出现此错误。我该如何修复此问题？

我目前的想法是……

  1. 问题可能与大小或 RAM 无关。因为此设置在使用 Ubuntu 的 GRUB 进行测试时有效，但在使用 USB 启动 ISO 映像时失败。

  2. 由于 Deepin OS 基于Debian，我假设启动配置文件和Debian相同。

  3. 我在将 GRUB 安装到 USB 时使用了以下命令：

    GRUB_TARGET="--target=x86_64-efi --efi-directory=${MOUNT_POINT}
--removable"

GRUB2_INSTALL="grub2-install"

MOUNT_POINT=/media/microsoft10/MMI

PARTITION=/dev/sdb1

sudo ${GRUB2_INSTALL} ${GRUB_TARGET}
--boot-directory=${MOUNT_POINT}/boot ${PARTITION}
