2# 该脚本用于将disk_mount目录下的文件写入到disk-${ARCH}.img的第一个分区中，
3#       并在磁盘镜像中安装grub引导程序
4#
5# 用法：bash write_disk_image.sh --bios legacy/uefi
6# 如果之前创建的 disk-${ARCH}.img 是MBR分区表，那么请这样运行它：bash write_disk_image.sh --bios legacy
7# 如果之前创建的 disk-${ARCH}.img 是GPT分区表，那么请这样运行它：bash write_disk_image.sh --bios uefi
8# 通过设置ARCH为x86_64/i386/riscv64，进行64/32位uefi的install，但是请记住该处的ARCH应与run-qemu.sh中的一致
