远程安装ubuntu时，发现机器无法识别网卡驱动，需要替换iso里的网卡驱动文件。但是发现即使什么都不修改，生成的iso文件也是无法启动的。
我制作的iso命令如下：
首先，解压iso文件：
xorriso -osirrox on -indev ./ubuntu-16.04.3-server-amd64.iso -extract / ./test > /dev/null
然后，不改变测试目录的内容。使用以下命令创建一个 iso 文件。
mkisofs -allow-limited-size -r -iso-level 3 -joliet-long -D -r -V "ubuntu-16.04.3-server-amd64.iso" -cache-inodes -J -l -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o ./test.iso ./test
输出如下：
I: -input-charset not specified, using utf-8 (detected in locale settings)
Size of boot image is 4 sectors -> No emulation

ubuntu-16.04.3-server-amd64.iso从官网下载，可以正常安装，但是无法test.iso启动。
我查了很多资料，但没有发现任何有用的信息。
你能帮助我吗？或者还有其他命令可以制作可启动的 iso 文件吗？
