ubuntu22.04.05 U盘全自动安装--镜像修改
工具准备
UltraISO
文件准备
UltraISO 工具打开 原始 iso文件
1. 修改文件 .\boot\grub\grub.cfg
set timeout=30
loadfont unicode
set menu_color_normal=white/black
set menu_color_highlight=black/light-gray
menuentry "Install Ubuntu22.04.05 Server" {
set gfxpayload=keep
linux /casper/vmlinuz quiet autoinstall ds=nocloud\;s=/cdrom/server/ ---
initrd /casper/initrd
}其中，“/cdrom”表示U盘根目录。
2.新建文件夹 .\server
3.在 server 下放入两个文件 meta-data，user-data，其中 meta-data 是一个空的文本文件
user-data的内容如下（基础版本可以通过手动安装一次后取得）
