服务器Windows一键重装为Linux (netboot,网络安装)

文章核心内容来自@萌咖大佬！

特别提醒：一键重装有一定的风险，请做好数据备份，准备好抢救方案！

有些厂商的机器因策略问题,不支持Windows重装为Linux. 例如: 腾讯云非大陆区域，有些厂商Windows系统盘会比Linux系统盘大,例如: AZURE，有些厂商不支持VNC,对于转换系统不方便，而这篇文章就可以解决以上问题！

使用前,请耐心看完文章，如果造成损失，小萌&萌咖大佬不负任何责任!

使用方法

1. 下载 win32loader.bat （分流下载：https://pan.baidu.com/s/1UyEn7B4OPa7jmqANzPYHdQ）.
2. 双击打开此文件.
3. 自行选择选项.
4. 按回车重启,并等待安装完成.

注意事项

默认提供的是Debian8(Jessie)，添加了firmware包,提供了更多的驱动支持,DHCP模式一键.

非DHCP模式,如果要一键,则需要自己定制镜像.

定制Debian系镜像应该没问题,其他未作测试.

默认root账户密码 Vicer .

如果厂商不支持VNC,则需要自己定制镜像.

定制方法参考：https://51.ruyo.net/5561.html

主要在镜像中添加机器的网络参数,以便支持一键安装.

命令示例:

bash InstallNET.sh -d 8 -v 64 -a --ip-addr <IP> --ip-mask <NetMask> --ip-gate <GATE> --loader

完成后将  initrd.img 和  vmlinuz 存放到能直链下载的位置.

如果厂商支持VNC,则可以直选全部选1 .

安装的时候,自己填 IP地址，子网掩码, 网关, DNS服务器
.
DNS服务器推荐填:  8.8.8.8

区分是否为DHCP模式

非DHCP模式: 如上图,显示了详细的IP地址.(选项为:使用下面的IP地址)

DHCP模式: 参考上图.(选项为:自动获得IP地址)
