为什么我可以从 MS MDT 服务器启动并安装 Windows，并使用 ISC 作为 dhcp 服务器，但只能在旧式 bios 下进行，而不是在 UEFI 下？

设置如下：

运行 ISC dhcp 客户端的 Windows 2012 R2 与 MDT 2013 Ubuntu Server 14.04.2 可以是 VM/硬件，无所谓。

如果我保持传统 BIOS 模式，一切就都运行良好。当我切换到 UEFI 并查看 DHCP 服务器上的日志时，我看到了 DCHPDISCOVE 和 DHCPOFFER，但没有 ACK。客户端永远不会接受该提议，也不会获得 IP。

我在 Google 上尝试过很多个选项，但都没有成功。

/etc/dhcp/dhcpd.con 非常基础。我有一个子网和一个范围集，以及路由器和 DNS。

这是我的 DHCPd 配置文件，希望它能为您的问题提供信息，因为我的设置正在运行。出于隐私原因，我已删除了我的 MAC 地址。如果您的设置与我的类似，那么您可能遇到了客户端问题...

# Sample configuration file for ISC dhcpd for Debian

# Attention: If /etc/ltsp/dhcpd.conf exists, that will be used as
# configuration file instead of this file.

#

# The ddns-updates-style parameter controls whether or not the server will
# attempt to do a DNS update when a lease is confirmed. We default to the
# behavior of the version 2 packages ('none', since DHCP v2 didn't
# have support for DDNS.)
ddns-update-style none;

# option definitions common to all supported networks...

# If this DHCP server is the official DHCP server for the local
