今日在安装系统时发现 连基本的windows 7都不会安装了，仔细研究了了下 才知道原因：

后来咨询研究了 才知道原因：

总结下：

NVMe ---连接 -- SSD 但是, SSD的接口可以是基于NVMe或是以前的SATA

NVMe -- 不支持 -- MBR

NVMe -- 支持 -- GPT

*g关于SSD的SATA和PCIE还有NVMe，请看文章 http://www.ithome.com/html/digi/262202.htm  *

UEFI （security boot）   ---- 对应 ---- GPT （GUID Partiations）

  I                                                            I

对应                                                  对应

  I                                                            I

BIOS （Basic INput Output）-对应----MBR （支持4个主分区，2TB限制）

Windows 7 系统本身，没有 NVMe Driver 和 USB 3.0 Driver

SkyLake 是 Intel 第六代的CPU，已经不支持USB2.0，支持USB3.0以上

*UEFI is intended to be used with the GPT partition type, but can be configured to use MBR on systems designed with Legacy BIOS support, but there are functional limitations and performance limitations associated with this legacy support.*

“Non-Volatile Memory express (NVMe) is a communications interface/protocol developed specially for Solid State Drives (SSD). Previously, Solid State drives used hard drive controller interfaces (SATA, SAS etc.) that were designed for spinning hard disk drives. NVMe (Based on the PCI Express data bus) standardizes the interface for SSDs requiring only 1 driver for all drives using this specification. (Similar to USB devices)”

所以当你拿到一台 Intel 6 代以上的SSD的笔记本需要按照windows 7时就要注意了，我们需要在windows 7 上封装至少下面两个驱动：

NVMe 和 USB 3.0 驱动

可以交接启动方式为UEFI，但是需要在你的启动USB中设置为这个方式
