UEFI MBR GPT BIOS DELL SSD Windows 7

今日在安裝系統時發現 連基本的windows 7都不會安裝了，仔細研究了了下 才知道原因：

后來咨詢研究了 才知道原因：

總結下：

NVMe ---連接 -- 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關于SSD的SATA和PCIE還有NVMe，請看文章 http://www.ithome.com/html/digi/262202.htm  *

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

  I                                                            I

對應                                                  對應

  I                                                            I

BIOS （Basic INput Output）-對應----MBR （支持4個主分區，2TB限制）

Windows 7 系統本身，沒有 NVMe Driver 和 USB 3.0 Driver

SkyLake 是 Intel 第六代的CPU，已經不支持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)”

所以當你拿到一臺 Intel 6 代以上的SSD的筆記本需要按照windows 7時就要注意了，我們需要在windows 7 上封裝至少下面兩個驅動：

NVMe 和 USB 3.0 驅動

可以交接啟動方式為UEFI，但是需要在你的啟動USB中設置為這個方式
