[技术文章] Win7系统硬盘MBR分区无损转GPT分区方法

Dell Optiplex台式机换大硬盘,单分区大小超过2T需要转换MBR分区为GPT分区。
1、WinPE中:
(1)GiskGenuis,MBR分区转化为GPT分区(右击硬盘,转换分区表类型为GUID格式)。
(2)GiskGenuis,建立100M的ESP启动分区,用于存放EFI启动文件。
(3)所有程序→引导修复→UEFI引导修复→选创建的ESP分区及Windows系统根目录→开始修复,若ESP分区中无法写入文件,则点“命令提示符按钮”,输入如下命令:
  1. bcdboot D:\Windows /s C: /f uefi /l zh-cn
复制代码
其中:D为WinPE下Windows系统所显示的盘符,C为所创建的ESP启动分区所显示的盘符,回车后提示成功:
Boot files successfully created.

2、BIOS中:
(1)Settings→General→Boot sequence, Boot List Option中将启动方式由Legecy改为UEFI。
(2)Settings→Secure Boot→Secure Boot Enable改为Disabled,关闭安全启动,若不关闭安全启动则启动时会报以下错误:
Operating System Loader has no signature. Incompatible with SecureBoot.
Operating System Loader signature not found in SecureBoot database ('db').
(3)Settings→General→Advanced Boot Options,选中“Enable Legacy Option ROMs”,以UEFI兼容模式启动。
若不选中此项,则以纯UEFI模式启动(Win7不支持纯UEFI模式启动、Win8/Win10支持),会报错如下:
Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

File:  \EFI\Microsoft\Boot\BCD

Status: 0xc000000d

Info: an error occurred while attempting to read the boot configuration data.
