使用 PowerShell 修改 Windows BCD
5.00/5 (6投票s)
在 PowerShell 中处理 Windows BCD 存储
背景
由于 BCD 的复杂性，本文将不会深入介绍 BCD。本文旨在演示管理 BCD 存储区的经过测试的技术。对于本文，所有 BCD 操作都在本地进行。此外，BCD 的 WMI 提供程序需要管理员权限。
警告
不当地修改系统 BCD 存储区可能导致操作系统无法启动。尽管本文的代码已将 bcd.mof 文件完全转换为 PowerShell 函数，但并非所有方法都会涵盖，本文未涵盖的方法也未经广泛测试。在使用本文未描述的方法之前，请查阅 Microsoft 文档。Microsoft 和作者对本代码的使用方式概不负责。
代码更新
为解决 COM 错误，增加了对 PowerShell 5 的支持。
访问 BCD 存储区
本文将使用 WbemScripting.SWbemLocator 对象来访问 BCD 提供程序。在并排比较中，使用 System.Management 命名空间的 C# 应用程序和使用 WbemScripting 的 PowerShell 脚本使用相同的资源：wmiprvse、wmiutils、wbemsvc、wbemcomn2、wbemprox、bcdprov 和 bcdsrv（以及其他）。对于 PowerShell，使用 WMI 脚本 API 更为容易。通过仅使用 COM 对象，只需几个（简单的）函数即可访问 BCD WMI 提供程序。
获取 static 类 BcdStore 的实例
function Get-StaticBcdStore {
$SWbemLocator = New-Object -ComObject WbemScripting.SWbemLocator
$wmi = $SWbemLocator.ConnectServer(".","root\wmi")
$wmi.Get("BcdStore")
}
四个 COM 辅助函数
访问方法参数
function New-InParameter {
Param([Parameter(Position=0)]$Method, [Parameter(ValueFromPipeLine=$true)]$Object)
$Object.Methods_.Item($Method).InParameters.SpawnInstance_()
}
访问属性
function Get-PropertyValue {
Param([Parameter(Position=0)]$Property, [Parameter(ValueFromPipeLine=$true)]$Object)
$Object.Properties_.Item($Property).Value
}
function Set-PropertyValue {
Param([Parameter(Position=0)]$Property, [Parameter(Position=1)]$Value,
[Parameter(ValueFromPipeLine=$true)]$Object)
$Object.Properties_.Item($Property).Value=$Value
}
方法执行和参数返回值
function Invoke-Method {
Param([Parameter(Position=0)]$Method, [Parameter(Position=1)]$ParameterNames,
[Parameter(Position=2)]$ParameterValues,
[Parameter(ValueFromPipeLine=$true)]$Object)
if($ParameterNames -eq $null -or $ParameterValues -eq $null) {
# If the method has required parameters: "The remote procedure call failed."
$Object.ExecMethod_($Method)
}
else {
$in = $Object.Methods_.Item($Method).InParameters.SpawnInstance_()
if($ParameterNames.GetType() -eq [System.String]) {
$prop = $in.Properties_.Item($ParameterNames)
$prop.GetType().InvokeMember("Value",
[System.Reflection.BindingFlags]::SetProperty,$null,$prop,@($ParameterValues))
}
else {
for($i = 0; $i -lt $ParameterNames.LongLength; $i++) {
if($ParameterValues[$i] -ne $null) {
$prop = $in.Properties_.Item($ParameterNames[$i])
if($ParameterValues[$i] -is [array]) {
$prop.GetType().InvokeMember("Value",
[System.Reflection.BindingFlags]::SetProperty,
$null,$prop,@(,$ParameterValues[$i]))
} else {
$prop.GetType().InvokeMember("Value",
[System.Reflection.BindingFlags]::SetProperty,
$null,$prop,@($ParameterValues[$i]))
}
}
}
}
$Object.ExecMethod_($Method, $in)
}
}
实现 BCD WMI 方法
BCD 提供程序公开的所有方法都可以在 bcd.mof（Managed Object Format）文件中找到。对于本文，以及提供的 PowerShell 代码，它们根据对象关系分为三个主要类别：仅与
BcdStore 相关的函数和属性、仅与 BcdObject 相关的函数和属性，以及与 BcdElements 相关且包含共享属性的函数和属性。在实现这些方法时，任何 out 参数都用作函数的返回值，否则，返回值将是一个布尔值，指示操作的成功或失败。处理 BCD 存储区
要访问存储区并检索项目，将使用以下方法
function Open-Store {
Param(
[Parameter(Position=0)][string]$File="",
[Parameter(Mandatory=$true, ValueFromPipeLine=$true)]$BcdStore
)
$BcdStore | Invoke-Method "OpenStore" "File" $File | Get-PropertyValue "Store"
}
function Open-Object {
Param(
[Parameter(Position=0)][string]$Id,
[Parameter(Mandatory=$true, ValueFromPipeLine=$true)]$BcdStore
)
$BcdStore | Invoke-Method "OpenObject" "Id" $Id | Get-PropertyValue "Object"
}
function Enumerate-Objects {
Param(
[Parameter(Position=0)][uint32]$Type,
[Parameter(Mandatory=$true, ValueFromPipeLine=$true)]$BcdStore
)
$BcdStore | Invoke-Method "EnumerateObjects" "Type" $Type | Get-PropertyValue "Objects"
}
要打开 BCD 存储区，必须指定 BCD 文件名。空字符串表示系统存储区。获取 BCD 对象需要对象的 GUID 标识。枚举 BCD 对象需要一个对象类型。
$bootmanager = Get-StaticBcdStore | Open-Store -file "" |
Open-Object "{9dea862c-5cdd-4e70-acc1-f32b344d4795}"
$bootmanager.Properties_
在此示例中，使用 Windows 引导管理器（Windows Boot Manager）的已知 GUID 从系统存储区获取引导管理器，并输出 COM 属性。结果仅为 BcdObject 属性：Id（即已知 GUID）、StoreFilePath（因为在系统存储区中，所以为空）和 Type（即 0x10100002）。
在上一个示例中，通过使用已知 GUID 显式检索了引导管理器。但是；也可以通过其类型来检索此元素。
$bootmanagers = Get-StaticBcdStore | Open-Store "" |
Enumerate-Objects ([uint32]"0x10100002")
$bootmanagers[0].Properties_
或
$bootmanagers = Get-StaticBcdStore | Open-Store "" | Enumerate-Objects ([uint32]"0x10000002")
$bootmanagers[0].Properties_
这些示例指出了按类型定义枚举对象的能力。在第二个示例中，对象类型被泛化，以指示任何应用程序代码为 Windows 引导管理器的应用程序类型对象。
要创建 BCD 存储区和 BCD 对象，将使用以下两个方法
function Create-Store {
Param(
[Parameter(Position=0)][string]$File,
[Parameter(Mandatory=$true, ValueFromPipeLine=$true)]$BcdStore
)
$BcdStore | Invoke-Method "CreateStore"
"File" $File | Get-PropertyValue "Store"
}
function Create-Object {
Param(
[Parameter(Position=0)][uint32]$Type,
[Parameter(Position=1)][string]$Id,
[Parameter(Mandatory=$true, ValueFromPipeLine=$true)]$BcdStore
)
$BcdStore | Invoke-Method "CreateObject"
"Id","Type" $Id,$Type | Get-PropertyValue "Object"
}
与 OpenStore 方法类似，BcdStore 的 CreateStore 方法需要一个文件名。在 BCD 存储区中创建对象需要一个类型和一个可选的 GUID 或已知 GUID。
Get-StaticBcdStore | Create-Store "$env:TEMP\BCD-Demo" `
| Create-Object ([uint32]"0x10100001")
"{a5a30fa2-3d06-4e9f-b5f4-a01df9d1fcba}"
在此示例中，使用固件引导管理器（Firmware Boot Manager）的已知 GUID 和固件引导管理器（Firmware Boot Manager）的对象类型来创建：固件引导管理器。Id 参数是可选的。要创建新对象，只需传递对象类型，对象的 Id 将由提供程序生成的 GUID 填充。但是，许多对象，如这个固件引导管理器，只能通过已知的 GUID 和类型组合来创建。
处理 BCD 对象
设置元素需要 BcdObject 提供的。这些方法共有的特点是使用 Type 来定义要操作的对象元素。Microsoft 的 MSDN 提供了相当完整的（尽管不总是准确的）枚举列表。我的意思是，一些枚举值可能被定义为特定类型，但它们实际上不是该类型，而其他缺失的枚举值——尽管它们可以用现有值替代。
以下方法用于从 BcdObject 中检索元素数据
function Enumerate-Elements {
Param([Parameter(Position=0, ValueFromPipeLine=$true)]$BcdObject)
$BcdObject | Invoke-Method "EnumerateElements" | Get-PropertyValue "Elements"
}
function Get-Element {
Param([Parameter(Position=0)][uint32]$Type,
[Parameter(ValueFromPipeLine=$true)]$BcdObject
)
$BcdObject | Invoke-Method "GetElement"
"Type" $Type | Get-PropertyValue "Element"
}
function Enumerate-ElementTypes {
Param([Parameter(Position=0, ValueFromPipeLine=$true)]$BcdObject)
$BcdObject | Invoke-Method "EnumerateElementTypes" | Get-PropertyValue "Types"
}
要获取元素、元素类型和值的列表，只需执行以下操作
$bootmanager = Get-StaticBcdStore | Open-Store -file "" |
Open-Object "{9dea862c-5cdd-4e70-acc1-f32b344d4795}"
$bootmanager | Enumerate-ElementTypes | % {
(Get-Element -Type $_ -BcdObject $bootmanager).Properties_
}
至于设置元素数据，以下方法将在后面演示，但名称如 SetBooleanElement 和 SetStringElement，它们不言自明。
function Set-StringElement {
Param(
[Parameter(Position=0)][uint32]$Type,
[Parameter(Position=1)][string]$String,
[Parameter(ValueFromPipeLine=$true)]$BcdObject
)
$BcdObject | Invoke-Method "SetStringElement"
"Type","String" $Type,$String | Get-PropertyValue "ReturnValue"
}
function Set-BooleanElement {
Param(
[Parameter(Position=0)][uint32]$Type,
[Parameter(Position=1)][bool]$Boolean,
[Parameter(ValueFromPipeLine=$true)]$BcdObject
)
$BcdObject | Invoke-Method "SetBooleanElement"
"Type","Boolean" $Type,$Boolean | Get-PropertyValue "ReturnValue"
}
function Set-IntegerElement {
Param(
[Parameter(Position=0)][uint32]$Type,
[Parameter(Position=1)]$Integer,
[Parameter(ValueFromPipeLine=$true)]$BcdObject
)
$BcdObject | Invoke-Method "SetIntegerElement"
"Type","Integer" $Type,$Integer | Get-PropertyValue "ReturnValue"
}
function Set-ObjectElement {
Param(
[Parameter(Position=0)][uint32]$Type,
[Parameter(Position=1)][string]$Id,
[Parameter(ValueFromPipeLine=$true)]$BcdObject
)
$BcdObject | Invoke-Method "SetObjectElement"
"Type","Id" $Type,$Id | Get-PropertyValue "ReturnValue"
}
一些方法将接受值数组，应使用 @() 传递这些值。
function Set-ObjectListElement {
Param(
[Parameter(Position=0)][uint32]$Type,
[Parameter(Position=1)]$Ids,
[Parameter(ValueFromPipeLine=$true)]$BcdObject
)
$BcdObject | Invoke-Method "SetObjectListElement"
"Type","Ids" $Type,$Ids | Get-PropertyValue "ReturnValue"
}
function Set-IntegerListElement {
Param(
[Parameter(Position=0)][uint32]$Type,
[Parameter(Position=1)]$Integers,
[Parameter(ValueFromPipeLine=$true)]$BcdObject
)
$BcdObject | Invoke-Method "SetIntegerListElement"
"Type","Integers" $Type,$Integers | Get-PropertyValue "ReturnValue"
}
设置设备数据要复杂得多，也将在后面演示
function Set-FileDeviceElement {
Param(
[Parameter(Position=0)][uint32]$Type,
[Parameter(Position=1)][int]$DeviceType,
[Parameter(Position=2)][string]$AdditionalOptions,
[Parameter(Position=3)][string]$Path,
[Parameter(Position=4)][uint32]$ParentDeviceType,
[Parameter(Position=5)][string]$ParentAdditionalOptions,
[Parameter(Position=6)][string]$ParentPath,
[Parameter(ValueFromPipeLine=$true)]$BcdObject
)
$parameterNames = "Type","DeviceType","AdditionalOptions",
"Path","ParentDeviceType","ParentAdditionalOptions","ParentPath"
$parameterValues = $Type,$DeviceType,$AdditionalOptions,
$Path,$ParentDeviceType,$ParentAdditionalOptions,$ParentPath
$BcdObject | Invoke-Method "SetFileDeviceElement"
$parameterNames $parameterValues | Get-PropertyValue "ReturnValue"
}
function Set-PartitionDeviceElement {
Param(
[Parameter(Position=0)][uint32]$Type,
[Parameter(Position=1)][int]$DeviceType,
[Parameter(Position=2)][string]$AdditionalOptions,
[Parameter(Position=3)][string]$Path,
[Parameter(ValueFromPipeLine=$true)]$BcdObject
)
$parameterNames = "Type","DeviceType",
"AdditionalOptions","Path"
$parameterValues = $Type,$DeviceType,$AdditionalOptions,$Path
$BcdObject | Invoke-Method "SetPartitionDeviceElement"
$parameterNames $parameterValues | Get-PropertyValue "ReturnValue"
}
BcdObject 提供了更多方法，并在本文后面的代码中包含，尽管本文未涵盖。
处理 BCD 元素
最后一个介绍 BCD 方法的部分将介绍 BCD 对象的实际元素。在前面的部分中，我们介绍了如何使用 BcdStore 对象来打开和创建对象，并简要提及了如何使用 BcdObject 来设置元素数据。要从元素中获取特定信息，我们必须访问元素的属性。string 元素有一个 String 属性，布尔元素有一个 Boolean 属性，依此类推。
function Get-String {
Param([Parameter(Mandatory=$true, Position=0, ValueFromPipeLine=$true)]$BcdStringElement)
Get-PropertyValue "String" -Object $BcdStringElement
}
function Get-Integer {
Param([Parameter(Mandatory=$true, Position=0, ValueFromPipeLine=$true)]$BcdIntegerElement)
Get-PropertyValue "Integer" -Object $BcdIntegerElement
}
function Get-Boolean {
Param([Parameter(Mandatory=$true, Position=0, ValueFromPipeLine=$true)]$BcdBooleanElement)
Get-PropertyValue "Boolean" -Object $BcdBooleanElement
}
对于对象列表
function Get-Integers {
Param([Parameter(Mandatory=$true, Position=0, ValueFromPipeLine=$true)]$BcdIntegerListElement)
Get-PropertyValue "Integers" -Object $BcdIntegerListElement
}
function Get-Ids {
Param([Parameter(Mandatory=$true, Position=0, ValueFromPipeLine=$true)]$BcdObjectListElement)
Get-PropertyValue "Ids" -Object $BcdObjectListElement
}
对于设备对象
function Get-Device {
Param([Parameter(Mandatory=$true, Position=0, ValueFromPipeLine=$true)]$BcdDeviceElement)
$BcdDeviceElement | Get-PropertyValue "Device"
}
这将是获取 BCD 存储区数据的最后一个演示。（压轴好戏：获取设备数据。）
$mem = Get-StaticBcdStore | Open-Store "" |
Open-Object "{b2721d73-1db4-4c62-bf78-c548a880142d}"
$dev = $mem | Get-Element
-Type ([BcdLibraryElementTypes]::Device_ApplicationDevice) | Get-Device
$dev.Properties_
此示例获取 Windows 内存测试程序（Windows Memory Tester）并检索设备数据。此方法对于通过代码评估设置各种设备元素的属性非常有用。
最后，重头戏
现在…本文的最终目标是提供从 PowerShell 修改 BCD 存储区的实际示例。
从头开始构建 BCD 存储区
对于第一个演示，将使用实时系统存储区的 bcdedit 输出在代码中生成新的 BCD 存储区。生成的 BCD 存储区将创建一个已清理、重新格式化并在部署场景中重新映像的驱动器上。bcdedit 的大部分输出已按对象依赖关系重新排序。枚举器和已知 GUID 变量在本文末尾的代码中提供。
. ("$PSScriptRoot\PowershellBcd.ps1")
Get-StaticBcdStore | Create-Store -File "$env:TEMP\BCD-TEMP" | Out-Null
$bcdFile = "S:\boot\BCD"
if(Test-Path $bcdFile) {
Remove-Item -Path $bcdFile | Out-Null
}
$sDrive = Get-DosDevice "S:"
# Windows OS (will be C after reboot)
$cDrive = Get-DosDevice "W:"
$BcdStore = Get-StaticBcdStore | Create-Store -File $bcdFile
$BcdStore | Import-Store "$env:TEMP\BCD-TEMP" | Out-Null
*BCD WMI 提供程序似乎没有实现 QueryDosDevice——与 bcdedit 不同，在设置 Device 属性时，它不接受卷标。此外，虽然从头开始构建 BCD 存储区会生成一个功能齐全的存储区，并且操作系统能够正常启动、休眠和恢复，但启动到 WinRE 总是会导致 BCD 存储区重建。要使存储区正常工作，必须导入一个“虚拟”存储区。这会生成一个功能正常的 BCD 存储区。（此解决方案可在此链接找到。）

更新 USB BCD 存储区
对于第二个演示，将一个 WinPE 文件添加到现有的 WinPE USB 中。除了添加 Windows 引导加载程序外，还有必要更新 ems（紧急管理服务）设置以显示启动菜单（如果尚未启用）。由于 BCD 存储区已有一个 Ramdisk Option，因此不需要新的；但是，有必要获取现有 Device Option 的 Id。最后，在添加新的引导加载程序后，需要更新 Windows 引导管理器的显示顺序以包含新的引导加载程序。

仅为好玩——构建 BCD 模板
最后一个演示将重新创建位于 system32\config 的 BCD-Template。这将展示一些标准 BCD 存储区中未定义的 BCD 对象。
一些重复的操作已简化——例如，使用 Set-InheritedObjects 函数来包装 Set-ObjectListElement ([BcdLibraryElementTypes]::ObjectList_InheritedObjects)。此外，混合使用基本和详细的 bcdedit 输出，以提供更准确的演示代码结果。

看起来 BCD 提供程序乐于接受为引导加载程序等对象提供的 GUID，尽管如果允许，它也会生成这些 GUID。看起来 "{" + [guid]::NewGuid() + "}" 可以作为替代。尽管在测试中没有发现不良影响：强烈建议使用 BCD 提供的 GUID。
Microsoft 文档可在此链接找到。
BCD 示例可在 Windows SDK 7.1：BootConfigurationData 示例，Windows Vista AIK：SetAutoFailover.cmd，以及Hey Scripting Guy! 中找到。
如前所述，BCD 的细节很少。我发现学习 BCD 的最佳方法是检查 BCD 文件。使用 COM 的一大好处是可以迭代 Properties_，而无需预先知道 Id 或 Type。
额外说明：此代码最初是为 PowerShell 4.0 编写的，为 PowerShell 5 所需的代码更改。
