# First Boot

During First Boot (Specialize Phase), any EXE based DriverPacks in C:\Drivers will be expanded.  Once expanded, they will be applied using the following PowerShell commands

```powershell
New-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths" -Name 1 -Force
New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths\1" -Name Path -Value $DestinationPath -Force
pnpunattend.exe AuditSystem /L
Remove-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths\1" -Recurse -Force
```

You can identify this phase by the "Getting ready"

## Dell Systems

Dell uses CAB files or EXE files that can be expanded in WinPE, so there is no activity in First Boot other than a long delay.  You can review the logs in C:\Windows\debug

```powershell
Start-Process -FilePath $ExpandFile -ArgumentList "/s /e=`"$DestinationPath`"" -Wait

Write-Verbose -Verbose "$((Get-Date).ToString('yyyy-MM-dd-HHmmss')) Applying DriverPack with PNPUNATTEND"
New-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths" -Name 1 -Force
New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths\1" -Name Path -Value $DestinationPath -Force
pnpunattend.exe AuditSystem /L
Remove-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths\1" -Recurse -Force
```

## HP Devices

HP DriverPacks are silent, so there is no progress displayed during this phase other than a long delay.  You can review the logs in C:\Windows\debug

```powershell
Start-Process -FilePath $ExpandFile -ArgumentList "/s /e /f `"$DestinationPath`"" -Wait

Write-Verbose -Verbose "$((Get-Date).ToString('yyyy-MM-dd-HHmmss')) Applying DriverPack with PNPUNATTEND"
New-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths" -Name 1 -Force
New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths\1" -Name Path -Value $DestinationPath -Force
pnpunattend.exe AuditSystem /L
Remove-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths\1" -Recurse -Force
```

## Lenovo Devices

Lenovo devices will display a progress when the DriverPacks is expanded

```powershell
Start-Process -FilePath $ExpandFile -ArgumentList "/SILENT /SUPPRESSMSGBOXES" -Wait

Write-Verbose -Verbose "$((Get-Date).ToString('yyyy-MM-dd-HHmmss')) Applying DriverPack with PNPUNATTEND"
New-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths" -Name 1 -Force
New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths\1" -Name Path -Value $DestinationPath -Force
pnpunattend.exe AuditSystem /L
Remove-Item -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UnattendSettings\PnPUnattend\DriverPaths\1" -Recurse -Force

## Microsoft Surface Devices

Microsoft uses MSI DriverPacks which expanded silently, so there is no activity in First Boot other than a long delay.  You can review the logs in C:\Windows\debug&#x20;

```powershell
$DateStamp = Get-Date -Format yyyyMMddTHHmmss
$logFile = '{0}-{1}.log' -f $ExpandFile,$DateStamp
$MSIArguments = @(
	"/i"
	('"{0}"' -f $ExpandFile)
	"/qb"
	"/norestart"
	"/L*v"
	$logFile
)
Start-Process "msiexec.exe" -ArgumentList $MSIArguments -Wait -NoNewWindow
```
