This walkthrough describes how to set up a third-party Preboot Execution Environment (PXE) server by using Windows® PE 2.0. The process includes copying Windows PE 2.0 source files to your PXE server and then configuring your PXE server boot configuration to use Windows PE.
Prerequisites
To complete this walkthrough, you need a technician computer, which provides all the tools and the source files. For more information, see Building a Technician Computer.
Step 1: Copy Source Files onto PXE Server
In this step, you copy Windows PE source files to your PXE server.
- On your technician computer, click Start, point to
Programs, point to Windows OPK or
Windows AIK, and then click Windows PE Tools
Command Prompt.
The menu shortcut opens a Command Prompt window and automatically sets environment variables to point to all the necessary tools. By default, all tools are installed at C:\Program Files\<version>\Tools, where <version> can be Windows OPK or Windows AIK.
- Run the Copype.cmd script. The script requires two arguments:
hardware architecture and destination location.
copype.cmd <arch> <destination>
copype.cmd x86 c:\winpe_x86
C:\winpe_x86 C:\winpe_x86\ISO C:\winpe_x86\mount
- Mount the base Windows PE image to the \Mount directory by
using the ImageX tool. For example,
imagex /mountrw C:\winre_x86\winpe.wim 1 C:\winpe_x86\mount
- Map a network connection to the root TFTP directory on the
PXE/TFTP server and create a \Boot folder. For example,
net use N: \\<PXEServer>\TFTPRoot md N:\Boot
- Copy the PXE boot files from the mounted directory to the \Boot
folder. For example,
cd \temp\Windows\Boot\PXE copy c:\winpe_x86\mount\Windows\Boot\PXE\*.* N:\Boot
- Copy the Boot.sdi file to the PXE/TFTP server.
copy c:\Program Files\<version>\Tools\PETools\x86\boot\boot.sdi N:\Boot
- Unmount the current Windows PE image and copy the bootable
Windows PE image to the \Boot folder.
Imagex /unmount C:\winpe_x86\mount copy c:\winpe_x86\winpe.wim N:\Boot\boot.wim
Step 2: Configure boot configuration
In this step, you create a BCD Store by using the BCDEdit tool. The BCDEdit tool can be run only from a Windows® 7 computer or a Windows PE environment. The BCDEdit tool is located in the \Windows\System32 directory.
- On a Windows® 7 computer or in a Windows PE
environment, create a BCD store by using the BCDEdit tool. For
example,
Bcdedit -createstore c:\BCD
- Create the RAMDISK settings. For example,
Bcdedit -store c:\BCD -create {ramdiskoptions} /d "Ramdisk options" Bcdedit -store c:\BCD -set {ramdiskoptions} ramdisksdidevice boot Bcdedit -store c:\BCD -set {ramdiskoptions} ramdisksdipath \boot\boot.sdi
- (Optional) Create kernel debugger settings. For example,
Bcdedit -store c:\BCD -create {dbgsettings} /d "Debugger settings" Bcdedit -store c:\BCD -set {dbgsettings} debugtype serial Bcdedit -store c:\BCD -set {dbgsettings} baudrate 115200 Bcdedit -store c:\BCD -set {dbgsettings} debugport 1
- Create OSLoader settings for the Windows PE image. For
example,
Bcdedit -store c:\BCD -create /d "MyWinPE Boot Image" /application osloader
guid1
.
Bcdedit -store c:\BCD -set {guid1} systemroot \Windows Bcdedit -store c:\BCD -set {guid1} detecthal Yes Bcdedit -store c:\BCD -set {guid1} winpe Yes Bcdedit -store c:\BCD -set {guid1} osdevice ramdisk=[boot]\Boot\boot.wim,{ramdiskoptions} Bcdedit -store c:\BCD -set {guid1} device ramdisk=[boot]\Boot\boot.wim,{ramdiskoptions}
- Create the BOOTMGR settings. For example,
Bcdedit -store c:\BCD -create {bootmgr} /d "Windows BootManager" /inherit {dbgsettings} Bcdedit -store c:\BCD -set {bootmgr} timeout 30 Bcdedit -store c:\BCD -displayorder {guid1} {guid2}
guid1
,guid2
, and so on are the GUIDS for each .wim file entry.
- Copy the BCD file to your server. For example,
copy c:\BCD N:\Boot
- Configure your PXE/TFTP server to point PXE clients to download
WDSNBP.COM.
Your PXE/TFTP server is now configured.
Deployment process
The following outlines the download process.
- A client is directed (by using DHCP Options or the PXE Server
response) to download Wdsnbp.com
- Wdsnbp.com validates the DHCP/PXE response packet and proceeds
to download PXEBoot.com.
- PXEBoot.com downloads Bootmgr.exe and the BCD store. The BCD
store must reside in a \Boot directory in the TFTP root folder.
Additionally, the BCD store must be called BCD.
- Bootmgr.exe reads the BCD operating system entries and
downloads Boot.sdi and the Windows PE image .
- Bootmgr.exe begins booting Windows PE by running
Winload.exe within the Windows PE image.
