Installation of a new Windows PC with opsi (OS Installation)

The following describes how a computer with no operating system can get a Windows OS installed with opsi.

Suitable clients are real or virtual computers with at least 2048 MB RAM and a network card with network boot support: This means that they support the PXE protocol for booting systems via the network. The network boot has to be activated in the BIOS menu or moved to the first position of the bootorder options.

Virtual hardware is usually well supported by the Windows standard drivers, which can be tried if perform a test installation of Windows. To install Windows on newer real-world machines, you may need to integrate additional drivers first. For an initial test, you can use a lVMware Appliance that contains an empty machine and can run in VMware Workstation Player.

For the following chapter you should create a corresponding client in opsi [firststeps-osinstall-create-client]. This can be done easily through opsi-configed.

Some tools useful for deploying Windows with opsi are installed through the 'opsi-windows-support' package.

OS-Installation: Complete the Base Package for Windows

The opsi win-OS-packages contain only the files that are necessary to perform our automated OS installation, but not the operating system software itself.

For an automatic installation of a Windows operating system, you have to copy your existing original Windows installation files (and if necessary, store the Windows license key on the server).

NT6 family: Win7 / 2008R2 and up

In order to perform an OS Installation, a so-called WinPE is being used as a 'Live OS'. You can create it using an opsi package (opsi-winpe), or manually if you so desire. Generally speaking, the Windows version of the PE is independent of the Windows OS version being installed. Above all, the availability of drivers for disk- and network devices is important. Microsoft recommends a 32-Bit PE for 32-bit installations, and a 64-Bit PE for 64-bit installations.

'"To install a 64-bit version of Windows you must use a 64-bit version of Windows PE. Likewise, to install a 32-bit version of Windows, you must use a 32-bit version of Windows PE."'
https://technet.microsoft.com/en-us/library/cc766093.aspx

In any case you will need an "Windows PE add-on for the Assessment and Deployment Kit" (ADK, Windows 10 or 11), which you install on a supported (preferably 64-bit) Windows OS:

Windows ADK und Add-Ons

Install the Windows PE Add-On for ADK (if possible on a 64-bit machine) in the suggested path under Program Files (x86). Select only the "Windows Pre-Installation Environment (Windows PE)"; Dependencies are automatically selected.

Creating a PE

The simplest method requires a computer that has opsi-client-agent installed, as well as the Windows ADK (Win10, Win11). The manual method is described below in Manual PE creation for Windows 10 & Windows 11 (ADK).

Automated PE creation using opsi

Using opsi-configed set the localboot-product opsi-winpe to once for the client you intend to use, if desired adjust the product property to x86 instead of x64 at the lower right side, and save (right click > save).
If the opsi-product opsi-winpe is missing, install it onto your opsi-server with the command opsi-package-updater -v install opsi-winpe.
If storage drivers need to be integrated automatically, follow the method described below in Extending a PE using opsi.
Launch an installation event for the client (right click > on-demand, or reboot).
After a successful completion of this action, move or copy the contents of the now existing folder on your client C:\winpe_<ARCH>\media\ into the pre-existing folder within the OS folder you want to install: \\opsiserver\opsi_depot_rw\<operating system>\winpe\
Finally run the following command on the console of your opsi server. Finished.

opsi-set-rights

Manual PE creation for Windows 10 & Windows 11 (ADK)

The console commands are very similar in 32- or 64-bit versions, except for the <ARCH> entries. These have to be replaced with either x86 , amd64 or ia64.

Run Start ⇒ "Windows Kits" ⇒ "Windows ADK" ⇒ "Deployment and Imaging Toolkits Environment" from the Start Menu. A command prompt will open which has the required environment variables set.

Copy the WinPE

copype.cmd <ARCH> C:\winpe

Mount the Image

dism /Mount-Wim /WimFile:C:\winpe\media\sources\boot.wim /index:1 /MountDir:c:\winpe\mount

replace startnet.cmd

echo c:\opsi\startnet.cmd > "C:\winpe\mount\Windows\System32\startnet.cmd"

(Note: The file c:\opsi\startnet.cmd will be created by the opsi linux bootimage after the script setup.py is executed. The startnet.cmd contains the call to wpeinit.)

Unmount the Image

dism /Unmount-Wim /MountDir:c:\winpe\mount /Commit

Copy the contents of C:\winpe\ISO to /var/lib/opsi/depot/<productid>/winpe .
Adjust the access rights by entering:

opsi-set-rights /var/lib/opsi/depot/<productid>/winpe

Extending a PE

In some cases it is useful to extend a PE. Especially with hardware that is not supported by default in the PE.

Extending a PE using opsi

While automatically creating a PE with opsi-winpe, there is also an option to integrate drivers. Only integrate the drivers that are absolutely necessary to make windows setup work properly. For instance, storage and network devices that are not supported in the PE, which then cause the installation to fail.

Copy the drivers to \\opsiserver\opsi_depot_rw\opsi-winpe\drivers\ and set the access rights by running:

opsi-set-rights /var/lib/opsi/depot/opsi-winpe

After this, just follow the steps in: Automated PE creation using opsi If everything has worked correctly there will be a mention of the integrated drivers in the logfile. This is an example when a VirtIO storage controller has been integrated:

Extending a PE manually

Dell provides special network and storage drivers specially recommended for use in a PE. These instructions assume that you have already completed the previous chapter and have created a PE.

The Windows Automated Installation Kit is not needed for following instructions.

The first step is to download Dell-PE-drivers from the Dell-Website. The downloaded CAB-File must be extracted to the local disk. This can be done with 7-zip or the command-line-tool Expand.exe. For simplicity, we recommend creating a directory called "dell-driver" on the local disk, and then extracting the CAB-File into this directory.

First dism is used to scan the image, in order to determine the required index number. Start an elevated command prompt as administrator and run the following command:

dism /Get-WimInfo /WimFile:C:\winpe\ISO\sources\boot.wim

In the output of this command, you can see which images are included in the image file. Normally a PE-image is a one-image-file, so you can generally use the index 1, but it is better to check first.

The next command mounts the image for modification:

dism /Mount-Wim /WimFile:C:\winpe\ISO\sources\boot.wim /index:1 /MountDir:c:\winpe\mount

To integrate the extracted drivers into the mounted image, you need to execute this command:

dism /Image:C:\winpe\mount /Add-Driver /Driver:c:\dell-driver\winpe\x64 /Recurse

If the architecture is 32-bit, the x64 must be replaced with x86. The Driver-CAB from Dell contains the drivers for both architectures.

If only one driver has to be integrated, then leave out the option /Recurse, and point directly to the driver-inf-File instead of the driver-directory. Furthermore, with the option /ForceUnsigned it is possible to integrate unsigned drivers to the image.

Finally the image is unmounted, and the changes are committed:

dism /Unmount-Wim /MountDir:c:\winpe\mount /Commit

Copy the contents of C:\winpe\ISO to /var/lib/opsi/depot/<productid>/winpe.
Adjust the access rights by entering:

opsi-set-rights /var/lib/opsi/depot/<productid>/winpe

unattend.xml

The control file for the unattended installation is the XML file unattend.xml, which you can find under /var/lib/opsi/depot/<productid>/custom. Any modifications to this file should be made in this directory and not in the opsi directory.

The file unattend.xml that comes with the opsi package, contains references to the netboot productproperties, which among other things is responsible for activating the Administrator account with the password 'nt123'.

Driver Integration

The driver integration proceeds as described here: Simplified Driver Integration during the unattended Windows Installation.

Providing the Installation Files

Copy the complete installation DVD to
/var/lib/opsi/depot/<productid>/installfiles And adjust the rights and ownership:

opsi-set-rights /var/lib/opsi/depot/<productid>/installfiles

Installation Log files

c:\Windows\Panther\setupact.log:
Log until the end of setup phase 4 (running under WinPE)
c:\Windows\Panther\setupact.err:
Error log until the end of setup phase 4 (running under WinPE)
c:\Windows\Panther\UnattendGC\setupact.log:
Log from the specialize phase
c:\Windows\Panther\UnattendGC\setupact.err:
Error log from the specialize phase
c:\Windows\System32\Winevt\Logs\*
c:\Windows\ntbtlog.txt (only when startup logging is activated)

Windows Product Key

If you have the opsi license management module, you can manage the Windows product keys using the license management module. Read the license management manual or the corresponding chapter in the opsi manual.

If you do not have the license management module, or do not want to use it, proceed as follows.

If you have already set up opsi clients, you can enter a Windows product key per client in the opsi configuration editor:

select a client
switch to the netboot products tab
select the product (e.g. win10-x64)
change the product property productkey in the lower right corner
enter the key in the value field
save by clicking on the "red tick" and leave the field
save the changes in the backend ("red tick" at the top right).

Or you can assign a default for the Windows product key for the complete opsi depot, which can also be done via the opsi configuration editor:

Select the depot properties in the configuration editor (tile top right)
Switch to the Product Default Properties tab
select the product (e.g. win10-x64)
Go to the property line productkey in the switch list on the right
Enter the key in the value field and add it by clicking on "+"
save by clicking on the "red tick" and leave the field
save the changes in the backend ("red tick" at the top right).

Start the Windows Installation

To start a Windows installation, select the relevant client in opsi-configed, set in the 'Netboot products' tab the action to 'setup' for the desired operating system (e.g. win10-x64). Click on the red checkmark (which turns green again).

The client should now load the opsi-linux-bootimage via the network when booting, where you have to confirm the new OS installation again. Then everything should continue automatically until the logon prompt of the installed Windows is finally on the screen.

If the screen remains black after loading the boot image or the network card does not work correctly, the start parameters of the boot image may have to be adjusted for this specific hardware.
You can do this in 'opsi-configed' in the 'Host parameters' tab at the entry 'opsi-linux-bootimage.append'.
You can find details on this in the opsi manual in the 'Netboot Products' chapter.

Beware of clients with a hard disk larger than 2 TB. In a non-UEFI system, the maximum partition size is 2 terabytes. If a larger partition is to be created, the installation will fail. This a technical limitiation of the standard partition table. You need to split the hard drive into partitions. You can control this via the product properties. Or you can purchase the UEFI module, which eliminates this technical limitation.

File Descriptions

setup.py
This is the installation script which is executed by the boot image.
<productid>_<version>.control
Contains the metadata of the product as prepared from the package maintainer. These files are here for information purposes only. Changes to this file have no effect on the system.
<productid>.files
This file is created automatically and should not be changed.
create_driver_links.py
show_drivers.py
These scripts are for driver integration, which is explained in more detail in the chapter Simplified driver integration in the automatic Windows installation.

Directory installfiles / winpe

installfiles
This directory contains all files from the installation CD/DVD.
winpe
Contains a bootable winpe image.

Directories opsi and custom

These two directories contain scripts and configuration files for controlling the operating system installation. During installation, priority is given to files in the custom directories.

The opsi directory contains files that can be overwritten without notice by updates. So no changes to these files should be made. For adjustments, you can make changes in the directory custom, which is preserved during updates.

The subdirectory postinst.d contains scripts which are started via the` postinst.cmd` after the actual installation of the operating system, e.g. to install the opsi-client-agent. The scripts are processed in alphabetical order. To clarify the order of execution, the file names begin with a two-digit number (10_dhcp.cmd). If you want to make extensions here, you can store scripts in the custom/postinst.d directory with starting numbers between decades (13_myscript.cmd). The starting numbers 10, 20, 30,… are reserved for maintenance by opsi.org/uib. The script 99_cleanup.cmd is the final script and ends with a reboot.

Directory drivers

This directory is used for the integration of drivers and is described in the following chapter.

Simplified Driver Integration during the unattended Windows Installation

When managing a group of PCs that have devices whose drivers are not included in the standard Windows installation, it usually makes sense to integrate these drivers directly into the installation. In the case of network devices, this can sometimes be unavoidable, because a Windows without a network card is not easily accessible for the administrator.

Opsi supports the automatic integration of drivers into the installation, and therefore simplifies driver deployment. The drivers simply need to be placed into the correct directory. By executing a script, the driver directories are searched and a catalog is created, based on which the bootimage can automatically identify and integrate the correct drivers. Standard drivers, USB drivers, HD audio drivers as well as drivers for hard disk controllers (text mode drivers) can be stored and automatically integrated.

In order for the drivers to be installed with the Windows installation, they must be stored in a specific form on the server. Suitable drivers contain a '*.inf' file that describes the driver for the Windows Setup program. Any drivers in setup.exe, '*.zip' or packed any other way are not usable. If you have a computer that already has the drivers installed, then you can extract the drivers in the correct format with the program 'Double Driver'.

There are multiple levels of driver integration:

General driver packages
Drivers that are suitable for your hardware but are not specially assigned
Drivers that are manually assigned to computers
Drivers that are automatically assigned to the computers via the <vendor>/<model> fields of the inventory.

How these different levels can be used is described below:

General Driver Packages

When the hardware configuration across the computers is very heterogeneous, then it can make sense to work with general driver packages.
General drivers can be placed under ./drivers/drivers.

Drivers which are found in ./drivers/drivers/, will be matched to the corresponding hardware using the PCI IDs (or USB- or HD_Audio-IDs) in the description file, and then integrated into the Windows setup if needed.

Drivers that suitable for your hardware but not specially assigned

In case you have to support few different hardware configurations, you can use the drivers provided by the manufacturers.
Additional or tested drivers belong in their own directories (name and depth of the directory structure do not matter) below the directory
./drivers/drivers/preferred.
Drivers located in the directory ./drivers/drivers/preferred are prioritised over the drivers in ./drivers/drivers/ by using the PCI IDs (or USB- or HD_Audio-IDs) in the description file, and then integrated into the Windows setup if needed.
Problems can occur when the same PCI ID can be found in the description file of different drivers in preferred. In this case a direct assignment of the drivers to the client is necessary.

Drivers manually assigned to clients

Additional drivers that are to be installed regardless of their assignment or detection via the PCI- or USB-IDs must be in their own directories (name and depth of the directory structure are irrelevant) below the directory ./drivers/drivers/additional. Via the product property 'additional_drivers' you can assign one or more paths of driver directories within ./drivers/drivers/additional to a client. Directories specified in the 'additional_drivers' product property are searched recursively and all included drivers will be integrated. Symbolic links are also followed. You can use this to create a directory for certain computer types (e.g. dell-optiplex-815).

If a driver for a matching PCI device (or HD audio, USB) is found in the driver directories specified via 'additional_drivers', then no other driver from drivers/preferred or drivers/ is integrated for this device ('additional_drivers' can be thought of as 'super-preferred'). This means that 'additional_drivers' has the function of adding drivers that would not be found via normal driver detection.

Drivers automatically assigned to the clients using the inventory fields

The mechanism of direct assignment of drivers to devices described in the previous section can be automated since opsi 4.0.2. The directory ./drivers/drivers/additional/byAudit is searched for a directory name that corresponds to the 'vendor' found during hardware inventory. A search is now made in this 'vendor' directory for a directory name that corresponds to the 'model' found during hardware inventory. If such a directory is found, this directory is treated as if it were manually assigned via the product property 'additional_drivers'. The directory name 'byAudit' is case sensitive. The directory names for 'Vendor' and 'Model' are not case sensitive ('Dell' and 'dELL' are treated the same way).

Since opsi 4.0.5, the drivers for a opsi-client can be made available via opsi-configed in the Hardware Inventory tab (see: opsi manual "Automatic driver upload").

The opsi-linux-bootimage looks for drivers in the order:

<vendor>/<model> (<sku>)
if in the previous no match is found <system vendor>/<system model> is checked.
if in the previous no match is found <motherboard vendor>/<motherboard model> is checked.

Some manufacturers use model names, which are very unfavourable for this method, because you can not use some special characters such as / in file- or directory names. An example of this would be a model name like: "5000/6000/7000". A directory with this name is not permitted due to the special characters. Since opsi 4.0.3 the following special characters: < > ? " : | \ / * have therefore been replaced internally by a _. With this change you can create the directory for the example as: "5000_6000_7000" and the directory is automatically assigned, although the information in the hardware inventory does not correspond to the directory structure.

                 |-exclude/		(excluded drivers)
                 !-mydriverpacks/	(example driver packages)

Processing of the Different Levels of Driver Integration

The top priority is to include all drivers that are found using the property 'additional_drivers' or using the inventory data in ./drivers/drivers/additional/byAudit. As part of the integration of drivers, it is checked for which hardware of a device (based on the PCI-, USB-, HD-Audio IDs) a driver has been made available in this way. Only for devices that are not matched by a driver, the following methods are used in order to find a matching driver.

For devices for which a driver has not been assigned via 'additional_drivers' (or 'byAudit'), a suitable driver is searched for and integrated using the PCI ID (or USB-, HD-Audio ID).

'Integration' of drivers means the following:

The driver will be copied to the local hard drive at c:\drv\<num>.
The Windows Setup is told in the unattended file to search for matchin drivers in c:\drv\.

Add and check drivers

After adding a driver or any other change in the ./drivers/drivers directory (or below), execute the following command in the root directory of the netboot product directory to set the rights correctly:

opsi-set-rights ./drivers

After storing drivers in the directories ./drivers/drivers or ./drivers/drivers/preferred, then run the script ./create_driver_links.py. The script searches the directories under './drivers/drivers' and generates a list of links that can be used to identify the assignment of the drivers to specific hardware (PCI-IDs, USB-IDs and HD-Audio-IDs). The script will prioritize the drivers in the preferred directories.

The script setup.py of the bootimage examines the hardware of the computer to be installed and identifies the necessary drivers. These are then copied to the hard disk and the unattend.xml will be patched accordingly.

If a hardware inventory is available for a client, you can use the command:

./show_drivers.py <clientname>

This will show which drivers the boot image would choose for installation via PCI-IDs, USB-IDs, HD-Audio-IDs and 'additional_drivers' (or 'byAudit') and for which hardware no driver is available yet.

Use the output of show_drivers.py to check if the desired drivers will be integrated.

It is possible that driver directories from manufacturers contain drivers for different operating system versions (e.g. Windows 7/8.1/10) or different configurations (SATA / SATA-Raid). This cannot be differentiated automatically. If you suspect that the wrong driver will be used, move this driver to the drivers/exclude directory and then run create_driver_links.py again. Drivers in the directory 'drivers/exclude' are not used during driver integration.

Example output of show_drivers.py for a client:

./show_drivers.py pcdummy

Some chipset drivers contain description files, which specify hardware without actually providing drivers. An example would be the cougar.inf or ibexahci.inf from Intel. If such a 'pseudo driver' directory is assigned via 'additional_drivers' (or 'byAudit'), this means that the hardware listed here is excluded from further searches for drivers in the 'preferred' directory.
SATA drivers and SATA-RAID drivers refer to the same PCI ID. However, a SATA RAID driver will not function with a single-disk system.
Check the output of ./show_drivers.py carefully!
