How to inject vioscsi driver into Windows install.win & boot.win using linux tools only ?

shodan · Saturday at 21:42

Hi,

I am trying to create a windows installer that has the virtio drivers builtin, for fully automatic and unattended installation.

In particular I am trying to inject the driver vioscsi into boot.wim and then install.wim

I can unpack and repack the iso.

I can inject actual driver files into the wim files

I think all that is left is to create the registery keys in the registery hive files,

The keys that need to be created, if I had a "reg add" command

Code:

REG ADD "HKLM\SYSTEM\CurrentControlSet\Services\vioscsi" /v Start /t REG_DWORD /d 0 /f
REG ADD "HKLM\SYSTEM\CurrentControlSet\Services\vioscsi" /v Type /t REG_DWORD /d 1 /f

But I would like to create cleaner, more reusable shell function for adding each node/key/values

Here is an untested attempt of ths reg_add shellfunction

Code:

reg_add() {
    local hive_file="$1"
    local registry_path="$2"
    local value_name="$3"
    local value_type="$4"
    local value_data="$5"

    if [[ -z "$hive_file" || -z "$registry_path" || -z "$value_name" || -z "$value_type" || -z "$value_data" ]]; then
        echo "Usage: reg_add /path/to/hive/file \"[registry_path]\" value_name value_type value_data"
        return 1
    fi

    # Convert the registry path for hivexsh
    local hive_path
    hive_path=$(echo "$registry_path" | sed -e 's/^\[//' -e 's/\]$//' -e 's|\\|/|g')

    # Run hivexsh commands
    hivexsh -w "$hive_file" <<EOF
cd $hive_path
setval 1
$value_name
$value_type:$value_data
commit
exit
EOF

    if [[ $? -eq 0 ]]; then
        echo "Successfully added \"$value_name\" to \"$registry_path\" in \"$hive_file\"."
    else
        echo "Failed to add \"$value_name\" to \"$registry_path\" in \"$hive_file\"."
        return 1
    fi
}

So we might then have a single shell function to just add vioscsi to a specified hive

Code:

#!/bin/bash

# Function to add vioscsi-related registry entries to a hive file
add_vioscsi_to_hive() {
    local hive_file="$1"

    if [[ -z "$hive_file" ]]; then
        echo "Usage: add_vioscsi_to_hive /path/to/hive"
        return 1
    fi

    if [[ ! -f "$hive_file" ]]; then
        echo "Hive file '$hive_file' not found."
        return 1
    fi

    echo "Adding vioscsi keys to hive: $hive_file"

I have created a shell function which can inject drivers files to all "image indexes" in the wim file

Code:

inject_filesandfolders_to_all_wim_images iso-master/sources/boot.wim \
virtio-unzipped/vioscsi/w10/amd64/vioscsi.cat /windows/inf \
virtio-unzipped/vioscsi/w10/amd64/vioscsi.inf /windows/inf \
virtio-unzipped/vioscsi/w10/amd64/vioscsi.sys /windows/system32/drivers

Shell function not fully tested

Code:

inject_filesandfolders_to_all_wim_images() { local wim_file="$1"; shift; local dest_folder="/"; local sources=(); for arg in "$@"; do [ -e "$arg" ] && sources+=("$arg") || { [ ${#sources[@]} -gt 0 ] && { dest_folder="$arg"; for source in "${sources[@]}"; do for i in $(seq 1 "$(wimlib-imagex info "$wim_file" | grep -i "Image Count" | awk '{print $NF}')"); do [ -d "$source" ] && echo "Injecting folder $source into image index $i at $dest_folder..." && wimlib-imagex update "$wim_file" $i --command="add $source $dest_folder" || [ -f "$source" ] && echo "Injecting file $source into image index $i at $dest_folder/$(basename "$source")..." && wimlib-imagex update "$wim_file" $i --command="add $source $dest_folder/$(basename "$source")"; done; done; sources=(); }; dest_folder="$arg"; }; done; [ ${#sources[@]} -gt 0 ] && { for source in "${sources[@]}"; do for i in $(seq 1 "$(wimlib-imagex info "$wim_file" | grep -i "Image Count" | awk '{print $NF}')"); do [ -d "$source" ] && echo "Injecting folder $source into image index $i at /..." && wimlib-imagex update "$wim_file" $i --command="add $source /" || [ -f "$source" ] && echo "Injecting file $source into image index $i at /$(basename "$source")..." && wimlib-imagex update "$wim_file" $i --command="add $source /$(basename "$source")"; done; done; }; }

then I repack the iso

create_windows_iso /mnt/iso/template/win10-repack/iso-master /mnt/iso/template/iso/Win10_22H2_EnglishInternational_x64_unattended-2025-1-10.iso

shell function not fully tested

Code:

create_windows_iso() { local src_folder="$1" out_iso="$2"; xorriso -as mkisofs -iso-level 3 -full-iso9660-filenames -volid "CCCOMA_X64FRE_EN-GB_DV9" -output "$out_iso" -eltorito-boot boot/etfsboot.com -eltorito-catalog boot/boot.cat -no-emul-boot -boot-load-size 8 -boot-info-table -eltorito-alt-boot -e efi/microsoft/boot/efisys.bin -no-emul-boot -boot-load-size 1 -isohybrid-gpt-basdat "$src_folder"; }

Code:

get_wim_image_count() { wimlib-imagex info "$1" | grep -i "Image Count" | awk '{print $NF}'; }

mount_wim_image() { local wim_file="$1" index="$2" mount_point="$3/$index"; [ -d "$mount_point" ] && [ "$(ls -A "$mount_point" 2>/dev/null)" ] && { echo "Error: Mount point $mount_point is not empty"; return 1; }; mkdir -p "$mount_point"; wimlib-imagex mount "$wim_file" "$index" "$mount_point" --rw; }

mount_wim_image() { local wim_file="$1" index="$2" mount_point="$3/$index"; [ -d "$mount_point" ] && [ "$(ls -A "$mount_point" 2>/dev/null)" ] && { echo "Error: Mount point $mount_point is not empty"; return 1; }; mkdir -p "$mount_point"; wimlib-imagex mount "$wim_file" "$index" "$mount_point" --rw; }

And now putting it all together

here using regular $WinpeDriver$ folder at root of the ISO.
straightforward, more easy, no need to update WIMs

shodan · Saturday at 22:59

I never heard of $WinpeDriver$

found

Important question is, will these drivers also get injected into the installed windows ?
Or will it crash after the reboot due to missing drivers ?

yes of course

shodan · 2025-01-26T00:03:38+0100

I was curious, why did distrobuilder windows repack did not use this special folder

https://github.com/lxc/distrobuilder/tree/main/windows

And I now realize, they skip the installer entirely.

We just create the filesystems and unpack install.wim directly into it, skipping the installer, at least the first step !

I did want a win10 iso that can cd/usb/net-boot and install windows to a baremetal/iscsi/VM but now I think for VMs it might be faster to skip portions of the installer if possible.

I also wish to incorporate
Microsoft-Windows-EMS-SAC-Desktop-Tools-FoD-Package~31bf3856ad364e35~amd64~~.cab

So that I can send terminal commands over serial to the running windows instance

sysprep is the way.
make a VM, go to audit mode
do your customs
snapshot (to allow rollback)
sysprep
backup VM with PVE (then restore to deploy VM)
or backup to WIM for baremetal.

shodan · 2025-01-26T00:41:26+0100

Maybe sysprep later, but for now I want a one-click "original iso to fully automated, finished install" function.
Maybe I can automate this sysprep and then clone the WIMs.

Just gave a try to the $WinPeDriver$ method

Here is how that went

Problems with that are
1. boot order missing ide2 to boot
2. Still need to "press a key to enter setup"
3. drivers aren't loaded

Why aren't the drivers loading ?

It appears the "$" characters have been replaced with "_" characters

Looking at the actual folder structure in the folder iso-master

Code:

root@proxmox:/mnt/iso/template/win10-repack/iso-master# ls
'$WinPeDriver$'   autorun.inf   boot   bootmgr   bootmgr.efi   efi   setup.exe   sources   support
root@proxmox:/mnt/iso/template/win10-repack/iso-master# find "\$WinPeDriver\$"/
$WinPeDriver$/
$WinPeDriver$/viomem
$WinPeDriver$/viomem/viomem.pdb
$WinPeDriver$/viomem/viomem.sys
$WinPeDriver$/viomem/viomem.inf
$WinPeDriver$/viomem/viomem.cat
$WinPeDriver$/qemupciserial
$WinPeDriver$/qemupciserial/qemupciserial.cat
$WinPeDriver$/qemupciserial/qemupciserial.inf
$WinPeDriver$/vioscsi
$WinPeDriver$/vioscsi/vioscsi.sys
$WinPeDriver$/vioscsi/vioscsi.cat
....

Looks good here, but strangely, the iso is wrong ??

So I went and mounted the iso file

Code:

root@proxmox:/mnt/iso/template/iso# mount -o loop /mnt/iso/template/iso/Win10_22H2_EnglishInternational_x64_unattended-latest.iso /mnt/test
mount: /mnt/test: WARNING: source write-protected, mounted read-only.
root@proxmox:/mnt/iso/template/iso# cd /mnt/test
root@proxmox:/mnt/test# ls
'$WinPeDriver$'   autorun.inf   boot   bootmgr   bootmgr.efi   efi   setup.exe   sources   support
root@proxmox:/mnt/test# find "\$WinPeDriver\$"/
$WinPeDriver$/
$WinPeDriver$/Balloon
$WinPeDriver$/Balloon/balloon.cat
$WinPeDriver$/Balloon/balloon.inf
$WinPeDriver$/Balloon/balloon.pdb
$WinPeDriver$/Balloon/balloon.sys
$WinPeDriver$/Balloon/blnsvr.exe
$WinPeDriver$/Balloon/blnsvr.pdb
$WinPeDriver$/fwcfg
$WinPeDriver$/fwcfg/fwcfg.cat
$WinPeDriver$/fwcfg/fwcfg.inf
$WinPeDriver$/fwcfg/fwcfg.pdb
$WinPeDriver$/fwcfg/fwcfg.sys
$WinPeDriver$/NetKVM

Strangely the iso is also fine, I wonder why ...

put only minimal drivers in $WinpeDriver$
netkvm and vioscsi
Then install with FirstLogonCommands of Autounattend.xml :
qemu drivers (win-gt.msi) and qemu agent (qemu-ga.msi)

edit : seems missing option ( joliet or udf version) for iso creation to fix missing $
Microsoft cdimage.exe use :
-u2 : Produces an ISO image that has only the Universal Disk Format (UDF) file system on it.

-udfver102 : Writes UDF revision 1.02 (Supported: Windows 98 and later)
