See previous article to understand why and what.

In this article, we will see how to create our master / parent VHD and how to install windows onto this disk.

To manipulate virtual hard disks on the command line, i use vmount.

Create parent vhd
vmount createdynamic e:\_images\iscsi.vhd 102400
Attach vhd as physical disk without a drive letter
vmount attach e:\_images\iscsi.vhd NOLETTER
Check it out
vmount disks

At this stage, we have a new \\.\physicaldriveX on your host which we can use within our iscsi target (using Starwind San Free).

Last step, lets boot our diskless computer to install windows.
To do this, I will use TinyPXE Server and iPxe.
I also use QuickPE to customize my winpe (but default ms waik or adk will do as well).

First boot : we will attach our iscsi disk then boot our WinPE from where we will launch windows setup (over a network share)

#dhcp net0
clear net0.dhcp/gateway:ipv4
set keep-san 1
sanhook iscsi:${next-server}
set boot-url http://${dhcp-server}
echo ${platform}_${buildarch}
kernel ${boot-url}/wimboot
iseq ${platform} pcbios && initrd -n bootmgr.exe ${boot-url}/BOOTMGR.EXE bootmgr.exe ||
iseq ${platform} efi && initrd -n bootmgfw.efi ${boot-url}/bootmgfw.EFI bootmgfw.efi ||
iseq ${platform} pcbios && initrd -n bcd ${boot-url}/BOOT/BCD bcd ||
iseq ${platform} efi && initrd -n bcd ${boot-url}/EFI/MICROSOFT/BOOT/BCD bcd ||
initrd ${boot-url}/BOOT/BOOT.SDI BOOT.SDI
iseq ${platform} pcbios && initrd -n boot.wim ${boot-url}/SOURCES/x86/BOOT.WIM BOOT.WIM ||
iseq ${platform} efi && initrd -n boot.wim ${boot-url}/SOURCES/x64/BOOT.WIM BOOT.WIM ||

Second boot : lets boot to complete the windows installation

clear net0.dhcp/gateway:ipv4
set initiator-iqn iqn.2006-11.1
set keep-san 1
sanboot --keep iscsi:${next-server}

  1. […] –create the master / parent disk -create the differencing / child disks -boot diskless computers over the network using these child disks […]
