We already saw earlier how to boot ubuntu over ipxe with NFS

Howeber, setting an NFS server in windows is not always a given.

Hence, lets see now how to do it with a CIFS share i.e a simple windows share which Tiny PXE Server can manage for you.
Side note :
-I could make it work only with ubuntu 12.10, not 13.04.
-I could make it work only in plain DHCP mode, not proxydhcp mode.

needed :
ipxe
tiny pxe server
ubuntu

1/ open ubuntu.iso in winrar

(or any other iso reading capable tool)

extract casper folder to x:\pxe\iso\ubuntu.12.10 (or any path that suit you)

 

2/use the below ipxe script :

#!ipxe
set boot-url http://${dhcp-server}
kernel ${boot-url}/ubuntu.12.10/casper/vmlinuz showmounts toram root=/dev/cifs boot=casper netboot=cifs nfsroot=${cifs-server}/pxe/ubuntu.12.10 NFSOPTS=-ouser=username,pass=password,ro ip=dhcp ro
initrd ${boot-url}/ubuntu.12.10/casper/initrd.lz
boot

In the script above, adapt the username and password.
name it ubuntu.ipxe and put it in x:\pxe

Note :
About that syntax, as there is a controversy, be aware that I did not make it up.
Google it and you’ll find tons of similar examples and/or variants.
See my latest post abou this here.

 

3/put ipxe-undionly.kpxe in x:\pxe

 

4/modify config.ini with the following

(so that Tiny PXE Server will create a PXE share automatically for you pointing to your root folder) :
[dhcp]
smb=1

 

5/launch tiny pxe server with the following settings

(leave other settings untouched) :
tick « httpd »
boot filename = ipxe-undionly.kpxe (use the browse files and folders « … » button)
tick « filename if user-class=gPXE or iPXE » = http://${dhcp-server}/ubuntu.ipxe
push the online button

 

6/pxe boot your computer and here we go

7/ Notes

The same can be achieved with LinuxMint.

Extract the content of the iso to mint folder and use the ipxe script below :

#!ipxe
set boot-url http://${dhcp-server}
kernel ${boot-url}/mint/casper/vmlinuz showmounts toram root=/dev/cifs boot=casper netboot=cifs nfsroot=${cifs-server}/pxe/mint NFSOPTS=-ouser=username,pass=password,ro ip=dhcp ro
initrd ${boot-url}/mint/casper/initrd.lz
boot

1/open ubuntu.iso in winrar or 7zip (or any other iso reading capable tool).
extract casper folder to x:\pxe\iso\ubuntu.13.04 (or any path that suit you)

2/launch winnfsd with the following :

note : adapt the above path with your own path

3/use the below ipxe script :

note : adapt /x/pxe/ISO/ubuntu.13.04 to your own path.
name it ubuntu.ipxe and put it in x:\pxe

4/put ipxe-undionly.kpxe in x:\pxe

5/launch tiny pxe server with the following settings (leave other settings untouched) :

See previous article to understand why and what.

Previously we have created our differencing / child disks.

Lets first set our iscsi target with Starwind San Free by creating two targets and attaching one disk in each target.





Then lets boot our diskless computers over the network with TinyPXE Server.

We will use the below ipxe scripts (one for each network booting computer).
Replace ‘X’ below with the target number (1 or 2) on line 3 and 5.

#!ipxe
clear net0.dhcp/gateway:ipv4
set initiator-iqn iqn.2006-11.X
set keep-san 1
sanboot --keep iscsi:${next-server}:tcp:3260:0:iqn.2008-08.com.starwindsoftware:erwan-pc2-childX

And here we go, we have X diskless computers booted over the network using differencing disks on the iscsi target.

New in latest Tiny PXE Server version : some files served over the built-in HTTP daemon such as files with extension PHP, VBS and PY can be dynamically processed on the server side and not simply sent back as text/html files.

This gives one the ability to implement a logic on the server side thru php, vbscript or python, including parameters in the URL.

Other engines could be added later on such as node.js, perl, …

Example of ipxe script file on the client side (more reading here).

chain http://${next-server}/boot.php?param1=value1&param2=value2

Example of a boot.php file server side.

<!--?php //use $argv[1], $argv[2], etc to retrieve url parameters 
echo "#!ipxe\n"; 
echo "kernel ${boot-url}/wimboot\n"; 
echo "initrd ${boot-url}/bootmgr bootmgr\n"; 
echo "initrd ${boot-url}/boot/BCD BCD\n"; 
echo "initrd ${boot-url}/Boot/boot.sdi boot.sdi\n"; 
echo "initrd ${boot-url}/sources/boot.wim boot.wim\n"; 
echo "boot\n"; 
?-->  

The TinyPXE Server config.ini web section.

[web]
port=80
;php.exe file.php param1=value1
php=c:\_apps\php\php.exe
;cscript.exe file.vbs param1=value1 //nologo
vbs=C:\Windows\System32\cscript.exe
;python.exe file.py param1=value1
py=C:\Python27\python.exe

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)


#!ipxe
#dhcp net0
clear net0.dhcp/gateway:ipv4
set keep-san 1
sanhook iscsi:${next-server}:tcp:3260:0:iqn.2008-08.com.starwindsoftware:erwan-pc2-master
set boot-url http://${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 ||
boot

Second boot : lets boot to complete the windows installation


#!ipxe
#dhcp
clear net0.dhcp/gateway:ipv4
set initiator-iqn iqn.2006-11.1
set keep-san 1
sanboot --keep iscsi:${next-server}:tcp:3260:0:iqn.2008-08.com.starwindsoftware:erwan-pc2-master

Sharing a iPXE script (using wimboot) I am using these days along with Tiny PXE Server to boot winpe over the network on multiple platform : pcbios i386, pcbios x86_64, efi i386, efi x86_64.

Tiny PXE Server is serving by default pcbios ipxe.pxe and also, depending on the client architecture, serving the matching ipxe efi version.

See below my config.ini and a custom wimboot.ipxe script.

Discuss it here.

Following a post from 2014 about booting Winpe over PXE on a UEFI computer, see below a different way to proceed.

-Disable secureboot (or else you’ll need to use a signed bootloader)
-Retrieve latest version of IPXE for UEFI, ipxe-snponly-x86-64.efi and rename it bootia64.efi
-run the following command against your BCD : bcdedit.exe /store BCD /set {bootmgr} nointegritychecks yes
-Use the below wimboot.ipxe script based on Wimboot
-set Tiny PXE Server as below screenshot

wimboot.ipxe


#!ipxe
set boot-url http://${dhcp-server}
kernel ${boot-url}/wimboot
initrd ${boot-url}/bootmgfw.efi bootmgfw.efi
initrd ${boot-url}/EFI/MICROSOFT/BOOT/BCD BCD
initrd ${boot-url}/BOOT/BOOT.SDI BOOT.SDI
initrd ${boot-url}/SOURCES/BOOT.WIM BOOT.WIM
boot
