Hi George1421.
Thanks for the great tutorials.
Two questions:
Do you have an up to date tutorial for using SystemRescueCD (recent version is 5.2.2 i believe)
And more pressing:
When I follow your Ubuntu 17.10 Desktop instructions, everything works fine until I actually try to boot, when the boot process starts I get a Kernel panic:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,255)Then some more lines and at the end again the same error message.
Any idea on what could be causing this?
Edit: Just noticed that I used 17.10.1, not 17.10, will try with 17.10 and report back - aaand, there is no 17.10 “non-.1” on the official ubuntu download page

ref: https://forums.fogproject.org/topic/10944/using-fog-to-pxe-boot-into-your-favorite-installer-images/11Please post what you have for your fog ipxe menu configuration. The error basically means that the kernel doesn’t understand the virtual hard drive (initrd.lz)
-
My fog ipxe menu item has the following parameters:
kernel tftp://${fog-ip}/os/ubuntu/Desk17.10/vmlinuz.efi initrd tftp://${fog-ip}/os/ubuntu/Desk17.10/initrd.lz imgargs vmlinuz.efi root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:/images/os/ubuntu/Desk17.10/locale=de_AT.UTF-8 keyboard-configuration/layoutcode=de quiet splash ip=dhcp rw boot || goto MENU -
@taspharel So you have the kernel and init in the /tftpboot/os/… path and the entire DVD in the /images/os/… path?
-
Yes.
the DVD is extracted to /images/os…
The Kernel and init are in the tftpboot-pathThe kernel and init load when I select the Ubuntu Entry in my FOG Menu, but after that when Ubuntu seems to take over -> error.
-
I seem to have a similar problem when trying to run System Rescue Disk via PXE. Also something about not finding root or along those lines.
Will try booting on another machine to make sure that its not related to the Lenovo Laptop I am using …
-
@taspharel What are you having issues with, with SystemRescueCD? I just downloaded the ISO and you should be able to extract it and make it boot via pxe. There is a kernel file and an initrd file.
I’m currently in the process of downloading ubuntu desktop 17.10.1 to see if there is a difference.

@george1421 Hey, re: our pm’s with winpe and UEFI, I am still having trouble. Let me know if you would rather I create a new post for my issue or if its ok to carry on here.
kernel http://${fog-ip}/fog/os/win/wimboot gui initrd --name BCD http://${fog-ip}/fog/os/win/winpe/am64/media/Boot/BCD BCD initrd --name boot.sdi http://${fog-ip}/fog/os/win/winpe/amd64/media/Boot/boot.sdi boot.sdi initrd --name boot.wim http://${fog-ip}/fog/os/win/winpe/amd64/media/sources/boot.wim boot.wim boot || goto MENUIt loads the files, has about a dozen lines about patching the WIM file, says its loading ‘bootx64.efi’ and then just reboots (machine makes a single beep). It never gets to loading the winpe environment. BIOS it boots fine and moves on to winpe.
I tried with/without:
- ‘gui’ (on the kernel line)
- ‘pause’ (on kernel line)
- ‘rawbcd’ (on gui line)
None of the above changed anything. I also rebuilt my winpe files using copype amd64 /path and still had same issue. When re-creating (using copype) I didnt even bother adding the commands to connect to network and run installer.
I have seen others add 4 lines for fonts, I am going to give that a shot too. I also am searching for another viable test box to ensure its not just the specific hardware I am using.
I am running copype on a Windows Server 2016 box with newest MDT and ADK. wimboot is latest, 2.6.0 I think (on FOG machine).
Any help would be awesome, Thanks!
EDIT: ok must be something about the Dell Precision Tower 3620. UEFI boot worked on an R620. I even added the latest Dell Winpe 10 drivers to the boot.wim and still get the crash when UEFI booting. Still could use a solution, but it may end up just being that this specific model is allergic to ipxe/winpe

@zer0cool said in Problems with using-fog-to-pxe-boot-into-your-favorite-installer:
http://${fog-ip}/fog/os/win/winpe/amd64/media/Boot/boot.sdi boot.sdi
This is a risky path to place your files in. At the very least I would move them out of the /var/www/html/fog directory. The fog installer has been known to remove unexpected files in its path. My instructions suggest to use tftp protocol for testing.
-
@george1421 I symlinked my /tftpboot to var/www/html/fog/ so that everything i do under tftpboot in the os folder is available via http.
Turns out this works…
kernel http://${fog-ip}/fog/os/win/wimboot pause gui initrd --name segmono_boot.ttf http://${fog-ip}/fog/os/win/winpe/amd64/media/Boot/Fonts/segmono_boot.ttf segmono_boot.ttf initrd --name segoe_slboot.ttf http://${fog-ip}/fog/os/win/winpe/amd64/media/Boot/Fonts/segoe_slboot.ttf segoe_slboot.ttf initrd --name segoen_slboot.ttf http://${fog-ip}/fog/os/win/winpe/amd64/media/Boot/Fonts/segoen_slboot.ttf segoen_slboot.ttf initrd --name wgl4_boot.ttf http://${fog-ip}/fog/os/win/winpe/amd64/media/Boot/Fonts/wgl4_boot.ttf wgl4_boot.ttf initrd --name BCD http://${fog-ip}/fog/os/win/winpe/amd64/media/Boot/BCD BCD initrd --name boot.sdi http://${fog-ip}/fog/os/win/winpe/amd64/media/Boot/boot.sdi boot.sdi initrd --name boot.wim http://${fog-ip}/fog/os/win/winpe/amd64/media/sources/boot.wim boot.wim boot || goto MENUHad to add the 4 lines for fonts and now it boots in UEFI. I am amazed this was the issue and only on this machine. The fonts btw where in the locations, so its not like moving them into tftpboot was a problem. It was explicitly placing the initrd lines for the fonts in the ipxe entry that made it work…go figure.

Hi there,
@george1421
I just noticed that on Linux Mint 19 and newer it’s not possible to boot anymore before you change the Boot Parameter! I got it going on after setting this:imgargs vmlinuz root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:/var/www/html/iso/mint/ locale=de_DE.UTF-8 keyboard-configuration/layoutcode=de ip=dhcp toram -- || read voidKeep in mind, I got a different folder! But the parameter toram is damn important, otherwise it’s not able to mount /tmp and goes into emergency mode!
Maybe you want to update the wiki?
-
@Gamienator Thank you for the feedback and info, I will get the tutoral updated right away.

Hey peeps,
I’ve managed to get the installer portion running using a plethora of info out there but what really worked for me is this:
Downloaded vmlinuz and initrd.gz from the netboot version of Ubuntu and placed them into the tftp root folder:
Created a folder in /images/os called ubuntu and used 7z to extract Ubuntu 18.04 iso into this folder.
My menu entry now looks like this:
kernel tftp://${fog-ip}/ubuntu/vmlinuz initrd tftp://${fog-ip}/ubuntu/initrd.gz imgargs vmlinuz initrd=initrd.gz root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:/images/os/ubuntu splash ip=dhcp rw bootIt now boots on any machine into an Ubuntu Installer BUT!
This is great but not my final wish.
Is there a way to avoid the straight to install process and at least load a Live CD so that I could use Ubuntu to say scan the PC’s drive with clamav?
Any help would be great!
Thanks.

The linux mint 19 maybe a bit closer to the kernel used in 18.04: https://forums.fogproject.org/topic/10944/using-fog-to-pxe-boot-into-your-favorite-installer-images/17

@george1421 Fantastic!!! I got Mint running and booting live over the network. Thank you so much for the info.
For everyone’s use I created:
/images/os/mint where I used 7z to extract the entirety of the mint.iso
/tftpboot/mint where I placed the vimlinuz and initrd.lz from the casper folder in the previously mentioned extracted iso.My menu item in PXE is now this:
kernel tftp://${fog-ip}/mint/vmlinuz initrd tftp://${fog-ip}/mint/initrd.lz imgargs vmlinuz initrd=initrd.lz root=/dev/nfs boot=casper netboot=nfs nfsroot=${fog-ip}:/images/os/mint systemd.mask=tmp.mount ip=dhcp rw bootBoots great!! ClamAV scanning of Windows drives here I come!

I hate to beat a dead horse, but I just wanted to say thank you for this in depth tutorial. It is amazing. Thank you!
-
I just wanted to add to this -
If you have an antique server that totally and completely lacks UEFI support (such as my ML350 Gen8) then you can just follow the instructions that @george1421 posted for Windows ISO’s to boot any (most) ISO’s in legacy mode. I just tested it with VMWare 6.7U2 on the HP ML350 Gen8, worked flawlessly. -
Can I just check that https://forums.fogproject.org/topic/10944/using-fog-to-pxe-boot-into-your-favorite-installer-images/19 is still the latest information please.
Also, if I wanted to script the changes to the fog menu (ansible or bash) do you know where I’d start looking for the boot menu options please?
-
@beardedfool AFAIK nothing has changed for ubuntu 16.04 in years. Are you having a specific issue? I can tell you later versions of ubuntu also boot using this method. In general if I add something to the that netbooting thread I’ve personally set it up and tested.
I’m not sure I understand about scripting changes to the fog menu. The fog menu is powered by the FOG server. The fog server has built in management to add or remove entries in the iPXE menu. The language that powers the FOG iPXE menu is ipxe’s own programming language. You can see this programming language in action by opening up a web browser and pointing to this URL.
http://<fog_server_ip>/fog/service/ipxe/boot/php?mac=00:00:00:00:00:00The fog iPXE menu is specifically crafted by the fog script boot.php on the fog server.If you could could provide a bit more details on what you want to change I might be able to give you a direction to look in.
