Thank you for your detailed reply, @george1421

I have decided to run both servers on the same network. With DHCP switched off on AikenWorkbench, I’m able to boot intoFOG menu.

Your entries aren’t quite right, or I’m doing something wrong. If I use it as is, I’m getting something like "Could not boot: Not found (https://ipxe.org2d12618e)

I have decided to exclude some of the commands and narrowed it down to:

chain -ar tftp://192.168.2.1/grub/bootx64.efi boot || goto MENU

And I’m trying to run it on EFI EFI-capable machine, but I’m only getting to the grub console and no further.

I understand my best bet is to learn how iPXE works and study its documentation.

There is more config from Aken if this helps:

cat /etc/default/tftpd-hpa TFTP_USERNAME="tftp" TFTP_DIRECTORY="/awbcboot" TFTP_ADDRESS="192.168.2.1:69" TFTP_OPTIONS="--secure" ls /awbcboot bios biso boot grub ls /awbcboot/grub biso boot bootx32.efi bootx64.efi grub.cfg grub.cfg.bak snap unicode.pf2

And grub.cfg

cat grub.cfg set default="0" set timeout=0 menuentry 'Aiken Workbench V2 UEFI ...' --class gnu-linux --class gnu --class os { linux (pxe)/boot/vmlinuz-awc root=/dev/nfs nfsroot=${pxe_default_server}:/awbclient ip=dhcp rw libata.allow_tpm=1 -- initrd (pxe)/boot/initrd.img-awc

And here is the whole dhcp.conf but we don’t use Apple class as they dropped PXE support.

@Tom-Elliott I fixed it by directly removing the dirty flag using Linux. sudo ntfsfix -d /dev/nvme...

We need to redo our golden image, so we will check at that time if we still get the same behavior.

Thx for the help !

@george1421

I’ve reinstalled FOG, using the in-built DHCP server instead of the router.
Worked perfectly first time, after setting the router as a relay instead.

Thank you very much for all your help! 🙂

@Faurel ok good that looks like a clean dhcp process. It would be helpful to have the pcap file in my hand, but you want to expand the OFFER packet. The OFFER packet you can tell from the Info column.

In the packet you may need to expand the dhcp section. You should see the image similar to below. What is important is the next server IP address should point to IP address of your fog server. and boot file name should be ipxe.efi. You see in this example that the boot file name was not given, this is the error with this packet. The next server and boot file are in the ethernet header. This is the legacy bootp pxe section.

The next place you need to check is the dhcp options below. You should see dhcp options 66 which should be the IP address of the fog server and dhcp 67 should be the boot file name of ipxe.efi. In this picture this packet is also in error since the dhcp server is not sending out all of the pxe booting info. So if your offer packet looks like this you have a problem.

Any luck clearing up this error? Running into the same thing now setting up a separate storage node location(still local). I get this when trying to deploy an image.

This tutorial will give you a good general overview. https://forums.fogproject.org/topic/10944/using-fog-to-pxe-boot-into-your-favorite-installer-images

Since you are talking XP, then you are also meaning bios firmware. For bios you can use a utility called memdisk.

https://forums.fogproject.org/post/142041 step #18. The memdisk program is only supported under a bios based computer. If you have uefi there is a different process. There are some limitations with bios mode, your iso file MUST be less than 2GB, this is a limitation of a 32 bit bios.

@Pingu Ok, i find out that my /images was a little bit bugged and got my snapshots in dev folder with the mac address as name folders, i moved them into /images and renamed them with the image name i configured on the Web Interface and it runs !!
Hope this will not happen for the next snapshots.

@tatanas Let me ask why are you renaming the host in the windows UI? Do you not know the actual name of the system at imaging time?

Second question: are you using the fog client service at all?

@sideone said in HyperV / Win 11 /Fog:

@dejv Ah, came here to say secure boot! Nice one.

Thanks @Tom-Elliott and @sideone for your replies 🙂
