@JCS-RVK Okay so I don’t see why this kernel wouldn’t work for you with those settings. Only difference I can think of may be the initrd version that is being loaded. I know that @BPSTravis is using the latest released version so it wouldn’t hurt to update yours too.

I also see that you are running an older version of FOG. You could upgrade to the latest stable release and that will also download the latest initrd.

You could also download it manually if you don’t want to update FOG:

On your FOG server, run this command to download the latest initrd
wget https://github.com/FOGProject/fos/releases/download/20260306/init.xz

Move it to the correct location like this:
sudo mv init.xz /var/www/fog/service/ipxe/

Then you need to change the permissions and ownership of that file:
sudo chmod 644 /var/www/fog/service/ipxe/init.xz

Red Had based server: sudo chown fogproject:apache /var/www/fog/service/ipxe/init.xz

Debian based server: sudo chown fogproject:www-data /var/www/fog/service/ipxe/init.xz

@Tom-Elliott
I did not update yet to 1824, but i did SELECT * FROM HISTORY;

MariaDB [fog]> SELECT * FROM history; +-----+----------------------------------------------------------------------------------------+-------+---------------------+-------------+ | hID | hText | hUser | hTime | hIP | +-----+----------------------------------------------------------------------------------------+-------+---------------------+-------------+ | 1 | [2026-04-01 08:33:55] MulticastSession ID: 1 NAME: test has been successfully updated. | fog | 2026-04-01 08:33:55 | 10.10.3.116 | +-----+----------------------------------------------------------------------------------------+-------+---------------------+-------------+ 1 row in set (0.000 sec)

the new session i create are not shown, and dont work until i run the maintenance queries

then it shows in history table:

MariaDB [fog]> SELECT * FROM history; +-----+----------------------------------------------------------------------------------------+-------+---------------------+-------------+ | hID | hText | hUser | hTime | hIP | +-----+----------------------------------------------------------------------------------------+-------+---------------------+-------------+ | 1 | [2026-04-01 08:33:55] MulticastSession ID: 1 NAME: test has been successfully updated. | fog | 2026-04-01 08:33:55 | 10.10.3.116 | | 2 | [2026-04-01 09:10:37] MulticastSession ID: 1 NAME: test has been successfully updated. | fog | 2026-04-01 09:10:37 | 10.10.3.116 | +-----+----------------------------------------------------------------------------------------+-------+---------------------+-------------+ 2 rows in set (0.000 sec)

@heix75 Thanks a lot for reply!
I use a medical lab program that stores clients data and examinations results almost all day. Of course I take incremental SQL backups.
So if something breaks I would like to have a recent PC backup to only restore SQL.
I used Macrium for that and now I use UrBackup which is open source but not widely used and I wonder if Fog would be a better solution.

@Tom-Elliott Hi Tom,

Have you sysprep your Windows before capture ? (i don’t think it’s related but it’s important to do this, if no need nothing just launch C:\Windows\System32\Sysprep\sysprep.exe and coche generalize, shutdown)

I use “Multiple Partition Image All Disks” just for the upload, and after upload done, i set “single disk resizable” for the deploy.

@lucasgfaj have you turned off secure boot?

@trent_potter Yes you figured it out. Sysprep is a Windows utility, it has nothing to do with FOG. It is always recommended to sysprep before capturing an image.

@devle I’ve made a couple of edits, though I still cannot replicate the problem you’re seeing.

You shouldn’t see the errors any more (just saying), though I don’t know if these things will fix whatever problem you’re seeing.

@KMEH Hi,

I tried your method and it only partially worked. It reached the FOG menu correctly after enrolling the key, but the problem arises when I try to perform a quickreg or deploy an image. In both cases, I get the following error (it starts working again when I disable Secure Boot)fog uefi error.png

my version is 1.5.10

Hello @jrajra,
I got this to work on my instance using ShredOS by doing the following:

Log in to your Fog web portal Go to “Fog Configuration” Click the “iPXE New Menu Entry” button Enter the following details:
* Menu Item=ShredOS
* Description=Boot and Shred (AutoNuke)
* Menu Show with=Not Registered Hosts
* Parameters= kernel https://${fog-ip}/shredos/boot/shredos console=tty3 loglevel=3 shredos_exclude_boot_disc="yes" nwipe_options="--autonuke --nowait --method=zero --noblank --nousb --PDFreportpath=noPDF --autopoweroff" boot Log into your Fog Linux server Open the terminal Run the following commands: mkdir /iso mkdir /var/www/html/shredos wget -O /iso/ShredOS.iso https://github.com/PartialVolume/shredos.x86_64/releases/download/v2025.11_28_x86-64_0.40/shredos-2025.11_28_x86-64_v0.40_20260204.iso sudo mount -t iso9660 -o loop /iso/ShreadOS.iso /var/www/html/shredos chmod -R 777 /var/www/html/shredos

Doing these steps should create a “New Menu Entry” for ShreadOS and specify to shred upon boot, don’t write a completion file, & then turn off the device. (For safety in our environment, I have this option only appear if the device is not registered.)
It then downloaded the ShreadOS file from Github & then mounted the iso as an accessible boot file in the Fog URL. (You can manually download the file & put it in the “/iso” folder instead if you want.)

I have tried this with dban as well, but that only worked for old BIOS based computers. This one on the other hand works for UEFI computers.
I also found this article that might help you: https://forums.fogproject.org/topic/10944/using-fog-to-pxe-boot-into-your-favorite-installer-images
I hope this helps you,
