Thank you for very fast and great support! (I made a small donation )
I hope that my BIOS problem will be resolved too.

I re-installed fog and everything works fine!

[quote=“Tom Elliott, post: 29862, member: 7271”]When you’re building the images, boot into a debug task when you’re ready to upload. Run fixparts /dev/sda and it should verify that everything is set properly for your system.

Then, once complete, if you create a debug - upload tasking, once complete you just type fog and you’re uploading.[/quote]

This way I fixed this problem, thank you!!

OK I changed the repositories to strech, updated and now version of dnsmasq is 2.76.

As I said everything works great! Thank you again for great support!

And everything works!! Thank you for help!

At he time I have a multiboot PC: Windows 11, Gentoo, Linux From Scratch.
I tried to experiment with fog, so I installed it on an old Intel NUC with 256GB disk space and debian 12 which is no enough even to capture my smallest OS LFS. How much disk space do I need to store the images? Would you suggest to extend this NUC or get another PC?

OK I changed the repositories to strech, updated and now version of dnsmasq is 2.76.

I edited /etc/apt/sources.list and added
deb http://ftp.de.debian.org/debian testing main
then

apt-get update
and then
apt-get install dnsmasq/testing

~$ sudo apt-get install dnsmasq-base/testing

How can I get rid of 2.72? Why windows xp pc boots normal but then goes to windows instead of capturing image?

~$ dpkg -l | grep dnsmasq

I just followed this guide: https://forums.fogproject.org/topic/12796/installing-dnsmasq-on-your-fog-server
. The only thing I put is the IP of the server where needed.

Thank you!

Thank you, I installed dnsmasq on Debian 8. Version was 2.72 by default and then I installed successfully as the terminal said version 2.80-1. But with
sudo dnsmasq -v it still says verson 2.72 is installed, I guess because version 2.80-1 is from testing repository.

Unpacking dnsmasq (2.80-1) ...
Setting up dnsmasq (2.80-1) ...
[ ok ] Starting DNS forwarder and DHCP server: dnsmasq.
hk@debian-server:~$ sudo dnsmasq -v
Dnsmasq version 2.72

This massage about 2.72 version shows even if I uninstall dnsmasq.

I still have the router as DHCP server.
When I create and execute an instant Capture task, Windows XP pc boots but shows message:
TFTP.
PXE-T01: File not found
PXE-E3B: TFTP Error - File not found
PXE-M0F: Exiting PXE ROM.
and then boots to windows.

I use the same FOG installation as I had with dd-wrt router and dnsmasq in router.

Any help?
Thank you!

I have 2 PCs (1 windows 10, 1 windows xp) connected on a LAN to a FRITZ!Box 7590 router. I Can I use fog to take images from my PCs with this router? Can I put pxe boot options in settings of this router?
Thank you!

As I said everything works great! Thank you again for great support!

I re-installed fog and everything works fine!
