@gwhitfield The portfast it’s enabled in all ports of the switch so at this moment i dont know what to do anymore. Thanks for all that helped me.

@Tom-Elliott

I changed the boot file to ipxe.pxe and i’ve got the same original problem.

So i downloaded the boot file ipxe.pxe using this command:

wget https://svn.code.sf.net/p/freeghost/code/trunk/packages/tftp/ipxe.pxe -O /tftpboot/ipxe.pxe

And the result was the same as using undionly.kpxe, stops at IPXE.

@Tom-Elliott

Now i’m using undionly.kpxe. I tried undionly.kkpxe but it did not work.
I will try ipxe.pxe.
This occurs in all machines.

Thanks

@Tom-Elliott

Fog stops in IPXE even when i just want to get to the menu.

@Tom-Elliott

I still don’t understand why computer reboots with the original undionly.kpxe that comes with the fog installer (1.2.0) and when i get the undionly.kpxe from https://svn.code.sf.net/p/freeghost/code/trunk/packages/tftp/undionly.kpxe
it works but i have to write exit in IPXE.
You can see it in this photo:

I will try to do spanning tree /port fast setting on the switch like @Sebastian-Roth said but i think this is not the reason.
Is there any script that i can do to automatically exit from IPXE?
Thanks

@Wayne-Workman

Today I installed another server with the same configurations and i noticed that the original problem was solved by getting another undionly.kpxe.

wget https://svn.code.sf.net/p/freeghost/code/trunk/packages/tftp/undionly.kpxe -O /tftpboot/undionly.kpxe

I originally thought that the problem was solved by upgrading the Kernel and changing the permissions of ipxe, but the problem was solved by getting another undionly.kpxe. But I don´t know if this boot file is reliable.

The only thing i know, is that after this, if i write exit in ipxe, the fog works. But i need to solve this.

The contents of boot.php that you asked (http://10.1.8.1/fog/service/ipxe/boot.php) are:

@Tom-Elliott

I Tom. I had to change the boot file again to undionly.kpxe.
At this time i don’t know how i solved this problem.
I tried two things:
I updated the kernel to version 3.19.3 and I changed permissions of ipxe:

         chmod -R 775 /var/www/html/fog/service/ipxe

The only problem is that i have write exit in ipxe to download/upload start.

Many Thanks

@Wayne-Workman

I changed the boot file to undionly.kkpxe and now it works but i have write exit in IPXE.
Do you know you to work around this?
