@george1421 Managed to get it fixed.
I followed these insturctions and found out that I had the 066 was not selected 
https://wiki.fogproject.org/wiki/index.php?title=BIOS_and_UEFI_Co-Existence
thanks a lot for the help and keep up the good work.
Wishing a great Christmas and New year to all the team, and to your families and loves ones!
@george1421 I am on leave and will be back on wed to try it out.
@george1421 Basically I went into the server room and connected the laptop to the server switch (which gives ip on the same network as the fog server and the vm)
However it is not booting into the fog menu, it is booting into the dell diagnostics
I think the issue is that it is opening the file undionly.kpxe instead of ipxe.efi?
@george1421 first of all thanks for your help :):):)
-The policy on the dhcp is enabled on the dhcp of the pcs
-Booting UEFI with a real computer
I have a dell laptop and after changing from raidon to ahci I managed to boot into the fog menu, registered the machine.
The fog server and the laptops are on a different subnet. However the fog server and the vmware I have issues booting from network are on same subnet
@george1421 first time, I had arch 7 configured (probably was a few years ago when I configured fog but I dont recall I have used uefi up till now) I have now added arch 9
I am getting the error on first start booting from network and also when selecting to boot from
When it starts on boot from network I am getting
If I select to boot from efi network it says start pxe over ipv4 and then goes into the boot menu again
I am trying to create an image on my vmware server
however when I am trying to boot from network so that I can take an aimage to my fog server I am encountering an issue
With bios I could manage to take images however newer laptop dont have legacy options and I am starting to have issues.
I have a vmserver and I store my images on the server so that when I need an updated image I just open it, run the updates or do any modifications needed and then run sysprep and backup it using fog.
I am now trying to take an image with UEFI and when I am trying to boot using network however when I seleft efi network it displays start pxe over ipv4 and then goes back to the boot menu
Any ideas what I need to do to fix my issue
was there a fix for this issue or we still need to change to ahci?
@sebastian-roth you have a point there a good way to learn linux 
@george1421 I guess its better to just stop doing the OS updates.
I am a bit OCD about the updates
@george1421 seem that after a couple of hours being left alone it is working again
after ubuntu updates fog server is not loading in the browser. Any ideas how to fix it? I am not sure what version I was running however was updated earlier this year
I tried downloading the latest version to /opt/ and running the ./installfog.sh command. the scrip ran and when finished displayed the ip to login however still didnt load
@tom-elliott I tested on another computer and its working.
on this particular pc its not working. I will try and uninstall fog client from the pc and reinstall it again and will see if it works.
IF it still doesnt work will try to remove from fog server and re add
@sebastian-roth said in Changing hostname from fog broken:
http://fog/fog/management/ - doesnt seem to open
http://192.168.0.58/fog/management - works
however when I ping fog I get a reply
I only got 1 fog server

I found some other files that were compressed please find above.
The php7.4 log is all the same as posted before
@sebastian-roth If I redownload Fog and reinstall it will it fix the issue? (hopefully it will keep all settings)
