@Sebastian-Roth it look like its not writhing anything to the logs

@Wayne-Workman look what i wrote

i am using ubuntu server 16.5 i think
after restart i got this error :
Unexpected inconsistency: Run fsck manually
something like this and i fount the command to do the fsck that needed .

after that the fog server came up as usual but…

pxe booting gotes to the white screen of the menu and i got an error.
in the settings under “iPXE Menu Item Settings”

i dont have anything its empty.

and i dont have any backup

hello my server crushed on ubuntu and after i fix it
pxe stopped working

in the fog settings under “iPXE Menu Item Settings” i have nothing its blank

anyone knows how can i fix it?

hello is fog server using the regular pxe ? or it is using ipxe to boot images?
