error: file not found.
Loading linux 4.2.8.1-pve ...
loading initial ramdisk ....

after a couple of second it go further
 
I think text is a lot easier for reading log files.

I took a quick look [ busy here ] and saw that networking is not set up. so let get that fixed first if possible.

another question - what was the original operating system installed?
 
Thanks for your Feedback
Network should be allright - apt-get update und upgrade still working ping to 8.8.8.8 is working to. But will check it this evening too.

I installed from a Proxmox ISO file, the only Things i added is virtuel Switch, munin Client and the SW for watching the UPS attached over USB.
i have done all regulary updates and Upgrades for safty/Security, but did not allways rebootet the Host, sometimes in the Proxmox GUI if told to do i did..
 
Your new journal output still shows the same problems - please check where the failing mount comes from (have you looked at /etc/fstab ?) and check your network setup for references to the non-existing snippets.
