I moved your post to the User Support category @smlt, because it seemed more adequate to me. Please feel free to move it back if you disagree :slightly_smiling_face:

Do you mean the Qubes system itself?
Which version of Qubes are you running?
Do you see any error messages before the “reboot parameter file”
message?

im running r4.0

And do you mean the Qubes system?

yes qubes 4.0

yes but it freeze on this and dont reboot

@deeplow Thanks for that detail - it’s much appreciated.
That warning is (I think) spurious and fixed in current systemd - it’s a
consequence here of an older dom0.
It doesnt explain the failure to reboot: on that, I have no idea.
