Cannot reboot system
 

Greetings, is there anyway to fix this issue? Thanks

root@win10-64bit:/# reboot
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
Failed to talk to init daemon.
root@win10-64bit:/#

It says it is already down.

Did you by any chance interrupt the boot or get a prompt to enter root password to go to command prompt (i.e. single user or something less)?

If you type "exit" does it do anything?

Does halt or "reboot -f" do anything?

Failing all else you could try physically power cycling the system (or if its a VM use the VM console to do the equivalent).

Your hostname is a bit confusing.

But the problem is that systemd is not running. The reboot command works by communicating with PID 1 via the DBUS. It looks like you launched your kernel with an alternative init, such as init=/bin/bash. If so, I believe the only way to reboot is to simply switch it off, or to exit the shell, which results in a panic. Then switch it back on.

Are you using WSL (Windows Subsystem for Linux)?
