This is my short log about (re)starting booting machines.

configuration.yaml

    mac: ec:be:5f:ee:11:78

#SHELL command to remote start reboot2windows script (multiboot machine)
shell_command:
    ssh_reboottowindows: ssh -i /config/ssh/id_ed25519 -o 'StrictHostKeyChecking=no' root@192.168.1.2 '/root/reboot2windows'
shell_command:
    ssh_haltlinux: ssh -i /config/ssh/id_ed25519 -o 'StrictHostKeyChecking=no' root@192.168.1.2 'halt -p'

reboot2windows linux script (on the remote server)

#!/bin/bash

WINDOWS_TITLE=`grep -i "^menuentry 'Windows" /boot/grub/grub.cfg|head -n 1|cut -d"'" -f2`
grub-reboot "$WINDOWS_TITLE"
reboot
