Node pm2 Autoboot Node palette missing unable to reinstall

[PainWorry]

My friend have just install pm2 to make node-red automaticaly start when it boot up
https://nodered.org/docs/faq/starting-node-red-on-boot#2-determine-the-exact-location-of-the-node-red-command
but then he've found that node palette is missing and unable to reinstall how can I fix it.

Your friend imported a flow that contains nodes that are not installed, in this case, node-red-dashboard and
a serialport node (don't know which one)

To fix it, either remove the nodes from the flows and deploy, or install them, via the hamburger menu > palette, install tab, search > install or manually;

cd ~/.node-red
npm install <node name>

Solve
Starting Node-RED on boot : Node-RED
sudo npm uninstall -g pm2
I'm able to use the flow again but have to find another way to autoboot

You solved it by uninstalling node-red? How can node red run at all if you have uninstalled it?

[PainWorry]

sorry I write it wrong
sudo npm uninstall -g pm2

@PainWorry

have to find another way to autoboot

The docs have a section on running node-red on startup in windows.
