ive used this script yesterday for my new node. Work Perfectly. Are you sure thats the problem? I think maybe the update to debian12.9?

I mean I didn't change anything on Proxmox, but the issue template forces me to chose one. The causality is very direct. I ran this script with all defaults, it doesn't boot anymore,  and now I'm trying to recover my installation somehow.

I also just run it on 3 of my nodes without any issue.

Running fine for me too.

I hardly believe the update script messed up proxmox so bad that it does not boot anymore.
I suggest looking into syslog dmesg etc and post on proxmox forums if necessary.

Edit: Didn't meant this to sound that rude in any way, english is not my primary language.

That's a pretty rude thing to respond. Maybe reconsider how you approach others, who have tried to contribute to the scripts here and are reporting a pretty egregious failure mode after running one of your scripts.

Here's the order of events:

1. I ran the script
2. Proxmox started acting funny
3. I rebooted
4. It doesn't find a boot disk

If I threw a cheeky rm -rf / --no-prese-root in there, I'd probably refrain from posting here :)

Not the first time I used this script. I thought it would be important to document the failure.

I have received better support from strangers on Threads than this "community", which is a bit worrying.
Anyone else that runs into a "Can't find bootdisk", I was sent to this page: https://pve.proxmox.com/wiki/Recover_From_Grub_Failure
I will try this on the weekend and hope for the best.

I will close this now, as I don't need more contributors to inform me that it worked for them.

I might have written you exactly the same page, but I assume it has nothing to do with the update_os. Since it doesn't do anything to the main node or anything else. It looks more like a failed kernel that killed the grub.

But it's nice if others can help you ;-)

Cool ;-)
