PROXMOX not starting anymore

[ppreininger]

Hi,
I did some backups and ran some updates and after the restart of my installation (4.4), no login or whatsoever is possible anymore.

I can only post a screenshot - as nothing is possible anymore. Is there something I can try or is my installation lost?

It is no big deal anymore for me, as I reinstalled Proxmox with all of my backups on another disk.

In fact, I still have a small problem regarding one virtual machine. I have no backup for this machine and copied the disk from the volume. It is a windows machine. I also managed to import the disk into my new machine. My problem is now, that the windows activation is gone - I suppose some UUIDs were changed and that's why I'm having the activatione troubles. Is there a way to access the UUIDs on my old disk and "transfer" it to my new installation?

maybe the update did not complete successfully leaving some packages in a broken state ?
is it possible to ping the machine or login via ssh ?

I would advise the following:
* at the grub prompt, right after the bios try to boot a different kernel
* if that does not help, boot the system with a live CD (ubuntu)
* inspect the content of your disks with lsblk, it should give you a hint on which partitition is your Proxmox VE installation
* when the live CD is booted, chroot into the installed system following the instructions from
https://aaronbonner.io/post/21103731114/chroot-into-a-broken-linux-install
* once the chroot is ready, try the following and post their output if something looks wrong

dpkg --configure -a
apt-get install -f

Probably windows noticed the virtualized hardware changed, so you need to reactivate (windows is *very* picky about hardware changes) IIRC it is only a matter of calling an automatic voice machine to reactivate. Or you can try to configure the VM with exactly the same settings as it was before, but I am not sure it will be enough.
