Welcome to GRUB" after GUI update

[Smvb64]

Hello all,

Looking for some troubleshooting steps, I performed an update from the Proxmox GUI.
After restarting, I am now stuck on a "Welcome to Grub" Screen and unable to type.

I am running Proxmox 8 (Upgraded from 7 to 8 a few months ago)
Unfortunately, this is all the information I have.

Please let me know if it possible to retrieve logs or if there are any recovery disks I might be able to use in this situation.

UPDATE:
Looking at this thread https://forum.proxmox.com/threads/welcome-to-grub-after-apt-dist-upgrade.162989/
I decided to check my BIOS settings as well and saw this






Just like the thread, I set Proxmox as primary and booted.
Looks like I may have jumped the gun - the thread I linked about is the same issue I am having. Is there any else that needs to be done?

I am getting a new error though




Thank you guys
Dan

if booting the "proxmox" entry works, please follow the instructions printed during the upgrade to also include the removable bootloader entry in future upgrades. I don't think the other error is related - where exactly do you see it?

Hello, thank you for your reply.

I followed the instructions and this is what I got:

It looks like it worked correctly from what I'm seeing in the other thread

Regarding the other error, that is coming from my Plex installation



This is coming from my Plex LXC - It is a different issue but worked before I did the update and rebooted.
I may need to make a separate thread on this one

Best,
Dan

yes, that sounds like a different problem!
