Hello this is probably a dumb question but I'm having trouble understanding how to do this. I have an Ubuntu server VM that I accidentally gave 3000GB of space instead of 300GB and the partition I'm trying to shrink inside the VM is an LVM that's part of the root file system so I can't unmount it. From what I've researched, the solution to this first step of the process is to boot the VM through a normal Ubuntu iSO (not Ubuntu server ISO) and resize it using the tools available in there. Problem is that I have no idea how to boot it like that from the Proxmox interface since I've only used it once to set up a VM and that was it. I've uploaded the ISO in there and I made a snapshot and clone of the VM I'll be doing this to so I'm not worried about accidentally messing up and corrupting everything. If someone can please help me understand what I'm supposed to click on in the Proxmox interface I'd greatly appreciate it. I'm on the latest version which is version 9.2.3 if that's necessary info
