Hello everyone,

I am a college student getting my hands dirty in proxmox, my college has a drive tray where I can insert a hard drive (I am using a 480GB ssd).

A problem that I encountered in ubuntu/centos/debian as well as proxmox was that my efi boot order gets messed up every time I move to another machine. In the previous operating systems I could boot with the install usb and fix the efi boot order (add the OS back to efi boot loader and then put it first in the order). The proxmox install however does not have this option I noticed, so I am trying to find out if there is a way to fix this issue permanently or if there is some kind of recovery operation I can do to fix this issue every time I change to another computer.

As an alternative I would like to ask if I put this SSD in a USB 3.0 enclosure and install proxmox directly to the USB 3.0 enclosure would I receive a massive hit in performance vs sata 3.0?

you can still boot another live-cd (e.g. ubuntu) and use 'efibootmgr' to do this

What about disabling all of the boot entries except the required one? This should be working fine even though it's more like a temporary solution.
