I am trying to install Proxmox VE on an dl380G7 server by a flash card on a internal usb . Asoon as i choose to install Proxmox VE graphical i get a
message output is not supported on my vga screen.
Any ideas what I forget.
Don't install PVE to pen drives or SD cards. It does a lot of small writes to the root filesystem and will kill them quite fast, which is why an HDD as the system disk is the minimum hardware requirement (but a SSD would work too).
