I want to test Proxmox and I want to install Proxmox not on the whole disk but on a partition. How do I mount the whole thing as root so that Proxmox is installed only on one partition and does not delete the whole disk?
 
I don't think that the Proxmox installer supports that. You could first install Debian (where you can setup/choose the partitions in their installer) and install Proxmox on top of it.

EDIT: Alternatively, install Proxmox within a VM (like VirtualBox or VMWare) on a smaller disk. Copy that virtual disk to a physical partition and fixup the boot process manually. That's how I install new versions of Proxmox: by installing it first on ZFS whitin a VM inside Proxmox and then mirror the ZFS pool to a real drive partition.

@leesteken this is an interesting approach.
How do you copy the virtual disk to the physical partition? do you use clonezilla or similar software?

Thank you,

I passthrough a physical drive and add that as a mirror of the virtual ZFS pool (with ESP) inside the VM. Then I transport that half of the mirror to another system (and fix the bootloader).
