Type 1 hypervisor question

I am having trouble understa.ding how a type 1 hypervisor is a virtual machine. If it loads before the boot OS, how is it not simply acting as a partition? I have installed a separate OS in a partition and on a Bootable flash drive. I have experience using virtualbox (type2) where you install the OS on top of the boot OS. This makes sense to me bc you run it on allocated system partitions on top of windows. But a type one is installed before your boot OS, which does not seem to be a VM but a separate Bootable OS still using your own hardware. What am I missing?.

You are missing that a hypervisor is NOT a VM. It is a hypervisor. Like you said yourself. It is essentially an OS that allows you to load other virtual OS's (VM's) onto it.

You’re over complicating this. 
 

A type 1 hypervisor is simply an operating system which is intended to host VM’s. Proxmox is a type 1 hypervisor. Proxmox runs bare metal. 
 

Proxmox is *basically* just Debian and some fancy webUI features for Linux KVM virtualization. 
 

Once proxmox is installed and up and running, you instal VM’s under proxmox. 
 

A type 2 hypervisor is simply a program you instal on an already running OS… like you can instal virtual box on top of windows. Windows in this instance is not the hypervisor, but you have installed an application under it that is hosting VM’s. Windows is installed bare metal, and within windows you have installed an application (virtual box) which is then hosting VM’s.
