Making a Bootable USB Disk for Proxmox Installation
After the ISO file has been prepared, the next step in the installation of Proxmox VE is the creation of a bootable USB disk. To do this, we have the option of using Rufus, Etcher, or the command-line utility dd, depending on the operating system we are using.
Before we start, it is important to understand that the USB disk will be wiped clean. It is therefore recommended that we use a reliable USB disk, preferably one with a capacity of at least 2 GB. Once the ISO file has been written onto the disk, we should safely eject the disk and connect it to the target server.
Installing Proxmox VE on a Physical Server
This section describes the complete and technical procedure for installing Proxmox Virtual Environment (Proxmox VE) on a bare-metal server. Each phase of the installation is separated for clarity and operational accuracy.
1. Booting the Server from Installation Media
Insert the Proxmox VE installation USB drive into the server and power it on.
Enter the server’s BIOS/UEFI settings if necessary and configure the boot order to prioritize the USB device.
Once the Proxmox boot menu appears, select:
Install Proxmox VE
This option initiates the graphical installer for a fresh installation on the physical host.
2. License Agreement Acceptance
The installer first presents the Proxmox VE End User License Agreement (EULA).
Carefully review the terms and select Accept to proceed.
The installation cannot continue unless the license agreement is accepted.
3. Target Disk and Filesystem Configuration
In diesem Stadium, you must select the disk on which Proxmox VE will be installed.
Key considerations:
- All existing data on the selected disk will be permanently erased
- Ensure the correct physical drive is chosen, especially on systems with multiple disks
- You may also configure advanced storage options, einschließlich:
- Filesystem type (Z.B., ext4, XFS, or ZFS)
- RAID configuration (if ZFS is selected)
- Disk cache and compression settings (for advanced deployments)
This step directly impacts system performance, Redundanz, and storage behavior.
4. Regional and Localization Settings
Configure system localization parameters to ensure correct timekeeping and input behavior:
- Country
- Time Zone
- Keyboard Layout
These settings are critical for accurate logging, Terminplanung, and administrative access.
5. Root Account and Administrative Access Configuration
Set the root password for the Proxmox host.
This account will have full administrative privileges over the hypervisor, virtual machines, and containers.
Zusätzlich, provide an email address for system notifications such as:
- Backup failures
- Disk or hardware issues
- Cluster and replication alerts
Use a strong, secure password to protect the management interface.
6. Network Configuration
Define the primary network settings for the Proxmox management interface:
Hostname (Fully Qualified Domain Name recommended)
Management IP Address
Subnet Mask
Default Gateway
DNS Server(s)
A static IP address is strongly recommended, as Proxmox relies on consistent network identity for:
- Web management access
- Cluster communication
- Storage and backup connectivity
7. Installation Execution and System Deployment
After reviewing and confirming all configuration parameters, the installer begins:
