Step-by-Step Tutorial

Step 1: Prepare the Installation Media

1. Download the Proxmox ISO: Visit the official Proxmox website and navigate to the download section. Select the latest version of Proxmox VE and download the ISO file to your computer.
2. Verify the ISO checksum: To ensure the integrity of the downloaded file, verify the checksum. Use the following command in your terminal:

   sha256sum /path/to/downloaded/proxmox.iso

   Compare the output with the checksum provided on the Proxmox website.

3. Create a bootable USB drive: Use a tool like Rufus (for Windows) or Etcher (for macOS/Linux) to create a bootable USB drive. Insert your USB drive and open the tool. Select the downloaded ISO file and the USB drive, then start the process.
4. Ensure the USB drive is empty: Before starting the creation process, make sure that the USB drive does not contain any important data, as this process will erase all data on it.

Expected outcome: You will have a bootable USB drive containing the Proxmox installation files. For faster installation, it is recommended to use a USB 3.0 drive.

Troubleshooting & Verification

Ensure the installation media is correctly created using tools like Rufus or Etcher. Verify the integrity of the downloaded Proxmox ISO by checking the SHA256 checksum. Additionally, confirm that the BIOS settings are configured to boot from the USB drive.

Step 2: Access BIOS Settings

1. Restart your Dell Mini PC.
2. As soon as the Dell logo appears on the screen, repeatedly press the F2 key. This action will allow you to enter the BIOS setup.
3. Once in the BIOS setup, use the arrow keys on your keyboard to navigate through the menu options.
4. Locate the «Boot» menu, which is essential for configuring the boot order for Proxmox installation.
5. If the F2 key does not work, refer to the Dell Mini PC manual for the correct key to access BIOS settings.

Be cautious when navigating the BIOS. Avoid changing settings unless you are certain of their function, as this could affect your system’s performance or boot capabilities.

Troubleshooting & Verification

Ensure your Dell Mini PC is powered off before attempting to access the BIOS. If you cannot enter the BIOS, try different key combinations such as F2, Delete, or Esc during startup. Verify that your keyboard is functioning properly and connected securely.

Step 3: Change Boot Order

1. Restart your Dell Mini PC and immediately press the appropriate key to enter the BIOS setup. This key is usually F2 or Delete, but it may vary by model.
2. Once in the BIOS menu, navigate to the «Boot» tab using the arrow keys on your keyboard.
3. Locate the «Boot Order» or «Boot Priority» section. Here, you will see a list of devices that your system can boot from.
4. Select the USB drive from the list. You may need to use the +/- keys or follow on-screen instructions to move the USB drive to the top of the list, making it the first boot device.
5. After adjusting the boot order, look for the ‘Save and Exit’ option, usually found in the Exit menu. Select it to save your changes.
6. Confirm any prompts to save the changes and exit the BIOS.

Upon the next restart, your system should boot from the USB drive. Remember to write down the original boot order in case you need to revert the changes later. If you have other bootable devices, ensure they are set lower in the boot order to avoid conflicts.

Troubleshooting & Verification

Ensure that the boot order is set correctly in the BIOS, prioritizing the USB drive or installation media. After saving changes, restart the system. If Proxmox does not load, recheck connections and try a different USB port or installation media.

Step 4: Start Proxmox Installer

1. After saving the BIOS settings, allow the system to reboot. Ensure that the USB drive containing the Proxmox installer is still connected.
2. Watch for the boot menu to appear. You may need to press a specific key (often F12 or Esc) to select the boot device if it does not automatically boot from the USB drive.
3. Once the Proxmox installer begins, you will see the Proxmox Virtual Environment installation interface on your screen. Follow the on-screen prompts carefully.
4. Select the appropriate options for your installation, including the target hard disk and any additional configurations.
5. Proceed with the installation by confirming your selections. The installation process will begin, and it is crucial not to interrupt it.

Tip: For better stability during installation, use a wired connection. Always have a backup of any important data before proceeding. Warning: Do not interrupt the installation process once it starts.

Troubleshooting & Verification

If the Proxmox installer fails to start, verify that the bootable USB is correctly created and formatted. Check BIOS settings to ensure UEFI or Legacy mode is set according to your installation media. Ensure secure boot is disabled and hardware compatibility is confirmed.

Step 5: Select Installation Target

1. Once you reach the installation screen, you will see a list of available drives.
2. Carefully review the list to identify the correct hard drive where you want to install Proxmox. This is crucial to prevent any accidental data loss.
