3. Verify the SHA256 checksum of the file

Step 2: Create a bootable USB stick

Step 3: Run the installation

1. Select Install Proxmox VE in the boot menu
2. Choose the target disk (ext4 or ZFS)
3. Set country, timezone and keyboard layout
4. Set root password and email address
5. Enter hostname and static network configuration
6. Start the installation and reboot after completion

Step 4: Open the web interface

After reboot, access the web interface at:

Log in with root and your password (Realm: Linux PAM).

Step 5: Adjust repository (no-subscription)

If you don't use an enterprise subscription, disable the enterprise repository and use the no-subscription repo:

sed -i 's/^deb/#deb/' /etc/apt/sources.list.d/pve-enterprise.list
apt update && apt full-upgrade -y
