+
+## Overview
+
+Complete walkthrough for installing Proxmox VE 8.x on bare metal and preparing it for VM/LXC workloads — without helper scripts. All commands manually applied so you understand what's happening under the hood.
+
+**Source:** [YouTube — ProHomelab](https://www.youtube.com/watch?v=Tc-pjSD9uw8) | [GitHub commands repo](https://github.com/stilicho2011/ubuntu_rep/tree/main/proxmox%20iommu%20enabling%20and%20pci(e)%20passthrough/HDD%20passing)
+
+---
+
+## 1. Creating the Boot USB
+
+- Use **Balena Etcher** — more reliable than Ventoy/Rufus for Proxmox ISOs (early 8.x had boot issues with those)
+- NVIDIA GPU on the host may cause graphical glitches during install — switch to **Terminal UI** mode if needed
+- If no IP is auto-assigned via DHCP, set it manually in the network step
+
+---
+
+## 2. Installation
+
+- **Filesystem:** Choose **ext4** for beginners; **ZFS** only if you need clustering/replication and understand its RAM usage behaviour
+  - ZFS uses RAM aggressively by design (not a "leak") — it's fast because of this
+  - ZFS can also wear out SSDs faster without tuning (write amplification)
+- Set root password + any email (can be fake) during install
+- Default gateway = your router IP; DNS = router IP or preferred resolver
+- Access UI after reboot at `https://<IP>:8006`
+
+---
+
+## 3. Repository Switching (free tier)
+
+Proxmox ships pointed at the paid **Enterprise** repo. Switch to the free **no-subscription** repo:
+
+### Via UI
+`Node → Updates → Repositories` — disable enterprise, add no-subscription
+
+### Via SSH / Shell
+
+```bash
+# Check DNS is correct
+nano /etc/resolv.conf
+
+# Add no-subscription + security repos
+nano /etc/apt/sources.list
+# Add:
+# deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription
+# deb http://security.debian.org bookworm-security main contrib
+
+# Disable enterprise repo
+nano /etc/apt/sources.list.d/pve-enterprise.list
+# Comment out the deb line
+
+# Disable Ceph enterprise repo (not needed without cluster)
+nano /etc/apt/sources.list.d/ceph.list
+# Comment out the Enterprise line
+
+# Update + upgrade
+apt update && apt upgrade -y
+
+# Reboot after significant kernel updates
+reboot
+```
+
+---
+
+## 4. IOMMU / PCI Passthrough Preparation
+
+Required to pass physical devices (GPU, HBA, NIC) into VMs in full isolation.
+
+### Step 1 — Enable IOMMU in GRUB
+
+```bash
+nano /etc/default/grub
+```
+
+Find `GRUB_CMDLINE_LINUX_DEFAULT` and append:
+
+| CPU vendor | Value to add |
+|-----------|-------------|
+| AMD | `amd_iommu=on iommu=pt` |
+| Intel | `intel_iommu=on iommu=pt` |
+
+> `iommu=pt` (passthrough mode) is optional for AMD but harmless to include.
+
+Update bootloader:
+```bash
+update-grub
+```
+
+### Step 2 — Load IOMMU kernel modules
+
+```bash
+nano /etc/modules
+```
+
+Add (Linux kernel ≥ 6.2 — **3 modules only**, not 4):
+```
+vfio
+vfio_iommu_type1
+vfio_pci
+```
+
+```bash
+update-initramfs -u -k all
+reboot
+```
+
+### Step 3 — Verify IOMMU is active
+
+```bash
+dmesg | grep -e DMAR -e IOMMU
+```
+
+Look for: **`Interrupt remapping enabled`** — confirms IOMMU groups are active.
+
+---
+
+## 5. Disable Subscription Nag Popup
+
+The popup appears on every login without an Enterprise subscription. Remove it:
+
+```bash
+# One-liner (see GitHub repo for exact command)
+sed -Ezi.bak "s/(Ext.Msg.show\(\{.*?title: gettext\('No valid sub)/void\(\{ \/\/\1/g" \
+  /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js
+systemctl restart pveproxy
+```
+
+Verify by opening a fresh private/incognito browser session — popup should be gone.
+
+---
+
+## 6. Storage Overview (defaults)
+
+| Store | Purpose |
+|-------|---------|
+| `local` | ISO images, CT templates, backups |
+| `local-lvm` | VM disks, CT volumes (LVM thin) |
+
+---
+
+## Key Takeaways
+
+- **Balena Etcher** is the safest USB writer for Proxmox ISOs
+- **ext4** for beginners, **ZFS** only if you know what you're doing (RAM usage + SSD wear)
+- Always switch from enterprise → **no-subscription** repos right after install
+- **IOMMU** must be enabled in GRUB + kernel modules loaded before GPU/HBA passthrough works
+- Kernel ≥ 6.2 needs only **3 vfio modules** (not 4 as in older guides)
+- The subscription nag popup is cosmetic only — one sed command removes it
+- Ceph repo can be disabled if you're not running a cluster
