Windows 7 Installer

Bootable USB Install / Repair Legacy OS

Overview

Boot this USB to install or repair Windows 7. It supports clean installs, in-place repairs (on compatible hardware), basic partitioning, and manual driver loading during setup.

Quick Start (Clean Install):

Enter your PC’s boot menu and choose the USB (try both UEFI and Legacy/CSM options if shown).
At the Windows 7 setup, pick language/keyboard → click Install now.
Accept license → choose Custom (clean install) → select the target drive/partition.
(Optional) Click Drive options to delete/create/format partitions as needed.
Proceed with installation → the PC will reboot multiple times → complete OOBE (user, time, network).

⚠️ Security note: Windows 7 is a legacy operating system. For internet-connected use, consider upgrading, isolating the device from the web, or hardening the system and keeping offline where possible.

Use Cases

Expand a scenario to view step-by-step instructions.

🆕 Clean Install (from scratch)

Back up important data from the target drive (installing will overwrite partitions if you reformat).
Boot from the USB → choose language/time/keyboard → Install now.
Pick Custom → select the destination partition or unallocated space.
Drive options → Delete ALL of the old partitions → Next (it will automatically re-create the necessary partitions).

Let setup copy files and reboot. Complete setup (user, time zone, network) when prompted.

Tip: Keep chipset/storage/network drivers on a second USB for quicker post-install setup.

🛠️ Repair Tools (Startup Repair & System Restore)

Boot from the USB → click Repair your computer (bottom-left on the first setup screen).

Select the Windows 7 installation → choose Startup Repair to fix boot issues.
Alternatively, pick System Restore to roll back to a previous restore point.
Reboot to test; if still failing, run Startup Repair again or check the disk with chkdsk /f from Command Prompt.

📦 Load Storage/USB/NVMe Drivers During Setup

When the disk list shows blank or says no drivers found, click Load driver.
Browse to a second USB containing the correct storage/USB 3.0/NVMe drivers → select → Next.
Once the disk appears, continue with the install. You can add network/GPU drivers after setup completes.

💡 On newer hardware, Windows 7 often needs USB 3.0 and storage (AHCI/NVMe/RAID) drivers injected or loaded manually.

Troubleshooting

💾 “No device drivers were found” / Keyboard & Mouse don’t work

Plug into a USB 2.0 port if available; keep a basic wired USB keyboard/mouse handy.
Click Load driver and provide USB 3.0/xHCI and storage controller drivers from a second USB.

🔐 Can’t install to GPT / “Windows cannot be installed…”

For Legacy BIOS/CSM, install to an MBR disk (convert with diskpart → clean → convert mbr).
For UEFI, install to a GPT disk (convert with diskpart → clean → convert gpt), and disable CSM.

🧿 Secure Boot / UEFI compatibility

Disable Secure Boot in firmware for Windows 7 installation.
If the USB shows twice in the boot menu, try the non-UEFI (Legacy) entry first for older hardware.

🔑 Product Key / Activation issues

Use your legitimate Windows 7 product key. OEM devices may auto-activate if the SLIC/BIOS marker is present.
If activation fails, verify edition (Home/Pro/Ultimate) matches the key and installation media.
