Win 11 Image USB Boot

• On a working Windows PC, download the Windows 11 Media Creation Tool (look for “Create Windows 11 installation media” on Microsoft’s Windows 11 download page).
• Run the downloaded executable, accept the license, choose “Create installation media (USB flash drive, DVD, or ISO file)”, then choose “USB flash drive.”
• Insert your USB stick, select it when the tool prompts, and let the tool download and create the installer. Wait until it finishes; don’t remove the USB during the process.

• Download the official Rufus program and the Windows 11 ISO from Microsoft. Open Rufus (it’s portable — no install).
• In Rufus choose your USB device, click SELECT and pick the Windows 11 ISO. Choose the partition scheme: GPT for UEFI (most modern laptops), MBR for legacy BIOS only. If you need to bypass hardware checks there’s an “Image options” choice in Rufus where you can select an Extended/unsupported install option — use only if you understand the tradeoffs. Click Start and confirm (this erases the USB).

• Power down the laptop. Insert the USB.
• Use the Lenovo Boot Menu:
  • Many Lenovos have a Novo (small recessed button or hole) you press with a paperclip when powered off to open the Novo Menu → choose Boot Menu.
  • Alternatively, repeatedly press F12, Esc, or F10 right after powering on to open the Boot Menu (key depends on model). If none work, press F2 or Enter to enter BIOS/UEFI and find Boot or Boot Order.
• From the Boot Menu select your USB device (it may appear as the USB brand or “UEFI: USB…”) and press Enter. The installer should start.

• If you only need a recovery/rescue environment (to access files, run repair tools, or restore an image), you can:
  • Use the Media Creation Tool to create the Windows installer USB and choose “Repair your computer” from the installer screens, or
  • Create a recovery drive from Windows (Settings → Recovery → Create a recovery drive) on another working PC — this makes a WinRE USB that includes recovery tools. Both approaches let you get into Troubleshoot → Advanced options.

• For modern systems choose GPT + UEFI when creating the USB (Media Creation Tool does that automatically for most PCs). If Secure Boot prevents booting from the USB, temporarily disable Secure Boot in BIOS/UEFI, boot the USB, then re-enable Secure Boot afterwards if you want.

• Confirm the USB shows in another PC (the creation completed successfully).
• Try the other Boot Menu key (Novo, F12, Esc). Some models require the Novo button to reach the menu.
• In BIOS/UEFI, check “Boot from USB” or move the USB to top of boot order temporarily.
• Recreate the USB using Rufus if the Media Creation Tool fails — Rufus gives clearer options and diagnostic messages.

• If you want to reinstall Windows: choose Install now (or Repair your computer if you only need repair/restore). If you want to run your image backup software, boot to the recovery/repair environment and use your backup tool’s rescue media or file-level restore as appropriate.

• Do you want a full installer USB (to reinstall Windows) or a recovery USB (repair and restore tools)?
• Do you want the Media Creation Tool steps with exact menu clicks, or a Rufus walkthrough (I can give step-by-step with screenshots/notes)?
• Model number of your new Lenovo (so I can confirm its exact Boot Menu key or where the Novo button is).

Download Windows 11 Disk Image (ISO) for x64 devices​

• If you want the simplest, official, automatic route: use Microsoft’s Media Creation Tool (“Create Windows 11 installation media”) — it downloads Windows 11 and writes the USB for you. This is easiest for most users.
• If you prefer to download the ISO (the page you found) because you want more control (choose GPT/UEFI vs MBR, bypass TPM checks, or keep the ISO for multiple uses), download the ISO and use Rufus to make the bootable USB. Rufus gives extra options and is commonly used for that.

• Media Creation Tool (recommended for most):
  1. On a working PC go to Microsoft’s Download Windows 11 page and click “Create Windows 11 installation media” → Download Now.
  2. Run the tool, choose “USB flash drive,” pick your 8 GB (or larger) USB and let it finish.
• Using the ISO + Rufus:
  1. Download the “Windows 11 Disk Image (ISO) for x64” that you found.
  2. Download and run Rufus. Insert the USB (8 GB minimum; 16 GB recommended).
  3. In Rufus: Device → select USB; Boot selection → SELECT the ISO; Partition scheme → GPT for modern UEFI laptops; click Start and confirm (this will erase the USB).

• Insert the USB, power on and open the Boot Menu (many Lenovos use the Novo button or keys like F12 / Esc / F10 depending on model). Pick the USB (may appear as “UEFI: USB…”). If it doesn’t boot, you can also enable/disable Secure Boot or change boot order in BIOS/UEFI.

• Give the exact Media Creation Tool clicks (with screenshots) or a step‑by‑step Rufus walkthrough.
• Tell you the exact Boot Menu key for your Lenovo model — tell me the model number (e.g., ThinkPad X1 Carbon 8th gen or Lenovo IdeaPad 3 15ITL6).

• Use a USB flash drive (8 GB minimum; 16 GB recommended). Back up any files on the USB — the process will erase it.

1. On a working Windows PC, open Microsoft’s Download Windows 11 page and choose “Create Windows 11 installation media” → Download the Media Creation Tool (MediaCreationToolW11.exe).
2. Insert the USB flash drive into that PC.
3. Run the downloaded Media Creation Tool (right‑click → Run as administrator if needed). Accept the license terms.
4. Choose “Create installation media (USB flash drive, DVD, or ISO file)” and click Next.
5. Choose language/edition (or leave “Use the recommended options for this PC”) and click Next.
6. Select “USB flash drive” and click Next. Choose the correct USB from the list and click Next. The tool will download Windows 11 and create the bootable USB. Wait until it finishes and shows “Your USB flash drive is ready.” Do not remove the USB during the process.

1. Power off the Lenovo laptop. Insert the finished USB.
2. Open the Boot Menu:
   • Many Lenovo models use the Novo button (a small recessed button near the power/side). Press it when the laptop is off to open the Novo Menu → choose Boot Menu.
   • Or press the Boot Menu key while powering on (common keys: F12, F10, Esc or sometimes Enter). If unsure, tell me your exact Lenovo model and I’ll find the right key.
3. In the Boot Menu choose the USB device (it may show as the USB brand or “UEFI: <USB name>”) and press Enter. The Windows installer should start.

• On the installer screen choose “Repair your computer” (bottom-left) → Troubleshoot → Advanced options to get to Startup Repair, System Restore, Command Prompt, or to restore from an image.

• USB not listed in Boot Menu: try a different USB port (use a rear/USB‑A port if available), recreate the media, or try Rufus if Media Creation Tool fails.
• Secure Boot blocks booting: you can temporarily disable Secure Boot in BIOS/UEFI, boot from USB, then re-enable it afterwards.

• Give exact clicks with screenshots for the Media Creation Tool?
• Walk you step‑by‑step while you do it?
• Or give Rufus instructions instead (useful if the Media Creation Tool fails)?

Is this the one to download?

Download Windows 11 Disk Image (ISO) for x64 devices​

Click to expand...

• If you’re not 100% sure of the download source, stop and tell me where you got it. If it’s not from Microsoft, don’t run it.

• Right‑click the file (Downloads → Win11_25H2_EnglishInternational_x64[.iso]) and choose “Scan with Microsoft Defender” (or “Show more options” → “Scan with Microsoft Defender”).
• You can also run a full file hash scan in PowerShell: open PowerShell and run:
  Get-FileHash -Algorithm SHA256 "C:\Users\<yourname>\Downloads\Win11_25H2_EnglishInternational_x64.iso"
  Save that SHA256 value — if you got the file from Microsoft, you can compare it to the official checksum (I can help find the official value if you confirm the download source).

• Right‑click → Properties. If you see an “Unblock” checkbox at the bottom of the General tab, check it and Apply. (This simply removes the “downloaded from the Internet” flag — it won’t bypass Smart App Control entirely.
• If you mount the ISO and run setup.exe, you can right‑click setup.exe → Properties → Digital Signatures and confirm the signer is “Microsoft Windows” (or similar) to be more confident.

• Best: use Microsoft’s official Media Creation Tool or the official download page to make a bootable USB. That method avoids running unknown installers and ensures the media is authentic.
• If you prefer Rufus / balenaEtcher to make the USB, use an ISO you’ve verified by hash/signature and use Rufus’s “Windows To Go / Windows installation” options.

• Open Start → Windows Security → App & browser control → Smart App Control. Turn it Off (choose the temporary option if offered).
• Run the installer / create your USB. Then immediately re‑enable Smart App Control in Windows Security.

• Only disable Smart App Control if you are certain the file is legitimate (official Microsoft download or verified by digital signature/SHA256). Turning SAC off lowers protection.
• Make a backup of important files and, if you’ll change system files, create a System Restore point before proceeding.

• Verify the file name/extension in your Downloads folder (tell me the full filename including .iso)
• Walk you step‑by‑step through scanning, getting the SHA256 hash, and comparing it to Microsoft’s official value
• Walk you through making a bootable USB safely.

• Close any “Open file” or “Run” dialogs. Smart App Control blocks execution to protect you; don’t bypass yet.

• Confirm the exact filename in Downloads: you already have Win11_25H2_EnglishInternational_x64.iso (good).
• Right‑click the ISO → Properties. If you see an “Unblock” checkbox on the General tab, check it and click Apply. This clears the “Mark of the Web” but does not remove Smart App Control’s evaluation.

• Right‑click the ISO → “Scan with Microsoft Defender” (or open Windows Security → Virus & threat protection → Quick scan / Scan options → Custom scan and point it to the ISO).
• If Defender reports clean, we move on. If it flags anything, stop and tell me the exact message.

• Open PowerShell and run (replace path if your Downloads path is different):
  Get-FileHash -Algorithm SHA256 "C:\Users\<yourusername>\Downloads\Win11_25H2_EnglishInternational_x64.iso"
• Copy the SHA256 output and I can help you compare it with Microsoft’s official checksum (or, if you want, I can fetch that official checksum for you). Verifying the hash ensures the ISO wasn’t tampered with during download.

• Mount the ISO: right‑click the ISO → Mount.
• Open the mounted drive, find setup.exe, right‑click it → Properties → Digital Signatures. The signer should be Microsoft (e.g., “Microsoft Windows” / “Microsoft Corporation”). If the signature is valid, that’s another good sign.

• Recommended: use Microsoft’s Media Creation Tool or the official ISO to make a bootable USB. This avoids running downloaded executables on your running system. (Rufus or balenaEtcher also work but are third‑party. If you want I’ll give the exact Media Creation Tool or Rufus steps.

• You can temporarily turn Smart App Control off, run what you need, then re‑enable it. Open Settings → Privacy & security → Windows Security → App & browser control → Smart App Control and switch Off. Note: Microsoft has changed how the SAC toggle behaves in some Insider builds, so the toggle location or availability can vary; if you don’t see that exact option I’ll walk you to the alternate path. Re-enable SAC immediately after. Only do this after you’ve completed the scans & verification above.

• Do not permanently disable Smart App Control or other protections. Only disable briefly for verified, necessary actions.
• If anything looks off (hash mismatch, signature missing/invalid, Defender flags), stop and don’t run the file — I’ll help you re‑download the ISO safely.

• I can walk you through the PowerShell Get-FileHash command and compare the hash to Microsoft’s checksum (I can fetch the official checksum if you want).
• Or I can give step‑by‑step instructions to make a bootable USB with the ISO (Media Creation Tool or Rufus).
• If you prefer to run setup on this machine, tell me and I’ll guide you to temporarily and safely disable Smart App Control, run the installer, then re-enable protection.
