Great choice! A clean install is the best way to get a super-fast system free from bloatware. The process might look a bit intimidating, but don't worry—with this guide, we'll walk through it step-by-step, complete with screenshots for every part.\n\n## #1 Key Preparation (Don't Skip!)\n\nBefore we begin, let's get everything ready. This is the most important part to ensure a smooth process.\n\n<Callout variant=\"danger\" title=\"Critical Warning! Back Up Your Data\">\nThis is the most crucial step. A clean install will **delete everything** on your primary drive (usually Drive C:). Please, please back up all your documents, photos, and important files to an external hard drive or cloud service before you start.\n</Callout>\n\n1. **Prepare a Windows 11 Bootable USB:** This will be our installation tool. If you haven't made one yet, follow our simple guide here.\n   - **Read more:** [Complete Guide: How to Create Windows 11 Bootable USB with Rufus](/blog/how-to-create-windows-11-bootable-usb-rufus)\n2. **Internet Connection (Recommended):** It's best to have an internet connection ready. This helps Windows grab important updates and drivers automatically during setup.\n3. **Note Down Your Product Key (To Be Safe):** If your previous Windows was genuine and linked to a Microsoft account, your key is likely digital and will activate automatically. However, if you have a separate retail key, it's good to write it down.\n\n## #2 Installation Process, Step by Step\n\nEverything ready? Let's start the installation.\n\n### 1. Booting from the USB Drive\n\n- Plug your bootable USB into your laptop or PC.\n- Restart your computer and get ready to enter the BIOS/UEFI menu. The key to press varies, but it's usually one of these: <kbd>F2</kbd>, <kbd>DEL</kbd>, <kbd>F10</kbd>, or <kbd>F12</kbd>. Press it repeatedly as soon as your computer starts up.\n- **Example on My MSI Laptop:** I press the <kbd>DEL</kbd> key right when the MSI logo appears.\n\n![MSI Laptop BIOS Screen](/images/_posts/windows11/install-windows-11/virtualbox/MSI_bios.webp \"BIOS looks might vary, but the goal is the same: find the Boot menu.\")\n*BIOS screens can vary, but the principle is the same: find the Boot menu.*\n\n- Once in BIOS, look for the **\"Boot\"** or **\"Boot Priority\"** menu. Set your USB Flash Drive as the number one boot option (`Boot Option #1`).\n- Save your changes and exit (usually by pressing <kbd>F10</kbd>). Your computer will restart and boot from the USB.\n\n### 2. Starting Windows Setup\n\n<Steps>\n<Step>\n**Select \"Previous Version of Setup\"**\nThe Windows setup screen will appear. Don't click 'Next' yet. Instead, look for the link at the bottom left that says **\"Previous Version of Setup\"** and click it. This is a small trick to start the standard, more familiar installation flow.\n\n![Select Previous Version of Setup](/images/_posts/windows11/install-windows-11/virtualbox/1.webp \"Initial Windows 11 setup screen, select 'Previous Version of Setup'.\")\n</Step>\n\n<Step>\n**Configure Language and Regional Settings**\nThe next screen will ask for your language, time format, and keyboard. Click **Next**.\n\n![Language and Regional Settings](/images/_posts/windows11/install-windows-11/virtualbox/2.webp \"Windows 11 setup screen for language and region selection.\")\n</Step>\n\n<Step>\n**Start Installation**\nClick the large **\"Install now\"** button to begin the process.\n\n![Click Install Now](/images/_posts/windows11/install-windows-11/virtualbox/3.webp \"The 'Install now' button to start the installation process.\")\n</Step>\n\n<Step>\n**Activate Windows**\nSetup will ask for a product key. If your license is linked to your Microsoft account, just click **\"I don't have a product key\"**.\n\n![Windows Activation Options](/images/_posts/windows11/install-windows-11/virtualbox/4.1.webp \"Option to enter a product key or skip it.\")\n</Step>\n\n<Step>\n**Choose Windows 11 Edition**\nSelect the edition that matches your license (e.g., Windows 11 Pro). Click **Next**.\n\n![Choose Windows 11 Edition](/images/_posts/windows11/install-windows-11/virtualbox/4.2.webp \"List of available Windows 11 editions.\")\n</Step>\n\n<Step>\n**Choose Installation Type**\nAlways select **\"Custom: Install Windows only (advanced)\"** for a truly clean installation.\n\n![Choose Custom Installation](/images/_posts/windows11/install-windows-11/virtualbox/5.1.webp \"Selecting 'Custom' option for full installation control.\")\n</Step>\n\n<Step>\n**Managing Partitions (Critical!)**\nFind the partition where your old Windows is located. Select each related partition (System, MSR, Recovery, Primary) **one by one**, then click **Delete**.\n\n<Callout variant=\"warning\" title=\"Warning!\">\nThis step will delete all data on the selected partitions. Make sure you have backed up your important files.\n</Callout>\n\n![Daftar Partisi Awal](/images/_posts/windows11/install-windows-11/virtualbox/6.1.webp \"Daftar semua partisi yang ada sebelum dihapus.\")\n![Unallocated Space](/images/_posts/windows11/install-windows-11/virtualbox/6.2.webp \"Tampilan setelah partisi dihapus, menyisakan Unallocated Space.\")\n![Proses Hapus Partisi](/images/_posts/windows11/install-windows-11/virtualbox/6.3%20Tambahan.webp \"Menghapus partisi sistem satu per satu.\")\n\nOnce you have only one block of **\"Unallocated Space\"**, select it and click **Next**.\n\n</Step>\n\n<Step>\n**Installation Progress**\nWindows will start copying files. The computer will restart several times. Just let it do its thing.\n\n![Installation Status](/images/_posts/windows11/install-windows-11/virtualbox/7.1.webp \"Layar 'Installing Windows' with progress bar.\")\n</Step>\n</Steps>\n\n## #3 First-Time Setup (OOBE)\n\nAfter the core installation is complete, you'll go through a series of setup screens called OOBE (Out of Box Experience).\n\n<Steps>\n<Step>\n**Region and Keyboard**\nFollow the prompts to select your country, keyboard layout, and connect to Wi-Fi.\n\n![Select Region](/images/_posts/windows11/install-windows-11/virtualbox/8.1.webp \"OOBE screen to select country or region.\")\n</Step>\n\n<Step>\n**Sign in with Microsoft Account**\nI highly recommend signing in with your Microsoft account. It syncs your settings and automatically activates your Windows digital license.\n\n![Microsoft Account Sign In](/images/_posts/windows11/install-windows-11/virtualbox/8.2.webp \"Screen to sign in with a Microsoft account.\")\n</Step>\n\n<Step>\n**Final Personalization**\nYou'll be asked to create a PIN, set privacy settings, and choose your interests for customization.\n</Step>\n</Steps>\n\nOnce you're through all that, you'll finally land on your clean, fresh Windows 11 desktop!\n"}
