How to Transform Dell Chromebook 3120 to Windows 10

Описание: Transforming a Dell Chromebook 3120 to run Windows 10 is a multi-step process that involves replacing the Chromebook's firmware with a custom UEFI BIOS. This is necessary because Chromebooks are typically designed only to boot the ChromeOS operating system.

Here are the general steps based on community tutorials:

1. Hardware Preparation (Disable Write Protection)
The Chromebook's firmware is write-protected to prevent unauthorized changes. You must disable this protection first.

Disassemble: Power off the Chromebook, unplug it, and open the back cover.

Locate the Write Protect Screw: Find and remove the hardware write protection screw. This is often marked on the motherboard or indicated in specific online guides for the Dell 3120 model.

2. Firmware Modification (Install UEFI BIOS)
You need to switch the device from its restrictive ChromeOS firmware to a custom, full UEFI BIOS (like the ones provided by the MrChromebox firmware project).

Enter Developer Mode: Turn on the Chromebook while holding Esc + Refresh, then press Ctrl + D to enter Developer Mode.

Access the Shell: Once ChromeOS boots, press Ctrl + Alt + T to open the Crosh terminal, then type shell and hit Enter.

Run the Firmware Utility: Download and run the firmware flashing script. This script will replace the locked-down BIOS with one that can boot standard operating systems.

3. Windows Installation
After successfully flashing the UEFI firmware, you can proceed with a standard Windows installation.

Create Bootable Media: On another computer, create a bootable USB drive with the Windows 10 installer using a tool like the Media Creation Tool or Rufus.

Boot to UEFI: Plug the Windows USB drive into the Chromebook. When you power it on, press the appropriate key (usually Esc or F2) to bring up the boot menu.

Install Windows: Select the USB drive to boot from, and follow the standard Windows 10 installation prompts. You will likely need to format the internal drive before installation.

⚠️ Important Considerations:

Drivers: The biggest challenge is often finding all the necessary drivers (especially for Wi-Fi, touchpad, and sound) to work correctly under Windows, as Dell did not officially release Windows drivers for this specific Chromebook model.

Performance: The Dell Chromebook 3120 has limited internal storage and low-power hardware (often a Celeron processor and 2GB/4GB of RAM), so Windows 10 performance will be slow. Many users opt for lighter versions like Windows 10 Tiny or similar lightweight distributions.

Warning: This process voids the manufacturer's warranty and carries a risk of bricking (making unusable) your device if done incorrectly. It is best suited for experienced users.
