Let's be real for a second. You probably bought a Chromebook because it was cheap, fast, and the battery lasted forever. But then reality hit. You needed that one specific piece of software—maybe Adobe Creative Cloud, a niche Steam game, or some crusty old .exe file your job requires—and ChromeOS just stared back at you with a blank expression. Now you're wondering about installing Windows 10 on a Chromebook.
It’s possible. It’s also a massive pain in the neck if you don't know what you're getting into.
Most people think you just plug in a USB drive and hit "install." Honestly? If you try that, you'll likely end up with a very expensive paperweight. Chromebooks aren't built like standard PCs. They use a proprietary firmware called Coreboot, which is specifically designed to prevent you from running anything other than Google’s verified software. To get Windows on there, you have to perform what is essentially open-heart surgery on your laptop's software.
The Hardware Reality Check
Before you even touch a screwdriver, you have to check your processor. This is the part where most dreams die. Windows 10 is built for x86 architecture—think Intel and AMD. If your Chromebook is rocking an ARM-based chip (like a MediaTek or a Snapdragon), you can stop right here. It’s not happening. Windows on ARM exists, but the driver support for Chromebook hardware is non-existent.

Even if you have an Intel Celeron or an i5, you've got to worry about the Write Protect (WP) screw. Most older Chromebooks have a physical screw on the motherboard that prevents you from flashing the firmware. You have to take the bottom case off, find that tiny screw, and remove it. Newer models use something called CR50, which requires a special "SuzyQable" or a specific battery-unplugging ritual to disable protection.
It’s finicky. You’ll probably lose a screw in your carpet. You've been warned.
The Coolstar Factor and Driver Hell
If you’re diving into this world, you need to know the name Coolstar. This developer is basically the patron saint of Windows-on-Chromebook projects. Without their custom drivers, even if you successfully install Windows 10, your touchpad won't work. Neither will your speakers. Or your keyboard.
Basically, you'd be staring at a Windows desktop you can't interact with.
Check the Chromebook Windows Compatibility List first. If your specific board name (like "Celes" or "Banjo") says "No Support," believe them. Don't be the person who spends six hours on this just to find out the audio drivers don't exist and you're stuck using Bluetooth headphones forever.
Preparing Your Chromebook for the Flip
First step: Back up everything. Seriously. This process nukes your entire drive. You aren't just "adding" Windows; you are erasing ChromeOS from existence.
- Enable Developer Mode. This isn't the same as the "Developer Channel" in settings. You usually have to hold Esc + Refresh and tap the Power button. It’ll give you a scary screen saying "ChromeOS is missing or damaged." It’s lying. Press Ctrl+D.
- Flash the UEFI Firmware. This is the big one. You’ll use a script created by MrChromebox. You open the ChromeOS terminal (Ctrl+Alt+T), type
shell, and then paste the command from MrChromebox.tech. - Select "Full ROM Firmware." If this option is greyed out, your Write Protect is still on. Go back and check that screw or battery connection.
Once the firmware is flashed, your Chromebook is no longer a Chromebook. It’s a "Chromebox" running a standard UEFI BIOS, just like a Dell or an HP.
Creating the Windows Media
You need a 16GB or larger USB drive. Don't use a cheap, generic one you found in a drawer; Windows installation is sensitive to read/write errors. Use the official Windows 10 Media Creation Tool on a different PC to make a bootable installer.
Because Chromebooks often have tiny eMMC drives (32GB or 64GB), Windows 10 is going to feel cramped. I’d suggest using a "Tiny10" ISO or a debloated version of Windows if you're comfortable with that, but for a standard experience, just be prepared to have almost no space left for files.
The Actual Installation Process
Plug the USB into your Chromebook and turn it on. Since you flashed the MrChromebox firmware, you’ll see a rabbit logo or a custom boot screen. Mash the Esc key to enter the boot menu and select your USB drive.
The Windows installer will look familiar. However, your touchpad won't work yet. You’ll need a USB mouse plugged in to click through the menus.
When you get to the "Where do you want to install Windows?" screen, delete every single partition you see. There will be about 20 of them (Google loves partitions). Keep deleting until you have one big block of "Unallocated Space." Click next.
Solving the Driver Puzzle
Once you hit the desktop, it’s going to feel like a victory. It’s not. Not yet.
Your screen might be at a weird resolution, and the keyboard will be dead. You need to run the Coolstar bridge drivers and the specific chipset drivers for your Intel or AMD processor. This is where you'll find out if your hardware is actually compatible.
- Keyboard: Most Chromebook keys map differently. You'll need a remapper script to make the "Search" key act like the Windows key.
- Audio: This is the most common failure point. Many Chromebooks use I2S audio, which Windows hates. You might see a "No Audio Output Device Installed" error that never goes away.
- Touchscreen: If you have a flip-style Chromebook, the rotation sensor often fails in Windows. It’s annoying.
Is It Actually Worth It?
Honestly? Usually no.

Unless you have a high-end Chromebook like a Pixelbook or a top-tier Acer Spin with an i5 or i7, Windows 10 will run like molasses. The 4GB of RAM found in most budget Chromebooks is barely enough to keep Windows 10 alive, let alone run Chrome (the irony) or Word.
Performance is often sluggish. You’ll miss the 8-second boot times of ChromeOS. You’ll definitely miss the battery life, which usually drops by about 30-40% once Windows starts hogging resources.
However, if you have an old Chromebook that’s reached its "End of Life" (AUE) and stopped getting Google updates, this is a great way to recycle the hardware. An unsupported Chromebook is a security risk; a Chromebook running Windows 10 is a functional, if slightly slow, laptop.
Actionable Next Steps
If you're still determined to do this, here is your checklist to avoid a bricked device:
- Find your Board Name: Go to
chrome://systemand look for "hardware_class." Search that name on the MrChromebox and Coolstar sites before you buy a single USB drive. - Get a USB Mouse: You cannot finish the Windows setup without one. The touchpad will not work during installation.
- Disable Write Protect: Physically open the device or use the SuzyQable method. There is no software bypass for this on most models.
- Download Drivers Early: Put your Windows drivers on a second USB drive before you start. You won't have Wi-Fi on the Chromebook immediately after installing Windows, so you won't be able to download them then.
- Keep a Recovery Drive: Always have a ChromeOS Recovery USB handy. If you hate Windows, you can usually flash the "stock" firmware back and return to ChromeOS—but only if you backed up your original BIOS during the MrChromebox script execution.
Installing Windows on a Chromebook is a rite of passage for hardware nerds. It's a fun weekend project, but it’s rarely a "daily driver" solution for someone who just wants their computer to work. Be patient, expect things to break, and keep your screwdriver handy.
