Entrance BIOS (or its modern counterpart UEFI) on Xiaomi devices – a procedure that may be required to configure hardware, change the boot order, update firmware or troubleshoot. Unlike smartphones that use Fastboot or Recovery Mode, on laptops and monoblocks of the brand, entry into low-level settings is carried out through classical methods – using special keys or combinations that depend on the model and version of the firmware.
The main difficulty for users is that Xiaomi does not always adhere to standard solutions: for example, on some models of Mi Notebook or RedmiBook laptops, non-standard keyboard shortcuts can be used, and in new devices with a high-quality keyboard. UEFI Settings input is integrated into the Windows boot menu, and some firmwares also have access to the Windows boot menu. BIOS It is blocked by default, which is designed to protect against inexperienced users, but creates additional obstacles.
In this guide, we will discuss all the current ways to enter the BIOS on Xiaomi devices, including:
- 🔑 Standard keys and their combinations for different models
- 🖥️ Features UEFI and Legacy modes
- ⚙️ Windows Login (for devices with preinstalled OS)
- 🔧 Solving problems if BIOS open-ended
1 What Xiaomi devices have BIOS?
It is important to understand that BIOS (or successor UEFI) It is only present on full-fledged computers of the brand:
- 💻 Mi Notebook Series Laptops (including Mi Notebook Pro, Mi Notebook Air)
- 🖥️ Mi Desktop and Mi All-in-One PC
- 🖼️ Mini-PC Mi Box (not to be confused with the Mi Box) TV-prefix!)
On smartphones, tablets and smart watches Xiaomi BIOS It's not there! It's used instead:
- 📱 Fastboot Mode – for firmware and unlocking the bootloader
- 🔄 Recovery Mode – to reset settings or install updates
- 🛠️ EDL Mode – for deep recovery (only for service centers)
2. Standard keys for entering into BIOS Xiaomi
Most Xiaomi devices use the same keys as other PCs, but there are nuances.

| Mi Notebook Pro (all generations) | F2 or Del | Some versions require Fn + F2 to be retained. |
| Mi Notebook Air (12.5" and 13.3) | F2 | If it doesn’t work, try Esc to call the download menu. |
| RedmiBook 14/16 | F12 (load) → later F2 | The device selection menu is opened first, then BIOS |
| Mi Desktop (monoblocks) | Del | In some versions, it only works with USB-keyboard |
| Mi Box (Mini-PC) | Esc or F7 | You need to connect the keyboard to USB beforehand |
If the standard keys don’t work, try the following options:

3. Entrance BIOS via Windows (for example, UEFI-system)
On modern Xiaomi devices with pre-installed Windows 10/11 and UEFI You can log in to the settings directly from the operating system, and this is more reliable than using keys, because it eliminates the problem of skipping the moment of pressing.
Instructions:

- 🔹 Update Windows to the latest version – on older builds, this item may not be available.
💡
If, after rebooting, the UEFI If you see an empty menu or error, try resetting your settings. BIOS to the factory (the option of Load Default Settings).
4. What to do if BIOS open-ended?
If none of the methods worked, the problem may be related to:
- 🔐 Blocking from the firmware (on some models Xiaomi disabled access to the BIOS for regular users).
- 🖥️ Keyboard malfunction (especially relevant for Bluetooth keyboards – connect wired).
- 🔋 Booting too fast (turn off Fast Boot in Windows settings).
- 🛠️ Hardware failure (for example, chip damage) BIOS).
Decisions:
- Turn off fast booting in Windows: Open the Control Panel → Power. Select Power Button Actions. → Change settings that are not available now. Uncheck the tick from Enable Quick Start.
- Drop it. BIOS through hardware method: Some Xiaomi models (like the Mi Notebook Pro) have a hidden reset button on the bottom panel. To do this: Turn off the laptop and turn off the charger. Turn the device over and find a small hole that says CMOS or RESET. Insert a paper clip into it and hold it for 10-15 seconds.
How to check if Fast Boot is included in the BIOS?

| Parameter | BIOS (Legacy) | UEFI |
|---|---|---|
| Interface. | Text, keyboard control | Graphic, mouse support |
| Loading speed | Slower (checking all equipment) | Faster (parallel initialization) |
| Support for discs | Only MBR (2 TB) | GPT (more than 2 TB, more than 4 sections) |
| Security | Vulnerable to rootkits | Secure Boot Support |
On Xiaomi devices with UEFI Additional features available:
- 🔒 Secure Boot – Protection against unauthorized changes to the bootloader.
- 🖥️ CSM (Compatibility Support Module – Legacy mode emulation for older OSes.
- 🔄 Fast Boot – Accelerated boot (may interfere with the entry of settings).
If your device supports both modes, the settings UEFI You can choose Boot Mode:
