Device: Dell Chromebook 11 3120 (Motherboard “CANDY”)
Processor: Intel Celeron (x86_64)
Internal Storage: 16 GB eMMC
Current firmware: MrChromebox UEFI Full ROM - Version 2026.1 (updated on 14/07/2026 from a previous version 4.20.0 of 15/05/2023)Current firmware: MrChromebox UEFI Full ROM - Version 2026.1 (updated on 14/07/2026 from a previous version 4.20.0 of 15/05/2023)
Main problem:
The Windows installer (tested with Windows 10 22H2, 1809, LTSB 1607, and Windows 11) does not detect the internal eMMC drive. The error message displayed is “Missing media drivers” or no drive appears to select during installation.
Diagnosis performed
1. UEFI Shell: Running the `map` command shows the eMMC appearing as blk0, blk1, and blk2 (block devices), but not as fs0: (mounted file system). This confirms that the firmware detects the hardware but cannot mount it for OS use.
2. Windows Installer CMD: Running `diskpart` and `list disk` shows that the drive does not appear in the list.
3. Ubuntu Live USB: When using an Ubuntu USB drive, the Linux operating system successfully detects the eMMC, confirming that the hardware is not severely damaged.
4. UEFI device path: The displayed path is pciroot(0x0)/pci(0x17x0)/emmc(0x0)/ctrl(0x0), indicating that the eMMC is connected via a PCIe bridge chip.
Please, can someone help me install Windows 10 on the hard drive?
