System Details
- Device: YAHIKO (HP Chromebook, Intel N100)
- OS: ChromeOS
- Firmware Type: Stock firmware (no RW_LEGACY / no UEFI)
- Firmware Version: Not installed (script cannot run)
- Internal storage type: eMMC
Summary of the Issue
I am trying to install Windows on my Chromebook using MrChromebox firmware tools, but I am completely blocked.
-
Ctrl + L shows “Alternate bootloaders are disabled”
-
USB boot shows “No valid image detected”
-
Running the firmware utility script fails with:
“The ‘no new privileges’ flag is set, which prevents sudo from running as root”
Because of this, I cannot install RW_LEGACY or UEFI firmware, so I cannot boot Windows.
Steps to Reproduce
-
Enabled Developer Mode
-
Opened crosh (Ctrl + Alt + T)
-
Typed shell
-
Tried to run: cd; curl -LO https://mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh
-
Got error: sudo: The “no new privileges” flag is set
-
Pressed Ctrl + L “Alternate bootloaders are disabled”
-
Tried booting USB “No valid image detected”
Expected Behavior
I want to install Windows, so I expected:
firmware script to run
RW_LEGACY or UEFI to install
Ctrl + L or USB boot to work,
but I’m unsure if there is any way to do this without opening the device. If hardware write-protect removal is required, I’m not confident what exactly I should be looking for inside (battery disconnect, write-protect screw, etc.), so any guidance would be appreciated.
