install linux on chromebook without developer mode

To boot your Chromebook anyway, you’ll need to press Ctrl+D when you see this screen. That scary boot message helps keep typical users safe, guiding them through the process of disabling developer mode if they don’t know what’s happening. If they typed in their password, you could capture it and spy on them. For example, you could install a keylogger on a Chromebook using your developer mode access and then pass it along to someone. A Chromebook in developer mode doesn’t have the usual security features. This screen is designed for security purposes. If you ignore this message for long enough, your Chromebook will urgently beep at you to get your attention. The message informs you that your Chromebook’s files can’t be verified - in other words, that the Chromebook is in Developer Mode. You’ll now see a scary-looking message saying “OS verification is OFF” when you boot your Chromebook. Chrome OS normally verifies itself before booting to protect the operating system from being tampered with without your permission. This disables the “operating system verification” feature, so you can modify Chrome OS’s system files and it won’t complain and refuse to boot.

You’ll see a screen saying “To turn OS Verification OFF, press ENTER.” Press Enter to enable developer mode. This prevents less-knowledgable Chromebook users from poking around and enabling it without knowing what they’re doing. This keyboard shortcut isn’t actually listed on the screen anywhere - you have to know it ahead of time. The Recovery screen says “Chrome OS is missing or damaged.” It isn’t, actually - this screen normally just appears when your Chrome OS installation is damaged. For example, on the ASUS Chromebook Flip, it’s not even on the keyboard itself–it’s on the left side of the device. Note that the Power button may be elsewhere on your Chromebook. (The Refresh Key is where the F3 key would be - the fourth key from the left on the top row of the keyboard.) Your Chromebook will immediately reboot into Recovery mode. To do so, press and hold down the Esc and Refresh keys and then tap the Power button. To get started, you’ll need to boot your Chromebook into Recovery Mode.

Recovery Mode is a special boot option where you can also reset your Chromebook to its factory default state. On modern Chromebooks, it’s an option you need to enable in Recovery Mode. On the original Chromebooks, “Developer Mode” was a physical switch you could flip.
