If you have an older Chromebook and can’t use Chrome extensions like **Chromebook Recovery Utility** to create a bootable USB (for example, to install **MrChromebox**), you can use **Crosh** instead, as long as you have access to shell (such as in Developer Mode).

**Steps**
Press **Ctrl + Alt + T** to open Crosh.
2. Type:

shell

Plug in your USB drive.
Find your USB device:

lsblk

Write the ISO to the USB drive:

sudo dd if=/path/to/your.iso of=/dev/sdX bs=4M status=progress oflag=sync

Replace **/dev/sdX** with your USB device (for example, **/dev/sdb**).

**Important:** Do **not** use a partition such as **/dev/sdb1**. Use the entire device (/dev/sdb), as this command will erase everything on the USB drive.
I hope this helps! If you have any questions, problems, or suggestions, feel free to leave a comment.

Hi I am using an old t430s with chromeosflex. No issues so far. I got a message saying there are two firmware updates available (KEK CA 2023 and UEFI 2023). Both fail when I click install.

Any idea why? I thought there were no firmware updates for the t430s from Lenovo available.

Hola...

Tengo muchos meses batallando con una Lenovo Ideapad Slim 1 la cual logre instalar Chrome OS Flex pero quiero volver a Windows y esta no me deja entrar en la Bios...

Entro al menu de selección con el botón NOVO pero al seleccionar BIOS SETTING esta solo se reinicia y carga el sistema de Chrome

A través del contenedor Crostini previamente activado. pasos:

1 - Instala Flatpak siguiendo las indicaciones

2 - Instala Aurynk

3 - Habilitar opciones de desarrollador:

Ve a Ajustes → Acerca del teléfono

Pulsa el número de compilación 7 veces

Las opciones de desarrollador aparecerán en Configuración.

Habilitar la depuración inalámbrica: (para Android 11+)

Ve a Ajustes → Opciones de desarrollador

Activar la depuración inalámbrica

4 - Inicia Aurynk desde el menú de aplicaciones.

Haz clic en "Agregar dispositivo" (el botón +).

En tu dispositivo Android:

Pulsa "Emparejar dispositivo con código QR" en Depuración inalámbrica.

Escanee el código QR que se muestra en Aurynk.

Teóricamente puedes hacerlo a través de cable USB pero a mi no me a funcionado.

Si en preferencias de Mirroring aumentas el btirate a 16 obtendrás una muy buena calidad de imagen y con un lag imperceptible. En mi caso probado con el juego Eve Echoes.

Hay un bug con la opción de compartir audio, si la activáis no os funciona el mirroring, hasta que lo corrijan desactivar esa opción.

I have on a few older intel models and everything seems to work just fine. I’ve been thinking about refurbishing older PCs and laptops that M$ Windows doesn’t support and instead of putting Linux on it, just Flex OS as a safe simple web machine. If it works on more older hardware than DDR3 I may have found some ways to recycle a bunch of my E-waste into something useable.

Anyone who has got all the hardware working in ChromeOS on a Macbook 12 Retina 2017?

Using latest version of chrome on Windows 11 , Lenovo Thinkbook 16 (16GB Ram ) . I use chrome for reading research papers. GPU reaches 95% when chrome freezes. I am not a techy guy so idk much. Tried latest and older version of chrome too but no significant improvement.

Has anyone got any information on it's functionality on the laptop go 1? I heard about the sleep and battery detection issues, just wondering if anything has changed since then.

Any help would be appreciated! I'm currently running heavily debloated windows 11 Pro, but I want less idle usage and the material aestheticm

After downloading from Chromebook Recovery Utility, I transferred the USB in my laptop, and tried to boot it from the file (bootx64.efi). It opens up GNU GRUB version 2.12, and there's these options:

local image A

local image B

verified image A

verified image B

Alternate USB Boot

After trying all the options, all of them shows the same black screen result. Tried to Escape + Refresh + Power multiple times, but nothing works.

It would be nice if someone could help me on this🙏

I have an old Dell with AMD A6 7310

So running into issues with some video formats showing black screen.

H.265 doesn't work, just black screen.

Subtitles don't work and can't be managed.

Any way to get a better video player?

I've heard about VLC, but my system says no linux support.

I had an older chromebook and eventually had support for vlc.

Is google holding features back for flex?

deje chrome os flex con todo y la verdad esta muy bueno pero solo necesito que el audio funcione sin tener que usar audifonos blutu o audifonos usb c pero el rendimiento bueno y mi bateria al jugar y ver videos dura algo mas alguien tiene una solucion (tengo que usar el canal beta para que mi tarjeta wifi de mi laptop sea funcional aunque no se porque, porque antes no tenia ese problema creo que era como en chrome os flex 147 o 146 cuando si funcionaba sin tener que hacer eso) ayuda

why my post was blocked? I finally installed Flex on an external drive connected to my laptop (Lenovo ThinkBook 15 ITL Gen 2) via a USB-SATA adapter (my laptop doesn't have built-in SATA ports). It’s the full installation, not the Live version. I really like the design—I set it up for slow window minimize/maximize animations. Can you suggest any other cool design tweaks? I’m planning to install OpenVPN and Horizon by Omni.

Hello, all! So, I need a Recovery Image for OSFlex in the preferably canary or stable channel but if anyone manages to find a Dev channel or beta channel too, that would be alright. As long as it's not the enterprise one! So, I'm looking for Reven v103. I tried out the normal ChromeOS Flex installer via the image AND via the Cb Recovery utility (which barely ever works)... and when I get to boot, the ChromeOS Flex splash appears and my guess is, the GPU Hangs while loading bc the ChromeVox spoken feedback message will play as well as the startup chime. So I need a certain recovery image that still supports Intel Graphics HD 4000. THANK YOU ALL!

I have a really old laptop from the 2009/2010

ASUS X52F

I have windows installed on it but it's extremely slow because it can't handle windows anymore.

I am trying to install the Chrome Os Flex on it. I used the recovery utility tool from Chrome and installed it on a USB drive. Now im trying to boot it, but it just doesn't go through.

I can see the drive in the Boot Page. I also have UEFI Boot option enabled.

When i click on save and the windows attempt to restart, a cursor shows up on the top-left corner of the screen and it doesn't do anything.

Anyone had an issue like this before?

is this normal for chromeosflex to take this much storage!

Folks, my aging HP Envy 15t k100 laptop from a previous life is running absolutely stunning on KUbuntu 26.04

But is there any advantage I can gain by installing ChromeOSFlex over Kubuntu?

My primary usage of this device currently is for applying for jobs on LinkedIn, so some light editing documents (resume). I also do some very light programming in antigravity (it has new 16GB ram DDR3) ram. But that's it. I don't watch videos or listen to music since the laptop is very old.

I maybe getting a new laptop but I want to maybe turn this into something useful when I do my programming on another laptop. So is there any advantage I can get using chromeos over the Kubuntu that it currently has?

Anyone ever tried ChromeOS Flex on a uncertified device? I have a Lenovo Yoga 510 and I want to try ChromeOS Flex on it. Does it have touch drivers, and is it stable?

I’ve fully installed ChromeOS Flex on my mid-2011 MacBook Air. it’s the only operating system on my laptop, however, it won’t boot anymore. it keeps playing the apple boot sound repeatedly and I can’t get it to move past that. I’ve tried reset SMC, NVRam/PRam many times but nothing has worked. ive also tried to boot into recovery mode, which solved the problem before, but that is not working anymore. what can I do?

After a system update yesterday all my streaming websites stopped working.

Got drm errors.

Changed hardware acceleration in flags

Allowed restricted content.

Still won't stream from desktop websites.

Using a HP Elitedesk 800 g2 sff

It's on the Flex certified list.

Any suggestions?
