Chromebox 3 dual boot failure

HELP: Asus Chromebox 3 CN65 flashed Mr. Chromebox firmware and completely removed chromeOS. THEN upgraded storage, ram and wireless. 16gb DDR4 + 2x 500gb SSD’s + WiFi rerouted to back usb port.

  • Everything detected and working properly. Installed windows on one of the SSD’s then went back into the boot menu to install PopOS on my second SSD. Every drive is recognized EXCEPT my PopOS flash drive (created with ventoy). I’ve been recording this whole process in hope to post a video of the results but I am stuck at this stage. Any help is appreciated. Thank you!

Did you use gpt partition, chromeos only accepts gpt? Boot windows, Right-click the PopOS disk and select Properties from the context menu. In the pop-up window, go to the Volumes tab, and then you can see the partition scheme of the disk. if it MBR, reflash with rufus and use the GPT partion. Also, try diffrent drives, sometimes, certain drives don’t get detected. Hope this works :pray:.

ChromeOS was completely wiped from the computer. I used @MrChromebox process to turn it into a normal computer.
