Hi, I have an HP chromebox g3 with the 32 gb emmc storage. I have bought an adapter that connects to the m2 wifi port and allows to use an nvme m2 ssd drive. It shows up as a external drive in chrome os (non developer mode).

I have switched to developer mode to see if I can make the ssd drive the primary drive to install chrome os. How would I go about doing this? I can't find any information anywhere.

I done some research: /usr/sbin/chromeos-install /dev/nvme0n1

That is how my drive shows up in fdisk. I'm having an issue one where:

umount://run/chromeos-config/v1: no mount point specified


What am I missing or doing wrong? Not even sure if this is possible at all. Thanks for any good replies.

I did some testing and I believe I found the answer.

Steps: Switch to developer mode.

Run this script: https://mrchromebox.tech/#fwscript

Either use RW_Legacy or Full Rom

Either use a linux live usb of your choice or windows installer to delete partitions in the emmc storage (all of them) and setup the nvme ssd drive with a new partition table, I did this with windows 11 installer.

Exit the installer or linux live usb without installing an os.

Go back to secure mode of Chrome OS (unless you want to stay in developer mode of chrome os) and that reinstalls chrome os and when you get to chrome os and check files, you should see that it is using the nvme ssd drive as the main drive!

The emmc is detected as external drive. I updated to the beta channel to see if anything would  change with the disks but it stayed the same, and the best part is that chrome os is in secure mode! I will try to post a screenshot.
