Lenovo Flex 5 Chromebook - Can't See Internal Drive

I have entered developer mode, disabled write protect, and flashed with MrChromebox UEFI firmware. But now when I boot to a Linux USB, it can’t see the internal drive (I think NVME drive?).

When I get to the page to partition your drive, the only drive that shows up is the USB I am running the installer from.

I also tried using the terminal from linux mint to find the drive but wasn’t able to see any nvme drives or any other drives besides the usb one.

Any idea how to make the internal drive show up?

Thanks

Some more information - I was unable to see the drive in both a Debian 12 (Bookworm) install, and LinuxMint. I also wasn’t able to see the drive from the UEFI shell, although I’m not 100% sure I have the right commands.

I am going to try Pop!_OS next.

The model is TAEKO‑XLTF.

I’m seeing some other posts about Taeko ones having this issue, but with no resolution

In Pop, I get to this exact screen and no drive shows up:

It seems like this is a weird chromebook model. On the lid it says Chromebook Plus. It’s Lenovo. The sticker on the back says IP Flex 5 Chrome. In the recovery screen it said TAEKO-XLTF.

unfortunately TAEKO is probably not going to get fixed until I can get my hands on one

I think I could help with that. I’ll send you a connect on LinkedIn.

aside from firmware, I have some unlikely suggestion:

  • The drive is knocked loose somehow so could be re-seated
  • Drive may have failed in some way but this would require the drive to be transferred to a test rig if that doesn’t cause any problems…

it’s a hardware/firmware issue. TAEKO uses a PCIe to eMMC bridge chip, which requires some special handling (ie, drivers) which it does not have in edk2 currently

beyond my realm sir… :sweat_smile:
