Hey CloudReady Users,

After releasing v68.4 Monday, we’ve noticed an issue where a handful of Dell models cannot find the OS after updating (“No Bootable Device” error). This only occurs if they are installed in UEFI mode. For the past 24 hours, we have had updates suspended to prevent anyone from experiencing these issues while we work on a fix and test it.

Here’s a rundown of what’s going on:

Which devices are affected by this bug:

  • Affected models: Dell Latitude laptops that end in “20” or “30”, and Dell Optiplex desktops that end in “90”. E.g. Dell Latitude E5420, Dell Optiplex 390.

  • Why this happens: As part of the existing UEFI install process, these devices may have required manual entry of the boot file path in their BIOS. The v68.4 update resizes the EFI partition and renders that path invalid.

What to do if you've been affected by this issue:

  • BIOS settings adjustments can resolve this issue in all known cases

    • Reset to default: Usually, resetting the device to defaults works (make sure Secure boot is disabled after the reset)

    • Re-enter boot path: If a reset to defaults does not help, you can manually re-enter the boot file path. Visit our supported models list and click through to the detailed notes on your model for detailed steps.

  • Contact us: Contact us at support if you have issues, questions, or experience something different than what’s described here.

How we are addressing this bug:

  • The fix: We are currently testing a fix now. We will deploy this fix as soon as we can.

    • This fix will prevent the issue for devices being updated going forward. If your device has already experienced this issue, you will have to adjust BIOS settings as outlined above.

  • Minimizing the risk: We will be adding code to manage EFI entries when recreating the EFI partition upon upgrade for affected devices only.

Updates have been resumed to v66 on the Stable Channel:

  • We have resumed updates to the previous stable release, v66 for customers who are on older versions. We will announce again once a patch for v68.4 is released.

  • If you’re in a hurry to get v68.4, you can subscribe to the Beta or Dev Channels. Make sure you don’t move affected models (see above). If you’re unsure which models might be affected, please contact us.

Now that we have a working fix, we should have a patch ready for you in the coming days and will resume updates to v.68.4. While most devices are and will be unaffected, feel free to reach out to us with questions or concerns.

If you’ve been affected by the bug or the delay of updates, we apologize for the inconvenience.

Stay tuned for further updates.
