Symptômes

XPS and Precision computers running Ubuntu Linux may fail to boot immediately after replacing the motherboard or restoring the BIOS default settings. This issue may also occur when running a BIOS update from Ubuntu/Canonical resulting in a "No boot device was found" error message.

Cause

The reason for this is that the default BIOS setting for Serial AT Attachment (SATA) operation in these computers is RAID On. As a result, replacement motherboards are set to the BIOS default for SATA operation of RAID On. Updating the BIOS, or re-setting the BIOS to "default" also resets SATA operation to RAID On. This default RAID On setting prevents Ubuntu Linux from detecting the Hard Drive.

Ubuntu Linux systems require the SATA operation to be set to Advance Host Controller Interface (AHCI). Changing this setting back to AHCI enables the computer to boot as normal by correctly detecting the Hard Drive again.

Résolution

If the boot options were deleted, they must be manually re-created with the following steps:
  1. In the BIOS go to System Configuration, SATA operation and enable AHCI. This allows the drive to be seen in Ubuntu and Ubuntu installers.
  2. Go to General, Boot Sequence, and select Add Boot Option.
  3. Under File Name, click the button to the right to bring up the EFI Boot Selection window.
  4. The EFI Boot Selection window is split into two sections, Directories and Files. Under Directories click efi, Ubuntu.
  5. Under Files click shimx64.efi then click Okay, then click Okay again.

  6. Type UBUNTU in the Boot Option Name field:

    SLN309446_en_US__2ubuntu-efi-boot-2-2

  7. Clear all other boot options to ensure that our new boot option is the only one selected.
  8. Click Apply and then Okay to save changes, then click Exit to reboot the computer.
