XPS Notebooks: Ruling out a change to the BIOS default settings has caused a No POST / No Boot / HDD or SDD not detected issue



The following article deals with changes to the default BIOS (Basic Input Output Setup) setting can cause an XPS notebook to fail to POST, Detect the drive or Boot to the operating system.

  1. Introduction
  2. No POST / No Boot / Drive Not Found Symptoms
  3. XPS Notebook Factory Settings Reference Matrix
  4. Steps to resolve changes to the default settings causing a Drive not found or No POST / No Boot issue

1. Introduction

The aim of this article is to provide a guide that outlines the default BIOS settings for XPS notebooks. This is to aid with the troubleshooting of No Boot / No Post issues on XPS platforms. In some circumstances it has been noted that it is making changes to these settings which can cause No Boot / No Post issues. The guide also provides one method of assisting HDD/ SSD no detected issues.

If no BIOS changes were made prior to the issue occurring, then you would be best going to the article linked at the bottom of section 4 instead.

4. Steps to resolve changes to the default settings causing a Drive not found or No POST / No Boot issue

Note: It is important to note that using the BIOS factory reset option WILL NOT revert all settings back to defaults. Follow the steps in the section below to ensure that ALL settings are returned to factory default. If you can't enter the BIOS then your issue isn't covered by this article. Please check the link at the bottom of this article for further help.

The matrix in the section above contains the default factory settings in relation to the hard drive / SSD. These settings should be verified and checked as a first step in troubleshooting No BOOT / No POST issues, where the notebooks default settings have been changed just before the issue started to occur.

  1. Check the current operating system on the PC is supported on your model by referring to the Dell support website to see if that operating system is supported.

    1. Go to the support site and enter your Service Tag or Express Service Tag

    2. Click on the Drivers and Downloads drawer

    3. Click on the Change OS button to see the operating systems supported on your PC

  2. Enter the systems BIOS by rapidly tapping on the F2 key during the systems start-up and reset the BIOS settings to factory defaults by pressing the Alt + F keys or alternatively by clicking on the Restore Settings button.

  3. After resetting the BIOS settings to factory defaults, check that all of the individual Boot settings are correct by referring to the matrix table.

If you are still experiencing No POST or No Boot issues after this or are unable to enter the BIOS, then please check out the following link for further troubleshooting steps to identify your issue:

If you don't install the IRST driver onto the Operating System (OS) DVD or USB key before they attempt the install (windows, not Ubuntu), they may encounter "HDD/SSD not detected" symptoms.

Troubleshooting:

  1. Was a recent operating system install attempted?

    1. If it was, did you install the IRST driver on the OS DVD or USB key, prior to the installation attempt?

    2. If not, download the F6 iRST driver from the Dell support site onto a USB key and then retry the OS install on your own system again.

If you are still experiencing HDD not detected issues after this, then Please check out the following link for further troubleshooting steps to identify your issue:
