3. Verify the Computer Finishes Initial Power-Up (POST)

 

Often a computer will not attempt to hand off control to the operating system. If you power the computer on and you see a Dell logo screen with a bar at the bottom, and that bar fills up completely and disappears, then your computer has successfully completed POST.

4. Unplug All External Devices

 

A piece of hardware may be interfering with the normal boot process of Windows. Try unplugging all devices from your computer, including:

  • Printers
  • Scanners
  • Media Card Readers
  • Small Media cradles (iPod, PDA, MP3 player, so forth)
  • Digital Cameras and Video Recorders
  • USB storage devices
  • CDs or DVDs from all optical drives

The only devices that you should leave attached to your computer are your monitor, mouse, and keyboard, if the computer is a desktop.

If an external device is preventing the system from booting, then boot to the system BIOS (F2 at boot for Dell systems) then edit to boot sequence to ensure that the device in question is listed after the system boot drive in the boot sequence. Save the changes in the BIOS then test to see if the device still prevents the system from booting.

If the device still prevents a boot, then leave the device disconnected during the boot process and reconnect once the system is in Windows.

6. Reset the BIOS to Default Values

 

If your computer is set to first attempt to boot to another device, this may cause issues with successfully booting to Windows. To reset your computer's BIOS to factory defaults, perform the following steps:

  1. Restart the computer.
  2. At the Dell logo during restart, tap the <F2> key repeatedly until you see Entering Setup in the upper right corner of the screen.
  3. Depending on the BIOS, you may have to press a key listed at the bottom of the screen to load default settings. For example, <F9> on the Inspiron N5110.
  4. Press ESC to exit the BIOS, and be sure to select Save and Exit to save your changes.
NOTE: If resetting the BIOS to factory defaults does not resolve the issue, you may also try to update the BIOS to the latest version to resolve issues related to the BIOS of your personal computer or tablet. See Dell Knowledge Base article What is BIOS and How to Download and Install the latest BIOS? for more information about BIOS update or downgrade procedure.
 
NOTE: System BIOS may get corrupted if the BIOS upgrade or downgrade procedure is not completed successfully or interrupted.
A corrupt BIOS is one of the possible causes of your personal computer unable to complete POST or some times even boot into the operating system.
If your Dell personal computer or tablet supports BIOS recovery, you can recover the corrupt BIOS by using the BIOS recovery method applicable for your Dell personal computer or tablet. See Dell Knowledge Base article BIOS Recovery options on a Dell PC or Tablet for more information.

7. Run a Computer Diagnostic

 

To determine if your computer is experiencing a hardware problem, run the Dell Online Diagnostics.

If you are unable to boot the system to access the Dell Online Diagnostics, use the Dell Pre-boot System Diagnostics.

NOTE: For Dell Latitude laptop PCs, you may try to recover the personal computer using the forced ePSA method. For more information, see Dell Knowledge Base article How to Use Forced ePSA to Recover from POST or Boot Failure.
