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

In many cases 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.

7. Rest 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 top right corner of the screen.
  3. Depending on the BIOS, you may need 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.

8. 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, etc.).
  • Digital Cameras and Video Recorders.
  • USB storage devices.
  • CDs or DVDs from all optical drives.

The only devices 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.
