Fast Boot is a feature in BIOS that can help to reduce the time it takes to boot your computer. If Fast Boot is enabled:

  • Boot from Network, Optical, and Removable Devices are all disabled.
  • Video and USB devices (keyboard, mouse, drives) will not be available until after the operating system loads.

To enable Fast Boot:

  1. During boot, enter the BIOS setup by pressing F2.
  2. Go to the Boot>Boot Configuration menu.
  3. Enable the Fast Boot setting.
  4. Press F10 to save and exit.
 
Caution
When Fast Boot is enabled, the following problems can occur:

You cannot access BIOS Setup during boot with the F2 key.
You cannot boot to an optical drive or USB drive to install an operating system.
You cannot boot to a network.


Fast boot recovery
The BIOS can see that a previous boot was unsuccessful. When the computer is booted, if the previous boot failed during POST, Fast Boot is disabled and the following message displays: The previous boot attempt failed. Would you like to restore Fast Boot on the next boot? (Y/N).

If the boot fails after POST, no message displays, and Fast Boot is still active.

Disabling Fast Boot from the power button menu
The power button can be used to recover if you encounter Fast Boot problems. The power button menu is accessible via the following sequence:

  1. Make sure the system is off, and not in Hibernate or Sleep mode.
  2. Press the power button and hold it down for three seconds, then release it before the 4-second shutdown override. The power button menu displays.
  3. Press F3 to disable Fast Boot.
