General Information and FAQs

What is BIOS Setup?

The Basic Input Output System, or BIOS, is a very small piece of code contained on a chip on your system board. When you start your computer, BIOS is the first software that runs. It identifies your computer’s hardware, configures it, tests it, and connects it to the operating system for further instruction. This is called the boot process.

Entering the BIOS setup utility allows you to change the boot process order as well as a wide variety of hardware settings. It is not recommended for an inexperienced user to change settings in the BIOS unless they are being instructed to do so by a trusted source.

Over time, limitations in BIOS led to the creation of a new firmware interface called Unified Extensible Firmware Interface, or UEFI. UEFI is very similar to BIOS, but has some advantages. It can boot from disks over 2-TB in size, has a graphical user interface with network capability, and is backward and forward compatible. UEFI is expected to eventually replace BIOS.

BIOS and UEFI

BIOS and UEFI (Unified Extensible Firmware Interface) are two firmware interfaces for computers which work as an interpreter between the operating system and the computer firmware. Both of these interfaces are used at the startup of the computer to initialize the hardware components and start the operating system which is stored on the hard drive.

UEFI was introduced in Windows 8 to replace BIOS. UEFI firmware provides technical advantages over a BIOS system.

General solution to enter BIOS Setup

2. Immediately press the BIOS key 5-10 times after the power on button is pressed or restart the system and press the BIOS key when the Lenovo logo is displayed. The BIOS key varies based on your product series.

Note: You may get more detailed information if you select what series your computer belongs to at the top.

Once the Boot menu has been found, search for the Boot Order to be changed. At times, the boot option shown in the following figure may be hidden in other tabs. Scroll around and try to locate this option.

Note: The steps listed below are for the example BIOS only; your computer's BIOS may be slightly different.
To change which device to boot from first, follow the directions on the BIOS setup utility screen to change the boot order.
In this example the boot order can be changed using the + and - keys. Remember, your BIOS may have different instructions.
By using the + and - keys the example changes the CD-ROM Drive to the top of the Boot Order.
Using F10, Save and Exit, saves all actions and exits, or navigate to the Exit tab and save changes.

Note: USB drive does not appear as an option in the list, even though the computer has USB ports. If a USB device is connected to the computer before starting the computer and accessing this screen, the USB drive option will show in the list. Some computers display the USB drive option even when a drive is not connected.

The boot order is a priority list. For example, if USB drive is above hard drive in your boot order, the computer will try the USB drive, and if it is not connected or no operating system is present, boot from the hard drive.

If you need to disable secure boot to boot from a USB device, see this link: Disabling Secure Boot.
