Questions tagged [bios]

Questions about modifying the system's BIOS to make it fit Ubuntu's need, or questions about recovering Ubuntu after a BIOS modification. Note that questions about accessing the BIOS should not be asked.

The BIOS software is built into the PC, and is the first code run by a PC when powered on ('boot firmware'). When the PC starts up, the first job for the BIOS is to initialize and identify system devices such as the video display card, keyboard and mouse, hard disk drive, optical disc drive and other hardware. The BIOS then locates boot loader software held on a peripheral device (designated as a 'boot device'), such as a hard disk or a CD/DVD, and loads and executes that software, giving it control of the PC.This process is known as booting, or booting up, which is short for bootstrapping.

How do I enter BIOS

When I press the F2 key I can enter into BIOS before I change its OS (Windows 7) to Ubuntu in my Samsung 530U3C Ultrabook. But now I can't, it directly goes to Ubuntu. Can anybody help me?
