When you buy a computer, the default settings in the computer’s BIOS generally tell the computer to boot to the built-in hard drive first. This allows your computer to read and boot to the installed operating system. Occasionally, however, you may need to boot to a disk instead. For instance, if you need to repair or reinstall the operating system on your Acer Extensa 5210 laptop from CD, you must override the computer’s setting to boot to the hard drive to boot to the installation CD instead.
