Step 1: There are many good reasons for booting your computer from a USB drive. For instance, if you want to try out another operating system without disturbing the main hard drive on your computer, then installing the new OS on an external drive is a great way to run the system through its paces and decide whether you like it.
This approach will offer you the flexibility of being able to run both operating systems on your computer. However, before you can boot the new operating system from the USB drive, you will need to change the boot order for your computer in the system BIOS.

Press the "Delete" key as the computer performs the "Power On Self Test" (POST) to enter the BIOS area of the computer firmware. The POST performs a diagnostic of components on the motherboard and does a cursory check of the hard drive, memory and processor. The POST only lasts a few seconds; therefore, press the "Delete" key quickly. Enter the administrative BIOS password if prompted to do so. Once you enter the correct password, you will see the main BIOS screen. Use the right-arrow key to navigate to the "BOOT" menu option at the top of the screen, and press the "Enter" key. Press the down-arrow key until the cursor is on the "Boot Device Priority" label. Hit "Enter," and press the down-arrow key again to highlight the "1st Boot Device" option.

BIOS on a Fujitsu C-Series LifeBook b> Resetting the BIOS system of a computer can help revitalize the computer's usage. Oftentimes computers are "broken" when they are misconfigured in the BIOS menu of the computer before it boots up. When the settings are improperly selected, the BIOS prevents the computer from working properly. To get the computer back up and running again, the BIOS needs to be reset. The Fujitsu LifeBook C2111 has its BIOS system located on the motherboard beneath the keyboard.
Turn the Fujitsu laptop over with the computer powered off. Remove the AC adapter and push the battery release latch in and pull the laptop battery out of the Fujitsu. Remove the screw holding the hard drive in place and slide the cover off of the laptop. Remove the two screws underneath the cover that holds the hard drive onto its bracket.

Remove the small screw above and to the left of the keyboard with the Phillips screwdriver. Push the keyboard toward the screen until it disengages. Fold the keyboard over the screen and rest it there with the keys facing the screen. You will now see the motherboard of the Fujitsu C2111. Locate the small, round lithium-ion battery on the motherboard and remove it. This is the BIOS battery that stores all of the settings and password of the BIOS when the computer loses power. Hold the power button in on the computer to drain the BIOS system and leave the battery out of the laptop for at least 30 minutes. Place the BIOS battery back into the motherboard and reattach the keyboard. Tighten the keyboard screw that you removed earlier, and turn the Fujitsu back over and reattach the hard drive along with the covers for the hard drive and RAM.
