Which is the fastest booting operating system

Change the boot order in the BIOS

The small program is stored in a non-volatile memory and is supplied with the necessary energy by the computer battery even when the mains plug is pulled out. The task of the BIOS is to make the computer functional after it is switched on in order to then initiate the start of the operating system. We would like to use a test computer to show you how to get into the BIOS and how to change the boot sequence.

This action is required, for example, to not start the computer with the operating system from the hard disk, but from a bootable CD / DVD. For example, if nothing works anymore, it can be a rescue CD or if you want to load a new operating system from CD / DVD onto the PC.

Step 1: Enter BIOS

Since there are different BIOS manufacturers, the access is a little different. Immediately after the start, you actually get information from every manufacturer about which key press or key combination is used to grant access to the BIOS. The most common keys are "Del", "Esc", "F2" or "F10". The keyboard shortcuts are very often "Ctrl + S", "Ctrl + Esc", "Ctrl + S" or "Ctrl + Alt + Esc". If there is nothing for you here, just google the Internet and ask for "BIOS access - your model". There should also be a note in the manual for the PC or mainboard.

Step 2: Set the boot order

After you have pressed the corresponding key or key combination, the BIOS start screen opens after a short time. Usually the first tab (often "Main") at the top left is activated by default. To change the boot order of the computer from hard disk to CD / DVD drive, navigate with the right arrow key on your keyboard to the "Boot" tab or something similar. Use the "Enter" key to open the register. Under the "Boot Settings" navigate with the arrow keys to the entry "Boot Device Priority", "Boot Sequence" or similar and press the "Enter" key. If your CD / DVD drive is the first in the following window, you do not need to change anything. However, if the system hard disk is at the top, press the "+" key on your keyboard until the CD / DVD drive takes the first position.

Step 3: Apply changes

Since there are different BIOS variants, the navigation in the masks can also vary. Please note the information on the masks either at the bottom or on the right-hand side of the screen. Exit the input mask with the "Esc" key and press the "F10" key. You will now be asked whether you want to apply the changes. Here you mark "OK" with the arrow keys and press the "Enter" key. The PC reboots and first of all checks your CD / DVD drive for a bootable disc. If you want to boot from the hard drive again quickly, simply change the boot sequence using the method just described.
