Final answer:
To decrease the boot up time, you can change the boot order in the computer's BIOS settings.
Step-by-step explanation:
When a computer takes a long time to boot up, it can be frustrating. In this case, the computer is checking the CD drive for the boot disk first and then checking the hard drive. To decrease the boot up time, you can change the boot order in the computer's BIOS settings.
The BIOS is a firmware that controls the basic functions of a computer, such as booting up. By accessing the BIOS settings, you can specify the order in which the computer should check for the boot disk. You can change the order so that the hard drive is checked first, which will speed up the boot process as the computer won't waste time checking the CD drive when there's no bootable disk present.
To access the BIOS settings, you typically need to press a specific key or combination of keys during the boot process, such as F2, F10, or Del. The exact key or combination may vary depending on the computer manufacturer. Once in the BIOS settings, look for an option related to the boot order or boot sequence. Change the boot order so that the hard drive is the first device to be checked, save your changes, and then exit the BIOS settings. After doing this, the computer should boot up faster as it won't spend unnecessary time checking the CD drive first.
