The helpdesk technician has been tasked to reinstall the OS on a desktop and has already inserted the OS install disk in the CD-ROM. Which of the following would MOST likely need to be configured within the BIOS to continue reinstalling the OS?

A. BIOS password
B. Flash BIOS for firmware upgrade
C. Boot sequence
D. Clock speeds

Correct Answer: C

To boot the OS from the CD ROM, you need to change the boot sequence to boot from CD ROM first. Normally, the boot sequence is to boot from hard disk and if it is unable to find boot files there, it will look for it in a CD ROM. After that, it will look into other places like a floppy disk drive and PXE boot.
