The “boot menu” allows you to temporarily boot from a different device, rather than your standard C drive. This is useful when you wish to boot from a CD, USB flash drive or separate hard drive but do not want to change your basic input-output system settings. This feature is rooted in the motherboard’s BIOS, which means the key combinations, which are used to enter BIOS, may differ among models of Compaq Presario computers, now produced by HP. Some models may not offer this feature, which requires you to enter the BIOS for boot changes. Writer Bio
