The term "boot options subscreen" refers to a menu or screen that appears during the startup process of a computer or electronic device. It is a component of the device's firmware or operating system that allows the user to modify certain settings related to the boot process.
In this subscreen, users can access and modify various boot options that govern how the system starts up and initializes. These options include but are not limited to the choice of boot device, boot order, and boot mode.
The boot device option allows the user to select the storage device from which the system will boot. This can be the internal hard drive, an external USB drive, a CD/DVD disc, or a network location, depending on the available devices and their configuration.
The boot order option determines the sequence in which the system attempts to boot from different devices. Users can prioritize the boot devices according to their preference, ensuring that the system checks each device in the desired order until a bootable device is found.
Boot mode refers to the configuration that determines whether the system will boot in Legacy BIOS mode or the newer Unified Extensible Firmware Interface (UEFI) mode. This setting is important for compatibility with different operating systems and hardware.
By accessing and adjusting these boot options in the subscreen, users can troubleshoot startup issues, optimize system performance, or install a new operating system, among other tasks.
