Deleting a boot from the BIOS (basic input/output system) involves removing an entry that specifies a bootable device from the computer’s boot order. When a computer starts up, it checks the BIOS to determine which device to load the operating system from.
Deleting a boot option can be necessary for various reasons, such as removing an old or unused operating system, resolving boot issues, or preventing unauthorized access. It’s important to note that changes made to the BIOS can affect the computer’s startup process, so it’s crucial to proceed with caution and consult the motherboard or system manufacturer’s instructions if needed.
