The BIOS boot sequence determines the order of the devices the computer will attempt to boot from. If the sequence is incorrect or has changed, the system might attempt to boot from a non-bootable disk, leading to the "Invalid System Disk" message. Checking and adjusting the BIOS boot sequence is a primary step to ensure the system tries to boot from the correct device.
