Why each option
Losing power during a BIOS upgrade is the most common and critical cause of BIOS corruption, as it interrupts the flashing process, leaving the firmware incomplete or damaged.
Applying BIOS settings in the incorrect order might lead to incorrect system behavior but does not inherently corrupt the BIOS firmware itself.
The BIOS upgrade process involves rewriting the firmware on the motherboard's non-volatile memory chip. If power is lost during this critical operation, the flashing process is interrupted, leading to an incomplete or corrupted firmware image, rendering the system unbootable.
Installing the OS before applying a BIOS upgrade is merely a suboptimal order of operations but does not corrupt the existing BIOS.
Imaging the system after a BIOS upgrade is a standard backup procedure and has no negative impact on the BIOS.
