Every time I transport my PC or when a power outage occurs, naturally, I turn off the power supply. However, when the system is set up again and the power supply is turned back on and plugged in, the first boot is always a double boot. The double boot does not occur after the first instance until I turn my PSU off and on again. This did not happen when the PC was first built. It's not a huge deal, but I would like to know whether or not this is an issue with the power supply or BIOS, or maybe even the M.2 SSD. Is anyone knowledgeable on this topic?
