GEEK_ASUSIt looks like the laptop waited for me to write the previous comment and then laugh at my face by messing the boot again 😄. I suspect the reversal is due to a Windows update two days ago but can be a coincidence (the listed updates were for Bluetooth and and Windows Intelligence). By the way, I also noticed that Windows has a hard time connecting to my online storage drive. For the few days that the laptop was booting normally, I connected to the drive as fast as I clicked on it after Windows start; but before and after that period, I sometimes needed to wait minutes until the drive becomes available.
Please try to update BIOS and Windows Update to the latest version.
