    Hi @Themiya
    Same happened to me last year with my a515-54G originally configured as RST-Optane SATA mode UEFI, that I changed to AHCI on recommendation as I don't have Optane or SSD. Apparently Bios flipped back to factory settings after installing Windows and also "No bootable device found". I took out my HDD and downloaded all data to another PC using an external USB case, then reformatted the external HDD and reinstalled it in the laptop. Then turned in the laptop to Acer service who reinstalled everything free of charge, I never touched the Sata mode (UEFI) again and have been running it for over 1 year without any issues (on Windows10 21H1 latest build now). Hope this helps
