    Probably corrupted windows startup. Have you pressed alt + f10 before the Acer logo?

    Change it to AHCI (described below how) and try to boot. 
    Go to BIOS screen, move to Main tab, press Ctrl+S buttons together, press F10 to save and exit, AHCI option should be available in Main tab. 
    Please click "Yes" if I have answered your question.

    Try to start in safe mode. In case it doesn`t boot either you have to try windows recovery.

    Do the following:
    a) change the sata mode rst with optane again;
    b) then, press alt + f10 before the Acer logo;
    c) you should find an option that enables safe boot;
    d) after entering windows by safe boot, press windows + r and type msconfig and enable safe boot on windows itself.
    e) then, change sata mode to ahci again in the bios.

    Well best will be if you isntall fresh windows copy, it would take less time  and you have already resseted it to factory settings so you will not loose any data from the after the reset moment(ou already wiped it out with the reset process).
