Question Automatic repair couldn't repair your PC error when trying to use AHCI mode

[Nightmare837]

I wanted to install dual boot Arch Linux, but the SSD was in Optane With RAID mode. I have to change it to AHCI to install Arch but Windows won't open in AHCI mode. How to make Windows 10 work with AHCI mode without reinstalling Windows?

My laptop is Acer AN515-55.
