I have read a lot about this and everyone says to boot in IDE then go into regedit and change msahci and pciide to 0, then reboot and change to AHCI mode and it is suppose to fix the problem. But that doesn't seem to work for me. They are both 0 but when I try and boot from AHCI I just get stuck on like an endless reboot and it won't work. I just installed a new Samsung SSD. Does anyone know why the regedit fix works for everyone else but not me?

Did you try doing this?

Boot In IDE, do this registry tweak, THEN change to ACHI:
