Hello; My first post. I normally run Win7 from a mechanical HDD. I recently added an SDD for another operating system and changed my BIOS to configure SATA drives to AHCI. WIN7 is still on it's original HDD. Everything I've read about win7 and AHCI mode is more than a year old. Is there an easy method that will allow WIN7 to live on an AHCI-enabled HDD? Would it be better to reinstall Win7 onto the HDD? Mobo is an ASUS M4N98TD EVO. Please advise.
