So, I am planning on installing a SSD as a primary boot drive in my system, but I had a few questions that I'd like to clear up before I start. I plan on doing a clean install of Windows 7 , and I've been reading that enabling AHCI mode in the BIOS needs to be done before you install the OS. I have a Gigabyte EP45-UD3P motherboard. In the manual, it says that I have to add the AHCI drivers to the windows installation so that the OS will recognize the hard drives correctly (after I enable AHCI in the BIOS). I know that this had to be done for XP, but is this still necessary with Windows 7? I guess my question is, what is the chance that Windows recognize my hard drives in AHCI mode if I just enable it in BIOS and then install the OS normally?
