Windows 7 – Re-configure SATA drive to use AHCI

I installed win7 with the SATA drive running in Standard IDE mode, and I now
wish to run it in AHCI.How do I go about doing that.
I’am using Gigabyte EP45-UD3R mainboard
help please.
Answer #1
Your best bet is to re-install your Win 7 with AHCI turned on in bios
Knw it’s a pain in butt – but best way
Answer #2
Ever heard of the phrase “If it ain’t broke,Don’t fix it”? Your HDD is not gonna run any faster in AHCI mode.
AHCI is only useful when using an external ESATA HDD (hotplug support),Back to the original question,Only from
the BIOS,Refer to the manual:

Do note that by doing this you’ll effectively screw up your OS and would have to reinstall!

Nah. It takes only a single registry edit.
Run>regedit
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msahci
Set the Start value to 0, reboot and go into the BIOS and change the configuration to AHCI and Windows will boot fine.

Interesting,But how will this work if the OS lacks the needed driver for the particular SATA controller?

I’ve never seen a desktop that AHCI wouldn’t work out of the box with Windows 7 and (most of) the laptops that have this issue don’t have IDE mode to begin with.
