How To Turn On AHCI After Windows Install This tip can be a real time saver for system builders (if you do not know what AHCI is, this tip is not for you). Have you ever installed Windows 7 and forgot to enable AHCI in BIOS? In the “old” days you were told your only option was to re-install Windows. Not so! The following registry edit will enable AHCI after an install. Go to: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/msahci Then change value of Start to 0 (that’s a zero), and AHCI will work. :) Tip of the hat to MaximumPC Magazine

"...to fish fine and far off is the first and principle rule for trout angling." ~Charles Cotton (around 1674)

The trout do not rise in the cemetery so you better do your fishing while you’re still able ~Sparse Grey Hackle

There is no greater fan of fly fishing than the worm. ~Patrick F. McManus

A nod from me.

I have used this a while a ago on a multiboot machine.

 

Switching Sata to AHCI (For Hackintosh purposes)

and Win7 and WinVista were fine thanks to the routine above.

WinXP needed a repair install.
