I recently installed Windows 7 on a new SSD, and after installation I entered the bios and changed to AHCI and then pc would not boot. I am really not sure what the AHCI is, but read that I need to change to it for best performance from my SSD. Also, when I enter "fsutil behavior query disabledeletenotify" into the command promt I get a zero value indicating the TRIM is enabled. I hope this makes sense. How do I make sure I am optimizing the SSD? I used this guide:

ahci is another type of drive system, and you will need to set to ahci before loading an operating system...
but then again motherboards just love to reject that setting and may only run with ahci turned off

Windows 7 comes with both sets of drivers, but only enables whicever type is set during startup in order to save time. It is possible to change, though as you discovered, it is a little more complicated than simply setting AHCI in the Bios.


Please be strongly advised the below steps involve changing registry settings and drive type, and therefore it is possible to hose your system and (Worst Case) necessitate a complete re-install.

Seriously - If you don't do those things you screw this up, be prepared for liberal doses of (good natured) Ridicule. ;) 


You have been Warned. :)
