Proper Steps To Upgrade My Server 2008 R2 Machine From HHD To SSD

I'm working on upgrading a server's hard drive from a standard HHD to an SSD drive. I have cloned the drive with a program called "EaseUS Todo Backup Free 8.6" (which I think does a bunch of extra steps than just cloning the partitions) and that seemed to work fine. The issues that I'm running into is my server currently is running a hardware RAID 1 array (MIRROR) and I have decided to move to a software RAID so that I can use the TRIM function with my new SSD drives.

The issue is when I set my BIOS from RAID to AHCI windows refuses to boot and ends up at a STOP screen (BSOD) with error code 0x0000007B.

I'm trying my best to resolve this issue and have been looking all over the web for answers. What I ended up finding was that my server (Intel X38ML) currently has the RAID drivers installed and NOT the IDE drivers OR the AHCI drivers that I actually need. So this BSOD is all I get when I change it from anything but RAID. Both IDE and AHCI settings in the BIOS give me this BSOD.

I have been to this site to grab the drivers I thought I needed as suggested by another site, but those did not work for me. So I tried to grab older drivers specific for my board (I guess) from this site which is also an Intel site, but those did not help either. Everytime I try to install these two drivers I get the following...

My device manager currently looks like this...

I'm looking for something like this in the end...

Any ideas? How can I load those AHCI drivers on my OS to be able to switch to AHCI in the BIOS? Or am I going about this the wrong way?

UPDATE

I thought it was worth adding to the original question... I have already completed the required registry edits to enable AHCI.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
- Edit REG_DWORD called "Start", change value from 3 to 0.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV
- Edit REG_DWORD called "Start", change value from 3 to 0.
- Note this key did not exist on my server so I took no action.
