Can someone suggest how I can change my on board Intel RAID to AHCI without reinstalling windows?

I have a P5Q-Premium, and until recently I had 4 300GB disks in RAID 10, two of them failed recently so I decided to get an SSD and forget RAID all together.

If I change the BIOS option from RAID to AHCI, I get Windows BSOD at boot, I don't think it is an issue with the boot sequence, I ran BCDEdit and repaired everything (nothing to repair).

I have the RAID management software installed, I'm thinking I should uninstall it, uninstall the devices in device manager, reboot, change to AHCI and hope that Windows boots and loads new drivers, will this work?
OS is Server 2008 R2 SP2

TIA
 
I had to do this to get AHCI working with my P5Q-E board. Edit: just saw your OS, and my instructions were for Win7, but you may have to do something similar.

To resolve this issue yourself, enable the AHCI driver in the registry before you change the SATA mode of the boot drive. To do this, follow these steps:
Exit all Windows-based programs.
Click Start, type regedit in the Start Search box, and then press ENTER.
If you receive the User Account Control dialog box, click Continue.
Locate and then click one of the following registry subkeys:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
In the right pane, right-click Start in the Name column, and then click Modify.
In the Value data box, type 0, and then click OK.
On the File menu, click Exit to close Registry Editor.
Click to expand...
