Setting up and SSD

I installed a Samsung EVO SSD in my computer. The Samsung program says I need to enable AHCI mode, but this can cause my drive to fail to boot. I looked it up and found a Microsoft fix I would need to do before switching.

https://support.microsoft.com/en-us/kb/922976

My Drives are set to "Legacy mode."

I think I should do the Microsoft fix and go into the BIOS and switch to AHCI. I want my SSD to be my boot drive and I want to image/clone the current HDD so that the SSD boots up without reinstalling everything. Then the HDD will be for storage.

Does this sound like the right thing to do? Any tips or advice?

I'm sorry I forgot to put more information.

I have an Optiplex 780 MT Intel core 2 Quad 3.0 GHZ with Windows 7 Pro 64 bit.

I tried using the fix it and then switching to AHCI in the BIOS. My computer did not boot. I tired switching back to "Legacy," but that did not fix it. I ended up using Dell DataSafe to get it back up and running.  I thought the Fix it was supposed to make it so that my computer still booted after I switched to AHCI.

My SSD wants to to enable AHCI. How do I do that and keep my computer booting?

My plan is to use Samsung Magician to clone the HDD to the SSD, then make the SSD the boot drive.

I could also install windows from the Dell disk, but I would still have to enable AHCI.

Another concern I have is Dell DataSafe. I looked it up and some people have problems using a clone of a drive that has Dell Datasafe. Should I uninstall it and then reinstall it on the SSD?

I think this might be my problem. I found this discussion of the same problem at:

http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/changing-from-raid-to-ahci/4c94f678-6bd1-48a6-b871-8872c841023a?page=1&tm=1436405429659

"I believe I have the solution to your problem and I verified it against a Dell machine that has similar controller with your machine. Changing from AHCI to RAID,http://support.microsoft.com/kb/922976 fix will work.  

Changing from RAID to AHCI, you need one more step. Msahci driver requires Atapi.sys miniport to be loaded during boot as well. So you need to change theStart value to 0 for both of the following entries in your registry. You can use regedit.exe utility. 

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\msahci
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\atapi

Or you can also simply run the below command lines in an elevated window.

REG ADD HKLM\System\CurrentControlSet\Services\msahci /v Start /d 0 /f /t REG_DWORD
REG ADD HKLM\System\CurrentControlSet\Services\atapi /v Start /d 0 /f /t REG_DWORD
"

What do you think?
