Moving HDD to SSD - Bios ACHI/IDE Help

Hardware Hub Build a PC

Hey there,
So I am thinking of buying an SSD to use as a boot drive in partnership with my current WD 1tb Caviar Blue HDD, which would be used as a storage device. I understand that if I cloned the hdd to the SSD using something like Samsung EVO software, I would need to set the SSD to the first boot priority.
However, I see that you need to change the SATA type from IDE to ACHI in order to get the ssd to work. I also see that you need to change some things in the registry to get ACHI to work and boot (link here)
From the site:

Exit all applications
Go to the start screen and type in regedit.
If you see the UAC (User Account Control) dialogue box, just click continue.
Locate the the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\
Locate the Error Control entry which should have a value of 3. Right-click on the entry name, select Modify, change the value from 3 to 0 and click OK.
Open the StartOverride folder and locate an entry named 0 with a value of 3. Change the value to 0 by following the procedure in step 5.
Restart and enable AHCI in your system BIOS

So. Do you do these steps ^ before or after setting the SSD to the #1 boot priority? And do you do them before or after setting the SATA type from IDE to ACHI in the bios?

Thanks.

Or alternatively, would this method be easier to do on the HDD:
(Run msconfig (right click far left bottom corner of desktop then left click run, type msconfig).

Click boot tab, mark safe boot, restart, change to AHCI in BIOS, boot, Windows boots in safe mode.

Run msconfig again, boot tab unmark safe boot, restart PC.

PC works fine. Don't mess with regedit you only need to boot in safe mode to fix this, very simple.)

Question: Cam you run a HDD on AHCI? Would this method be suitable to do, then set the bios to ACHI, then clone the hdd onto the ssd and then set the ssd to boot priority?

There is an option in the samsung migration software to turn on AHCI. No need for diy registry editing.
Install ssd, run migration - turn ahci on, reboot into bios, change to ahci mode & ssd to 1st positon on the boot list, restart, do cartwheels.
Otherwise with another migration tool - install ssd, run migration, do registry hack, reboot into bios - ahci on & change boot order, reboot, do handstands.
Always nice to start with a fresh install of the os but as long as your happy with how healthy your os install is then migration is very easy especially with the samsung app.
Best of luck with it all mate.
