Hi guys and gals. I will try and be as brief as possible and this issue has been annoying me for the last few hours.

So I purchased an SSD today, Samsung EVO 850 250gb to be specific. Now when I got home, I had no actual boot disks as my buddy had one of mine, So formatting and re installing was kind of out of the question for now. So I search around on the net and found a few OS -> SSD migration tools. The particular one that I used was the Paragon migration tool. Anyways, the transition went well and the files transferred successfully. Afterwards the program prompted for me to go into the BIOS and change from IDE to AHCI. Once in the BIOS I noticed two things. 1) The SSD is not recognized in the MSI BIOS that I have and 2) every time I attempt to go AHCI, my boot fails and the REPAIR screen pops up each and every time.

So My questions are:

1- Why does it show my SSD as an active E: drive under my computer after the successful migration of files, while the drive itself is not available in the BIOS? or at least it is not tagged as Samsung 850 evo as it was prior to the migration when I attempted to make it the primary boot.

2-Why does AHCI not work when I attempt to switch it on?

3-How do I fix these issues? And given that I have both the HDD and SSD now, how can I tell which one will run my games and other applications, if both the drives have the same files on them?


I thank you so much for your time, I am hoping somebody can chime in and help a newbie out here :)

3-

After a good clone, you should install the cloned ssd into the sata port that the original boot hdd was in and then boot normally. Try this without the HDD installed. Then if everything is OK, add the old hdd and do what you want with it.

Crystaldiskmark is a good and free app to test the speed of your ssd.

You need to be in AHCI mode before windows in installed. But there is a work around. Set your comp back to where it was and and install the SSD into the port that the original boot drive was. And with out the original drive installed and see if you can boot. Then:

In the registry, navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci

Then right-click on the word Start on the right-side and click Modify. Change the value to “0” and click OK. Exit Regedit, reboot the system, and change your sata controller to AHCI, save & exit then boot into Windows.

After your comp is up and running OK, you can install the old boot drive in another sata port and have access to it with all your files and etc on it. Can delete windows files and more to clear up space.

If still no go, you might have to install windows from scratch with only the SSD installed at first, then drivers and etc. Then install the old boot drive.

Okay so, just as the replies came in I managed to find a similar post and got the file changed from IDE TO AHCI under the HKEY_LOCAL as you just now suggested. My question still is, how do I know if my pc is taking advantage of the SSD. Does having both drives active under 'my computer' suggest that YES it is working? Or does the SSD still have to be set as the priority boot drive under the BIOS?

Mind you, I am not super savvy with this stuff, so breaking it down for dummies would be lovely :)

So I just unplugged my HDD and kept the SSD plugged in. And while in the bios, it now read the SSD as the primary. However, when proceeding to boot I got a momentary blue screen and the pc just booted up again. When I plugged the HDD again I was prompted to repair the pc using the windows tool. So, to even bypass this blue screen and auto restart I have to take out the CMOS battery each time and revert back to IDE mode or the pc will not even boot. What now? QQ

Firstly, thank you for sticking around and checking up on my post, seriously. And before I resort to what you just mentioned I figured I would update my progress now to see your perspective if this is now working properly. So, I went under Regedit and set both values to "0", restarted my pc and running in AHCI now works without any errors. Does this now suggest everything is all and well or is there another way to determine that?

ps. Loads don't feel super fast, however, they weren't super slow to begin with. Perhaps I will check up on some Path of Exile load times to see if anything has changed.

Thank you again, awaiting a reply.
