How can I fix my A2 error with my SSD?

Greetings dear community!

About a year ago I made a similiar thread asking how I can fix my problem with the A2 error and the black screen when I try to boot my PC with the SSD attached: http://www.tomshardware.co.uk/answers/id-3177280/ssd-error.html. However, I have not followed up on it since then, which is my own fault.

PC Specs:
Motherboard: MSI Z87-G45 gaming
GPU: Msi gtx 770
CPU: Intel core i5 4670 3,4 ghz
Ram: 8GB
OS: Windows 7

The thing is, I have become very tired of knowing that my quite expensive 250gb Samsung SSD has been "rotting" in my cabinet for like 3 years now, not being used at all. So, I figured it was to finally do something about it rather than "hiding the problem" and trying to forget it.

Contextual information: In short, after I got my SSD, I installed windows 7 on it, but somehow failed to install drivers on it. Afterwards, I decided to try to use Samsungs "Data Migration Software" (which comes with the SSD as free software) to migrate everything from my HDD to my SSD after I had cleared up plenty of space on the HDD. However, after the software asked me to restart my PC once the migration was finished, I have been getting the A2 error each time I have tried to boot with the SSD attached, making me unable to enter BIOS. However, i have no problems booting with my HDD or getting into BIOS, as long as my SSD is not attached.

I thought that I had perhaps "ruined" my SSD, but this theory was "busted" a friend of mine, as he succesfully formatted it on another PC. Actually, he said that he had no problems with booting the PC with the SSD attached. This must mean that the problem is not with the SSD itself or it being "ruined/malfunctioning",but rather my motherboard


Here's a list of things I have tried to do so I could boot with my SSD and bypass the A2 error:


So what do you guys suggest I should do in order to get my SSD in working status? One thing could be to update my BIOS, but is it safe? Are there other possible solutions I could try?

I really hope to get my 250 gb Samsung SSD working once and for all, because I'm sick of long load times, slow start time and crazy stutter and lag spikes in games such as Rising Storm 2: Vietnam and DayZ.

Thanks in advance! :)

  1. Could you list your full specs please.
  2. Did you plug the SSD into another SATA port as well?

    Do you have anything connected to the MSATA port?
    Is the bios setup as raid ?

    You can use live update 6 software from msi to update your bios within windows.
    https://www.msi.com/Motherboard/support/Z87-G45-GAMING.html#down-driver&Win7 64

    It will also check for driver updates for your system

    You can find it by clicking on link above /selecting your op system (win7 64) then utillities .

    I have my HDD connected to a normal SATA port as far as I know.
    I don't know if the bios setup is "as raid". Don't even know what it is.

    I'm late with my response, but thank you so much for your help man :) ! Your suggestion has finally made be able to use my SSD. And actually, bypassing the A2 error and making the SSD function was much easier than I thought. I simply had to update it by downloading a "bios update file" through the website/link that you provided and putting into a USB. Then I simply had to put it into the PC and the BIOS would recognize it. And after updating the BIOS, BOOM, NO A2 error and I could easily install Windows by selecting UEFI mode in BIOS. Again, thank you very much :) This means a lot to me as I've had this Samsung 840 EVO 250 GB SSD for like 3 years without using it due to the A2 error - but now I can finally use it :) and I love its speed!
