Hello, I have a problem. I bought my mom an SSD to an old computer with hopes to refit in the newer pc later, but since she needs the pc now, I tried to install windows with it. But I can't, because the SSD is not recognised. It doesn't show up in bios, nor in the install window. The strange thing is that a sata hdd works just fine.
In options there isn't an AHCI mode, maybe that is why it's not working? I can choose sata modes IDE and RAID.
SSD: Samsung 860 evo 500gb sata
Mobo: biostar p4m800-m7 a
The hdd that works: Toshiba DT01ACA100
What are my options? Is it possible to make the SSD work on this pc?

EDIT: The SSD works perfectly fine in my own pc (not the one I'm asking for help on).

Thank you in advance.
 
Solution
When in raid mode, you will probably need to enter the raid bios and set configure the drive as pass-thru or a single drive raid 1 array.
You would then choose RAID mode, as AHCI is just a subset of RAID. Just don't actually set up any array and attach the disk with the HDD disconnected, do a custom Windows install and as a first step delete all existing partitions on the drive.

Now if the drive is MBR it may not show up with a standard W10 install since it likes GPT. In that case you can change the drive to GPT. Provide more details about what you are doing and have tried and I can give you an approach to do a proper install.

For example if it was used in W7 MBR mode, then the quickest was to make it GPT is with a diskpart command.
 
I tried to install windows 10, but the logo was there for like 5 mins and nothing, the install didn't come up, so I tried win7. The install came up, but it said there were no drives or something like that. Then I put the SSD into my own pc, tried to install windows and it all went fine. Tried another sata cable, tried my own ssd in mom's pc, didn't work. My hdd worked though. It started loading my old windows 7 on the hdd, though it was taking too long (like 10 or 15 min) so I shut it down. Probably wouldn't have run because of lack of drivers and stuff.

The drive is completely new, bought it today. Well it was, I tried to install windows 7 on it with my pc already.
I just don't understand why would the hdd work and ssd wouldn't on the exact same settings. The hdd says its sata 6gb, so sata 3 right? Also when booting it opens some kind of hardware manager or info tab which has like ide 1 none ide 2 none ( or empty, can't remember right now), CPU temp and CPU fan speeds. I believe it says ide 1 cd/dvd drive and some kind of ide slave and master, like 6 of them, all empty.

I'm not really knowledgible in bios stuff, so I will take a picture tomorrow, since I already put the pc in the corner and disconnected all the cables.

Is it possible that the motherboard doesn't support ssds?
 
When trying to install W7 it would have become MBR partitioned. Attach it to your W7 computer again and open an elevated command prompt (right click run as admin) and the type:
diskpart <hit enter>
list disk <hit enter>
select disk n (where n is the ssd in question from the list numbers, choose carefully) <hit enter>
clean <hit enter>
convert gpt <hit enter>
exit <hit enter>

Then attach the SSD to her machine (before shutting it down to attach the SSD change bios to RAID but don't setup an array) and disconnect the HDD. Insert USB installer stick and boot up, install to the only available drive (SSD).

If you would rather use W7 then just stop after the clean command and attach the SSD alone to her computer and install the OS on there -- you cannot install it on your machine and then move it.
 
She has windows 10 at work, so she prefers win 10. I just tried windows 7 because the installer surely works, as I have installed before from it and my Win7 hdd started loading.
So I plug in the SSD into my own pc and do all the commands if I want to install windows 10 on hers?
Her computer is not usable, because the hard drive failed a few years ago.
I have the exact same ssd for myself and a 1tb hdd, so I'm confused at the part "attach ssd to her machine (before shutting down change bios and remove hdd)" windows did not load at that pc, it just showed the windows 7 starting animation and it was taking very long, so I turned it off.

I will send some pictures of the bios settings and other screens tomorrow when I turn on the pc. Thanks for the help thus far.
