Hard drive detected by BIOS but not by Windows 10 Pro Solved

Question

Hello,
I just finished building my new PC (all new parts) but I have a problem Windows does not detect my hard drive while the BIOS does... Even going into "disk management" nothing is there, only my SSD...
I've looked at plenty of tutorials but nothing works, it just won't show up...
If someone could please help me.

Hello,

If everything is brand new... including the disks... the HDD comes delivered completely blank, you need to start by FORMATTING it... then it will be recognized in Windows.

I assume you have installed Windows on the SSD and that it is working??

Go to the disk management... (Windows key + R) and type

diskmgmt.msc

in the window, you should see your two disks there.

Right-click on your disk No. 1 (the SSD should be No. zero) and choose "create a volume"...
Go back to it and choose format, let it do its thing, then restart the PC, you should see your disk..

You can upload screenshots to the site cjoint.com, create the link and copy it here so we can see your image..

Oh yes, for sure, you only have one disk...

The other one might be poorly connected... although not if it appears in the BIOS. What are the references for this Seagate..?.... Check the connections again, especially pushing the connectors in firmly...

Otherwise, in the BIOS you might have forgotten to validate something... like validating the SATA
Validating the second disk

I recommend installing the dedicated formatting software... "Minitool partition wizard free" https://www.minitool.fr/gestionnaire-partition/partition-wizard-accueil.html

You'll see if it detects your disk and can format it... if not, you need to look in the BIOS for something that hasn't been validated... You can also try switching the SATA port on the motherboard to connect your disk to a different one..

I think your SSD is logically on the first port, and this one should be on the second.

I unplugged and plugged it back in several times, nothing more and nothing less...

In the BIOS, everything seems to be enabled, but I'm a novice, so to me, it's good

On the software you recommended, it only detects my SSD, so I can't format my hard drive...

As for the connections, my SSD is on SATA 5 and my hard drive is on SATA 2. Does it change anything if I am not on the first one with my SSD?

I’ve sent you a link with a picture of my BIOS regarding the SATA. To me, everything is fine...

I hope I can find the solution because I've been looking for one since 2 PM, but nothing... I've asked for advice in several Discord groups, and no one understands, not even me...

Hello
have you changed the SATA port to see?
otherwise we're going to try with Diskpart
Press the keys " Windows+X "
then press the " A " key
in the window that opens, type Diskpart
then list disk
see example

Hi,

I have a Z490 UD AC, and I don't understand why you have this issue

If you were using a SATA M.2 SSD, there would be more SATA ports taken into account, but if you're not using one...

My 4 HDDs are detected properly.

Put your SSD on SATA 0 and your HDD on SATA 1

Have you updated your BIOS? (F6b) https://www.gigabyte.com/Motherboard/Z490-UD-rev-10/support#support-dl-bios

I do it through the BIOS, even the USB stick in FAT32 in the white socket.

Another thing, do you have the latest version of Windows 10 (20H2) X64?  https://www.microsoft.com/en-us/software-download/windows10

In Advanced Mode, Settings, I/O Ports, Intel RST Configuration, Is it like this?    Use RST Legacy OROM but it's only for my RAID, you don't need that.

Here is the tool to create the media (8GB USB key) to reinstall Windows

[French France] https://www.microsoft.com/fr-fr/software-download/windows10

If you already have the Windows ISO file, you can create your USB key with Rufus

Boot from it using the PC's Boot Menu (The F12 key)

Choose "Custom installation" (Not an upgrade)

Delete all system partitions and create a new one (This will erase the data).

In principle, this is the best way to install Windows to date.

What if we disconnect the SSD to only leave the HDD... and you try to install Windows on it... what would that say..??

And where does the Windows ISO file come from...?? Is it the one provided by Microsoft..??

We have to say that all this is new and hasn't worked yet... Could it be something else..??

And if we put another HDD in its place, is there the same error..?

Hello everyone, I have good news, it's all good, I've solved the problem!!!!

So it was indeed the hard drive that had a problem because I bought a new one from another brand (Toshiba P300) and now it's good, it's properly detected by Windows, it's ready for use!!!

I thank you for the help and the time you dedicated to me. Problem solved!!!!!!!!!!

It's a strange thing... to be recognized in the BIOS and not in Windows...???

fabul · Answer

The firmware was recognized, but the disk itself was not supposed to give or take any information.
