Hello,
Following the acquisition of an SSD, I installed Windows 10 on it without deleting the old Windows 10 that was on my hard drive (I understood that it wasn't the right way to do it).
So, even after redefining the boot priority in the BIOS to the SSD, it boots from the hard drive. However, if I select Windows Boot Manager (SSD), it does boot correctly from the SSD.
How can I simply boot from the SSD? I've read other posts but I feel like there are always some differences with my issue and I no longer want to mess around with my PC.
Thanks in advance!

Hi,
Start up on a working Windows and take a screenshot of the disk management, maximized window. We'll see what we're starting with.

So, here's the situation explained: Windows on disk 2 is installed in UEFI mode, on a GPT disk. That's why the entry "Windows Boot Manager" appears in the BIOS. The screenshot was taken from this U10 installed in UEFI. And under UEFI, it can only boot from the Windows Boot Manager entry, since the EFI partition manages the booting.
On the other hand, the two other disks (0 and 1) are in MBR format, and they are set to boot in Legacy mode (or in CSM mode in your case since the option is enabled). If this option is disabled, only disk 2 will be able to boot.
In summary, you need to know what exactly you want to do, knowing that one of the Windows installations is incorrectly set up compared to the other. Furthermore, both disks 0 and 1 are bootable.. Why?

Super thanks!
Actually, I had Windows 10 on my 1TB HDD originally. In the meantime, I purchased a 500GB SSD and installed Windows 10 in UEFI on it, without uninstalling the Windows 10 from the HDD (I was planning to wait for a 2TB HDD to move my files and format the one that has Windows).
I don't know if everything is clear haha, but in any case, everything is normal then?
And I just want to be able to boot from the SSD while keeping all my other HDDs to store all my data. I would also like all my HDDs to have only one partition for storage, and there seem to be system-reserved partitions that look unnecessary.

Hello everyone!
You put an SSD for Windows and later you plan to put a 2TB for your data to replace your 2 HDDs.
Right now, it’s a mess.
Partitions that serve no purpose.
A Windows installed not in UEFI, but with CSM and in legacy (emulation of old BIOS)
A possibly badly made installation key
...
You say you installed in UEFI but that's not the case.
Did you mess with CSM and enable legacy???
And you can't connect the SSD to the first port, so it becomes disk 0, which is cleaner.

Hello,
No, I'm planning to use my 3 HDDs for storage and my SSD for Windows.
Yes, I'm well aware that it's a mess, which is why I'm asking for help :')
The key was created using the Windows 10 Media Creation Tool.
And I did start the installation in UEFI, well that's what it said, I had the option to launch the installation in either of those two modes.
Okay, I'll take note of that for the connection.
Thanks for your help!

Yes, it seems that it is in UEFI as there is a UEFI partition.
With the message image 10, I don't understand why you have the BIOS in CSM and Legacy.
Did you reset these settings afterwards?
If you disable CSM and set the BIOS to UEFI (plain UEFI), does Windows on the SSD boot properly?
And in that case, are your 2 HDDs recognized (at least in disk management)?

I always have to boot from Windows Boot Manager (SSD...)
Yes, as mentioned earlier, it seems that's the case.
The main thing is to know if your PC starts up alone on this Windows Boot... which is actually your SSD, since you would only have the SSD for testing (2 HDDs disconnected).
After that, it seems there is a misunderstanding regarding your claim that your SSD doesn’t boot or doesn’t boot directly.
Because it's somewhat unclear,
does the PC in UEFI boot with just the SSD or not?
If so, do you see your 2 HDDs (remember to reconnect them ;-) )?
...
If it boots from the SSD alone, and the HDDs are visible, we will confirm that the 4 small partitions on the 2 HDDs serve no purpose and can be removed.
If nothing works, start over point by point.
Because a PC with that much storage should be as clean as possible before adding too much more.

Basically, here’s the structure you’d need on your PC.
Let’s say
Bios in UEFI only
(and with no CSM or legacy enabled)
Disk 0
bootable SSD under UEFI, with Windows on it and the software
Disk 1
HDD for storage
And to avoid cluttering the SSD, you should modify the library paths under Windows.
Basically, everything you download, save (documents, photos...) will go directly, by default, to the HDD instead of saturating the SSD.
Disk 2
The other HDD you will use for "manual" storage as well as possible backups.
It’s good to check the health status of these HDDs beforehand, with this software for example:

Better safe than sorry. ;-)

Sure, thank you very much! So first, changing the order of the disks is fine.
I've already started creating shortcuts, I definitely didn't want to clutter the SSD as you said. So I put shortcut files on the SSD pointing to the HDD.
Thank you very much anyway, I'll try to check the health status, but shouldn't I check that after formatting them? Just to have only my data and not the installation folders of the old Windows 10.

I don't know what you mean by shortcuts, but it's really the folders in "this PC": documents, pictures, downloads, music, videos... well, everything that is used for storage, that needs to be moved like this:
http://www.windows8facile.fr/deplacer-bibliotheques-sur-autre-disque-partition/
WARNING, very important, you have to create the folder that will receive the data before moving.
(don't just dump everything on the entire HDD but on a folder)
The test is immediate, because if an HDD has an issue, it'll need to be replaced, so there's no point in wasting time emptying and formatting it.
If the PC in UEFI boots Windows from the SSD properly, and the HDDs are recognized
Then depending on how they're organized, H and G, if it's just data not mixed with the old system, you can keep everything and only delete the unnecessary partitions (the 4 small ones).

Yes, that's what I did actually :D
Oh right, there needs to be a base folder, got it. That’s fine on that side then.
Ah, I didn't understand, okay, but when I unplug the HDDs, they're not visible in the BIOS, and I can still boot. So I can delete the partitions. Anyway, I reinstalled Windows by unplugging the HDDs as I was advised.
In any case, according to the software, all my HDDs are rated as "correct."

So should I completely reinstall Windows? Format the SSD and reinstall? Or is a repair sufficient?
And afterwards, can I reconnect the HDD without issues, even though it still has Windows on it?
only keep the SSD connected to the motherboard
to ensure a fresh start
after installation
restart with only the SSD
if it's okay
then reconnect the HDD afterwards
check the UEFI/Legacy boot options.
Was the installation of Windows 7 on the HDD done in UEFI or BIOS?
It is recommended to have a UEFI installation to take advantage of the startup performance and security.
For this, the partition table of the SSD must be in GPT, the BIOS emulation option must be disabled, and fast boot enabled.
For BIOS emulation on Asus, it's the "CSM" option; for others, I don't know, but it can easily be found online.
Hope this helps.
PS: I’m sorry for the mistakes, they are ingrained in me.
As for the HDD, I don't remember. However, for the SSD, I formatted it in GPT before installing Windows 10 in UEFI. But I didn't check if the BIOS emulation is disabled and fast boot is enabled. If that's not the case, do I need to reinstall Windows according to these settings?
Thanks for the help anyway :)
