Hello,
Before doing this new installation I was already on Windows 10 but my OS was an updated version of Windows 7, then Windows 8. I had no issues but I wanted to do a completely fresh installation of Windows 10.
I therefore decided to format my SSD on which my OS was installed. I first had to manually convert my SSD to GPT in order to install W10 because it couldn't do it automatically. I then created 2 partitions on my drive before installing W10 on one of them (I mention these two things even though I'm not sure if it can help to understand the problem)
The installation itself went smoothly, but it was at boot time that I had an issue: indeed, I can't boot in "UEFI Hard Disk" mode; when I select this mode, it takes me to an EFI Shell screen with a "device mapping table" message (https://imgur.com/BwXKgEE
To boot Windows, I need to choose the "Windows Boot Manager" option (https://imgur.com/zKrSn1e in the "UEFI Hard Disk Drive BBS Priorities" category of my BIOS (https://imgur.com/LpEK5vB And with this option, I can boot but I don't have the normal Windows 10 startup animation (It's as if the startup animation and my motherboard logo had merged). That said, after this everything goes well and the system runs normally. But for me, this way of booting is not normal and I think it could cause me issues.
I've tried several times to reinstall W10 but I've encountered the same problem every time.
Could someone enlighten me? Thanks in advance!
Another info: if I try to boot in "Hard Disk: Samsung SSD 840 PRO" mode (my SSD) I get a "Reboot and select proper boot device" message.

Hello
The boot mode on "Windows Boot Manager" is the normal startup mode.
This is the one to use.
Now, I don't really understand this story about animation...

There are 3 kinds of people: those who can count and those who can't.-
Hello, and thank you for your response!
Is this really the normal mode? I didn't have this option to activate on my old W10 installation, that's why it seems strange to me.
As for the animation, here's a GIF to make it clearer ^^ : https://imgur.com/LXUV5By
The screen with the username disappears just after it appears and I go straight to the desktop. -

Yes, yes, it only happens once, it’s probably the GIF being cut a bit short at the end that gives this impression. The user’s blue screen doesn’t even last a second and I go directly to the desktop afterwards.
Indeed, when I disable the fullscreen logo, the animation displays normally with the Windows 10 logo.
So it’s perfectly normal not to be able to boot directly from UEFI Hard Disk without the Windows Boot Manager option? Same for the Hard Disk mode that doesn’t boot? -
Booting on Windows Boot Manager is a feature of the UEFI BIOS.
It uses the hidden partitions of the hard drive to start faster...
This is the "normal" boot mode.
To boot from a non-GPT disk, you would need to choose hard disk.
UEFI hard disk, it must be, I suppose, a non-Windows GPT disk..
Not all BIOS have these options... -
