Failing to boot after fresh Installation of Windows 10
Yesterday I decided to freshly install windows on a new SSD (via a bootable USB). Since then I have been encountering problems regarding the setup of Windows. I always get to the point of the f...

The bluescreen only persisited while using my old SSD. Because of me not being able to fix it, I tried reinstalling windows via an USB - fresh installation. However my during the installation process the SSD is recognized, but afterwards when the computer restarts it won’t recognize my SSD anymore in the UEFI Bios, even though I started the installation while in UEFI Bios. (Double checked a 1000 times). However: the SSD shows up in UEFI + Legacy boot mode. This led me to believe that my UEF/Bios may be outdated (even though I used it the last time 3 days ago with no problem). What I believe is, that even though I install in while GPT formatted, it changes it to MBR? Or is my motherboard faulty?
(It all works fine until the first restart of the system while fresh installing). Even thou I unplugged the usb too and so on. What I think it is, is that it fails to detect it as an boot option in the boot order section of the UEFI/Bios after the installation of windows. As a sort of test I plugged in my other ssds to check if they are also not recognized - they are not, only if I turn on CMOS. Which makes me wonder because some of them aren’t event a year old, no chance on them being to old for UEFI.
of course, this is not a solution, but sometimes it is worth giving this computer to the service,
they install daily new hard drives and reinstall the drivers from the computer manufacturer's website, so I suggest you take this step.- Btw I found someone having the exact same issue as me, maybe his point of view is easier to understand than mine:
Hello guys!
I'm having some troubles here.
I'm trying to do a fresh new install of Windows 10 on my SSD.
One important thing to note is that my Mobo has an option "Support for Windows 8/8.1" that forces me to use UEFI only. If i don't activate it, then i can use Legacy+UEFI mode.
So, when i'm in UEFI only mode (Window 8 support activated) i can install Windows 10 on my SSD, BUT, after the first restart, it doesn't work because it's not "seen" by UEFI. It simply doesn't show up in the bootable devices list (although it had been well detected by my USB Windows Installer).
However when i'm in Legacy+UEFI mode (Windows 8 support deactivated), the SSD does showup in the devices list since it's only "seen" by Legacy (it doesn't have the UEFI prefix to its name, like some other devices do), but i then can't install Windows 10 on the disk (telling me that my Mobo doesn't take it in charge -> because support is deactivated or because SSD isn't as "UEFI") or can't continue the install (for the same reasons).
So i'm a bit stuck. On one side i can install Windows but can't boot on my SSD, and on the other one i can't install it.
I've been searching for hours, seen a lot of topics similar (yet slightly different) to this, and couldn't find any answers that would solve my problem.
I have in my BIOS AHCI Sata mode activated, i'm in UEFI only and my SSD is formated and in GPT (i made sure of all of that)
I think it's also worth mentioning that the SSD is well detected by the Mobo as it shows in the list of connected SATA ports. I also tried another cable, didn't change anything, and i believe the SSD is working fine, since it has always been.I also found such a clue "
If you want to install the system on a GPT disk then you need to delete all partitions.
If you want to install the system on the MBR disk then you need to enable the Legacy BIOS boot option in the firmware."
