Boot loop on the BIOS

Solved

Hello,
I just bought new components (motherboard: B560-A gaming wifi, i5 10400, and graphics card Asus rog Strix 3060 ti) and once these parts were installed, I turn on the PC and it takes me into the BIOS the first time. From there, I loop in the BIOS no matter what I do. I can't get past this step and access Windows which is installed on my M.2.
If anyone has one or more solutions, I’m all ears because I’m out of ideas.
PS: it's impossible to choose which SSD to boot from, but when you dig through the BIOS, you can see that it recognizes them.

    Hello

    Which version of Windows? What was the configuration before?
    Did you do any preparation before changing the motherboard?

    When starting with new hardware, you shouldn't leave all the drives connected. If you have or want to install Windows on the M.2, disconnect the others.
    Then there's a problem because apparently the controller on the board shows RAID; you need to make that disappear. It's AHCI or UEFI or something else, but not RAID.
    If you have any option for IRS (Intel Rapid Storage) set to enabled, you need to disable it.
    First do that, then we'll see.

    Hello,

    Generally, for different hardware it is highly recommended to reinstall Windows.

    Otherwise, the problem may also lie with the BIOS, are you in legacy or UEFI? SSD partition table?

      I also tried reinstalling Windows; since I don't have a CD drive, I'm using a USB stick, but it won't boot from it.

      For the BIOS, I'm not really sure; there is a ton of information, and I can't quite find what I want.
      I know that by default, it shows "Other OS" or UEFI Windows for the operating system type. I've tried both modes, but it doesn't change anything.
      I have no idea about the partition table of the SSD.

      I changed some settings and now at startup, I get a Bootmgr missing error when my USB drive is inserted; otherwise, I go directly to the BIOS
      I changed the system type to UEFI
      And I enabled CSM
      - boot device management: UEFI option ROM and legacy
      - boot from network device: legacy only
      - boot from UEFI storage device only - boot from PCI-E/PCI device: UEFI only


      On the Asus BIOS home screen, it shows storage information:
      RAID:
      Samsung SSD 860 Evo M.2 (500GB)
      Samsung SSD 840 series 250GB
      ST2000DM001-1ER164 (2000GB)

      So it sees them

        It's better to disable CSM; it's intended for older partition tables and older Windows versions, although Windows 10 is still compatible with it, but not Windows 11.

    Just a small correction, the processor is an i5 11400F and not 10 400.

    I disconnected all the drives except for the M.2 that had Windows on it. I also managed to switch it to AHCI instead of RAID.
    I'm still in the BIOS. It doesn't recognize the Windows partition installed on the USB drive to start a new Windows installation and keeps sending me back to the BIOS.

       He doesn't want to take the Windows partition installed on the USB drive.


      What do you mean by Windows partition...?

      On the USB drive, you should have the ISO burned with a software that is capable of extracting the ISO (it's still best to use a DVD...), then in the boot order, set the USB drive as the first option. You can also press F8 at the start of the boot and choose the USB drive.

    That's it, I made it!
    I reformatted my USB stick and reinstalled the Windows installation files, and it finally booted from the USB stick.
    Now everything works ????
    Thank you all ????
