[SOLVED] Motherboard won't recognize M.2 SSD

[felipeposada]

Does a HP SSD EX900 M.2 250GB work with ASRock AB350M Pro4 Motherboard? I installed one and my bios and Disk Management won't recognize it.

NVMe SSDs do not appear within the BIOS until Windows creates the system partition with the EFI Boot Sector. Your M.2 SSD contains UEFI driver information within the firmware. By disabling the CSM module Windows will read and utilize the M.2-specific UEFI driver during the Windows 10 installation.
