Is the problem from (1) ASUS UEFI BIOS, (2) Win10 Fall Creator Update, or (3) firmware on the Crucial SSDs? When I initially setup my R5E it had no problem detecting and allocating a Samsung 850 PRO.

During installation an NVMe driver must be added in order for the OS to detect the drive properly. As a result, the Windows 7 installation media will not detect the SSD.That is how UEFI works, unlike MBR the disk itself is not the boot device, the EFI partition is the bootable device which points to the bootloader on the disk. When the install finishes boot to your bios and make sure that Windows Boot Manager is listed first in the Boot order list. Go ahead and install Windows 10 in UEFI GPT mode.


I have the newest BIOS firmware 1.24, released 18 of June. When I switch back to the standard disk that followed the laptop, this disk gets detected immediately. However, it is not detected during boot, BIOS or any post-installation of operating systems. I just bought a new SSD disk (Intel X25-E) and inserted into my SL 300 laptop.
