Hi,
We have server on MB S2400SC server board with latest BIOS, ME, etc. - S2400SC_EFI_BIOS02060005_ME020107328_BMC0127r9958_FRUSDR113.
Now, we want move from SATA RAID System drive to SSD NVMe drive - Plextor PX-256M8PeY , and install MS Windows Server 2016, but we get a some problems.
As I understood from manuals (and forums), to boot OS from NVMe SSD, MASS Storage option in BIOS should be set to AHCI mode, without RAID support. Ok, BIOS loaded default settings and the Mass Storage option set to AHCI mode, without RAID.
1. when BIOS switched into EFI boot only - EFI Optimized Boot = Enable, in this case, boot from EFI USB flash drive is stopped after several seconds, loading freezes. The same is happened when I boot from MS WDS using UEFI network stack.
2. when BIOS switched into - EFI Optimized Boot = Disable , in this case, we can boot from USB flash drive and produce the first part of the system installation. BUT! to boot from NVMe SSD we MUST to switch into UEFI boot mode only - EFI Optimized Boot = Enable , again. And in this case we have the same problem as in 1 para. I see Windows Boot Manager option in BIOS - Boot Options page , OS start loading, but after several seconds stopped, loading freezes.
Could you help us?
