If the motherboard BIOS is set to 'legacy' mode, then at boot you may see that the 4K VD will be reported by the LSI MegaRAID BIOS, but you will see the '0 are handled by BIOS' message. This indicates that the VD is not being exported to the operating system by the controller, and thus you will not be able to boot from that VD. This is happening because the 'legacy' BIOS setting of the motherboard doesn't understand the 4K sector size. 'Legacy' BIOS supports booting from disk drives with the industry standard 512 byte sector size.
A única solução é alternar para unidades 512e ou para alternar do BIOS para a inicialização via UEFI.
