Attempting to install Ubuntu 16.04 Server onto a newly initialised disk. Using UEFI, and a 4.5TB / partition. After installing without issue, on rebooting, the server will not get past Grub.
- New Supermicro Server
- Hardware 6 x SSD RAID 5 – 4.5TB Virtual Disk
- BIOS Fully updated
Selection of UEFI Virtual CD which is Ubuntu 16.04 Server. NOTE – I did chose the UEFI Virtual CD rather than the highlighted non UEFI as shown in the screenshot (i realised after i took the screenshot)
Ubuntu default guided partition layout, non LVM, completely unmodified. Confirmation of partitions, including ESP is present.

Try booting with supergrub dvd/cd. It may fix the problem with grub. This has sometimes worked for me in the past. Failing that just reinstall again.
