I’ve been fighting with this the past week and I haven’t had much luck, so I’m hoping that someone can be of assistance to me. I fully assembled the build, powered it on and it boots into the BIOS just fine. However, whenever I try to boot into Ubuntu on the SSD it makes it past the GIGABYTE logo and freezes with a single underscore. I have another system in which I can boot from the SSD just fine in (HP z420 Workstation motherboard, same spec as above.) I am able to boot into a live usb of Ubuntu, but the system automatically restarts after 10 minutes, or so. Any suggestions?

Could the memory be populated wrong? Seems like a lot of choices from looking at that board.

3

my guess is CSM vs EFI boot

I’ve triple checked the manual for this board and I’m positive it’s populated correctly. I’ve even have removed all but one module.

5

Whenever I disable CSM no boot options are available.

I was able to resolve my own issue. Ultimately, I was able to boot into the OS with the SDD installed in a external drive enclosure. For some reason after doing this and reinstalling the drive I was able to boot. Doesn’t make an ounce of sense, but she’s alive.
