Hi @shahizat ,

It’s not clear what you did to get into this situation…was this an apt full-upgrade or a dist upgrade, or something else?

If you contact NVIDIA Enterprise Support they can help get this figured out.

Hi @ScottEllis, the issue was solved by reinstalling GRUB. Unfortunately we don’t have active service support for DGX2. We have for A100. Anyway thank you for your reply.
