DGX Spark boots to either black screen or NVIDIA logo and I cannot access GRUB

Hi everyone,

I am having a boot issue on my DGX Spark and would appreciate any help.

What happened:

  • I believe I ran sudo apt update
  • After restarting, the system no longer boots properly
  • It now goes to a complete black screen
  • I cannot get back into Ubuntu at all

What I can access:

  • I can access BIOS/UEFI
  • I cannot access GRUB

What I already tried:

  • I looked online and saw that on DGX Spark, Left Shift + Insert might open GRUB
  • I tried that multiple times
  • It does not work for me
  • I am using a wired keyboard

Current status:

  • Every boot ends in a black screen
  • I am unable to log in or reach recovery options

Questions:

  1. Is there another reliable way to access GRUB on DGX Spark?
  2. Is this likely caused by an Ubuntu/NVIDIA boot issue after package updates?
  3. What are my best recovery options from here?
  4. If GRUB is inaccessible, is USB recovery or reinstall the recommended path?

System:

  • DGX Spark
  • Ubuntu 24.04

Any guidance would be really appreciated. Thanks.

You will need to use “sudo apt dist-upgrade” or “full-upgrade“ or going to the Dashboard to do upgrade from there.
Your system might have ended up → half-upgraded
To go to the GRUB menu PRESS&HOLD “Shift” and “Insert” button together during boot up
