Hello, I just received my DGX Spark yesterday and everything was working perfectly. I installed a 65GB LLM, but after rebooting, the system never fully started up again. It gets all the way to the GDM login service, shows everything as “[OK]” in the boot messages, but then just hangs there indefini…

Following this post, I just used the same USB but this time instead of connecting through hub, I connected directly to DGX and it worked. [image] System Recovery - Failed to mount after 10 attempts DGX Spark / GB10 I waited for the fix overnight (thank you to …

This is absolutely frustrating. Just got mine this afternoon. Not booting… just black screen. I have been waiting over an hour…😡

@ashreaperone , I agree, tried even reaching out to their support team as always they suggested to post here and hope atleast here, we will get some response.

Hi, How did you create the bootable USB drive? We have our own tool to do it, did you follow the steps shown here to create it?

@aniculescu yes, I followed this guide and at step-6, they mentioned to select USB drive under “Boot Override” but I don’t see USB drive. I have only two options under boot override, UBUNTU (Samsung) and UEFI - PXE IPV4 realtex PCIe 10 GBE family contributor

Please try to create the USB boot again. If it still does not work, you may need to try a different USB stick

The boot failure occurs specifically at the GDM service after installing a large AI model. The system shows all services as [OK] until GDM starts, then hangs in…

Just a heads-up: It looks like in the DGX Spark Recovery Image, the CreateUSBKeyMacOS.sh script was moved out of the usbimg.customer/scripts folder, but the path inside the script wasn’t updated. The script still references /usbimg.customer/../usb instead of /usbimg.customer/usb, which causes it to…

You can try accessing the system remotely via SSH. If you can connect would you be able to collect the complete output of journalctl and attach it here, or send it to us? If you can also run sudo nvidia-bug-report.sh and collect the log file from that, that would also be helpful.

Hello @aniculescu I am attempting to perform a factory recovery on my DGX Spark following the official documentation at https://docs.nvidia.com/dgx/dgx-spark/system-recovery.html .
