OS Boot from USB problems - Dell XPS 15 9500

Hello,

I am trying to install NixOS from a USB drive.

After trying both minimal and GNOME installs I can not get past Stage 2 in the boot process. I have tried nomodest, copytoram, and debug to no avail.

I have seen problems in with Dell/Nvidia hardware, but am unsure how to proceed to modify the iso file.

I don’t believe it is the USB drive. My hardware is Dell XPS 9500, with Intel i7-1075 CPU, Geforce GTX 1650 Ti Mobile GPU. I have Secure Boot Off. SATA operation is set to AHCI and it is booting with UEFI. \

I hope I provided enough info to be helpful (at least initially).

Thanks
