Hi, is this on DGX Spark Founders Edition or an OEM variant?

Have you checked whether you’re following the requirements and steps in this guide?

I would recommend trying to create the USB flash image again, it may not have been created correctly. Please follow the instructions linked by a149952. If it still does not work then please open a ticket with Customer support

Thanks,but still not working.I’m going to open a support case

@xinyuan.huang is the kernel present in the root directory of your USB recovery drive?

The GRUB menu entry is:

menuentry "FastOS USB Install" {
    linux /vmlinuz nouveau.modeset=0 console=ttyS0,921600 console=tty0 sbsa_gwdt.action=1 pci=pcie_bus_safe
    initrd /initrd
}

and vmlinuz and initrd should be in the / directory:

elsaco@nevada:/run/media/elsaco/BOOTME$ tree -L 2
.
├── boot
│   ├── boot.cat
│   └── grub
├── efi
│   └── boot
├── efi.tar.xz
├── fastos.partaa
├── fastos.partab
├── fastos-release.txt
├── fw
│   ├── ec_fused.cap
│   ├── ec_nofuse.cap
│   ├── set_cap_flag.bin
│   ├── socfw.cap
│   ├── tpm.cap
│   ├── usbpd.cap
│   └── yukon_ec_nofuse.cap
├── initrd
├── sgdisk.txt.example
└── vmlinuz

6 directories, 15 files

Not sure if it matters but the current system I’m using, not a DGX Spark, has all the kernels in the /boot folder with the execute enable bit set. The one on the recovery disk is not marked executable.
