Command
dd
On a Linux system, you can use the
man1/dd.1.html) command to create a bootable USB flash drive that contains the DGX OS
software image.
Note: To ensure that the resulting flash drive is bootable, use the
device bit copy of the image. If you use other commands to perform a simple file copy of the
image, the resulting flash drive may not be bootable.
Ensure that the following prerequisites are met:
‣
The correct DGX OS software image is saved to your local disk.
For more information, see

The USB flash drive meets the following requirement:
‣
The USB flash drive has a capacity of at least 16 GB.
‣
This requirement applies only to DGX A100: The partition scheme on the USD flash
drive is a CPT partition scheme for UEFI.

2. Obtain the device name of the USB flash drive by running the
manpages.ubuntu.com/manpages/bionic/man8/lsblk.8.html)
lsblk
You can identify the USB flash drive from its size, which is much smaller than the size of
the SSDs in the DGX software, and from the mount points of any partitions on the drive,
which are under
/media
In the following example, the device name of the USB flash drive is
lsblk
~$
NAME MAJ:MIN RM
sda 8:0 0
|_sda1 8:1 0
|_sda2 8:2 0
sdb 8:16 0
|_sdb1 8:17 0
sdc 8:32 0
sdd 8:48 0
sde 8:64 1
|_sde1 8:65 1
~$
