Find the Correct USB Device Name

There are two ways to find out the name of the USB flash drive.

  • The first one is use lsblk (strong recommend).

    boyang:~$ lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda           8:0    1   3.8G  0 disk
├─sda1        8:1    1   242K  0 part
├─sda2        8:2    1   2.8M  0 part
├─sda3        8:3    1 859.2M  0 part /media/yanboyang713/PVE1
└─sda4        8:4    1   300K  0 part
nvme0n1     259:0    0 465.8G  0 disk
├─nvme0n1p1 259:1    0   512M  0 part /boot/efi
└─nvme0n1p2 259:2    0 465.3G  0 part /

  • The second way is to compare the output of the fdisk -l command. Both example at the below.

boyang:~$ sudo fdisk -l
[sudo] password for yanboyang713:

Make a bootable USB using DD ddbootableusb

On Unix-like operating system use the dd command to copy the ISO image to the USB flash drive. First find the correct device name of the USB flash drive (see above). Then run the dd command.

[yanboyang713@manjaro] ➜ ~ sudo dd bs=1M conv=fdatasync if=/home/yanboyang713/Downloads/proxmox-ve.iso of=/dev/sda
