This howto shows the steps needed to copy a Fedora/Redhat/Centos ISO to a usb stick such that it can be booted from and install the OS.
The steps are as follows:
The simplest way is by using dmesg
This is the output of dmesg on my laptop , run immediately after plugging in my usb stick
The output of dmesg shows that a USB device was pluggined in. Also we can see that the device was given the name /dev/sdc and it has two partitions /dev/sdc1 and /dev/sdc1.
fdisk -l | grep sd
From the above, I can see that /dev/sdc is the correct one because it is the one who's size matches. It can not be /dev/sda or /dev/sdb because those are too big to be my usb disk.
sudo dd bs=4M if=ISOFILE.iso of=/dev/sdc conv=fdatasync
replace ISOFILE with the name or full path of the isofile you downloaded. Go make a cup of coffee , it will take some time depending on the speed of your USB device.
