invalid magic number




When booting to CentOS bootable USB. The way I made the USB (on Ubuntu 17) is:



  1. Download CentOS-7-x86_64-DVD-1708.iso

  2. dd if=CentOS-7-x86_64-DVD-1708.iso of=/dev/sdc status=progress

  3. Booted to the boot menu, chose the USB drive, then chose Install Centos 7

How do I do this?

          Your command seems okay, just try few things, double check device name, make sure device is not mounted while writing and at the end try running sync command.




           dd if=CentOS-7-x86_64-DVD-1708.iso of=/dev/sdc ; sync
