Since such a warning message appears, if the data in the USB memory to be used remains, move it to a PC etc. before doing it.

When the writing is completed, a notification sound will sound, so this completes the USB installation media creation.

PC USB boot After inserting the USB installation media into the PC you no longer need, start the PC and then press F12 (depending on the PC model) to enter the Boot Menu.

Select USB to enter the CentOS 7 installation screen
