Boot Media preparation

Download:

• Download Boot ISO from (x86_64): (http://linuxsoft.cern.ch/cern/centos/7/os/x86_64/images/boot.iso)

(in some browsers you may need to right-click on the media link, then choose "Save")

Create bootable CD:

• On Linux systems:
    execute the following command: cdrecord dev=X,Y,Z boot.iso (where X,Y,Z is the SCSI bus/device/LUN of your CD writer, can be seen with cdrecord -scanbus command)
    or use a graphical frontend like xcdroast.


• On MS Windows systems:
     Use Nero Burning ROM or similar in raw mode.

Create bootable USB drive:

• On Linux systems:
    execute the following command: /bin/dd if=boot.iso of=DEVICE (where DEVICE corresponds to your USB device, can be found using: dmesg after connecting the device)
      Note: Always use the device name (ie: /dev/myusbsdz) not device partition name (ie: /dev/myusbsdz1) as argument to of= option.
      Note: Make sure to choose right /dev/.. device: the dd command will destroy the content of the target .. which could be your system drive ..


• On MS Windows systems:
     Use dd for Windows
