Editing Centos Minimal Installation (section)

===Prepare Disk Image and Copy to Disk on PC===

For installing Centos 6.5, USB keys can be used to install the desied ISO by using dd. 

<pre>
dd if=CentOS-6.5-x86_64-bin-DVD1.iso of=/dev/sdb
</pre>

When asked for media, select "Hard disk" and *the device* corresponding to the USB Key (make sure to select device and not partition). 

For Centos 7, there are issues with Windows tools transferring the Centos installer image correctly. Only use dd for Windows, or Rawrite32, or Win32 Disk Installer. If using a version of Windows newer than Windows 7, make sure you unmount the USB drive first (or format it before launching the disk copier) otherwise you will receive a "can't write to drive" error message. 

If using dd for Windows, run dd --list and look carefully at the list of NT Block Device Objects and use the one that looks like \\?\Device\Harddisk1\Partition0 where the description is something like "Removable media other than floppy. Block size = 512". Be very careful about which output device you pick or you may overwrite something on accident. The specific path will vary. 

It is not recommended you install anything past Centos 6.5 at this time, as only the latest version of Centos is ever supported.
