Netinstall CentOS 6.3 from USB disk

From Windows:
Use Ubootnetin:





From Linux :
If you want to install CentOS from USB disk you simply need to download the netinstall.iso (which is analog to the boot.iso that Red Hat provides).

It seems they made this netinstall.iso a hybrid one. (can be booted from cd and from disk (USB))

So you can just dd it to your USB disk.

To check what device udev made for your inserted USB check last dmesg output

 Then do the dd:

dd CentOS-6.3-x86_64-netinstall.iso /dev/sdd
What the netinstall iso does, is booting the anaconda installer. It does not contain any repository. In the installer you have to select which repository you want to use. For example: http://linux.mirrors.es.net/centos/6.3/os/x86_64/
