I have tried both boot from USB and DVD.
On booting, I get the menu
Code: Select all
Install CentOS Linux 7 Test this media & install CentOS Linux 7 Troubleshooting-->
Same happens when selecting "Troubleshooting-->" and then from the next menu "Install CentOS Linux 7 in basic graphics mode".
Judging from the blinking light on the USB stick or rattling from the DVD a lot of files are read from the installation medium, but then things get silent and appear to be stuck. Nothing happens on the screen, stays dark (black) with cursor (underscore) in top left corner.
