Can someone please explain how to trigger a command line only boot of CentOS 7 from a USB boot stick?  I want to boot the terminal only and then use the normal CentOS 7 terminal to swap out the graphics card drivers using yum.  That way I will be able to subsequently use the same boot stick to boot the full version of CentOS 7 incuding the gnome gui.Currently, when I try to boot using the usb stick, the gnome gui cannot be loaded because an attempt to use the graphics card throws a driver error that I want to address by replacing the drivers as above.  Here are the steps that I have taken so far, which are failing: 1.) Insert USB boot stick2.) Turn on power for pc3.) Press esc every second until a list of options appears4.) Press F9: Boot Device Options5.) Three options appear:     a.) OS Boot Manager (UEFI) Windows Boot Manager    b.) USB Hard Drive (UEFI) PNY USB 2.0 FD     c.) Boot From EFI File6.) I selected USB Hard Drive (UEFI) PNY USB 2.0 FD7.) The computer tried to boot CentOS 7 but crashed and gives the     Dracut Emergency Shell instead of the normal terminal.  The Dracut      shell does not have all the same commands as the normal terminal.  Pressing esc, F2, F12, or del repeatedly did not stop this on a repeated tries either.What do I need to do differently?
