grub
 

Hello Guys
One question please
/vmlinuz-2.6.9-34.EL ro root=LABEL=/ rhgb quiet 3 and boot the system.
what kind of information each of the /rhgb and /vmlinuz subdirectoris include

Neither of those are subdirectories. You can verify this by looking in /boot and seeing that there are no directories with those names. vmlinuz is the kernel image and "rhgb" stands for "Red Hat Graphical Boot". Do some googling for more info: http://www.google.com/search?q=%22Re...ient=firefox-a
