dracut warning:unable to process initqueue

[dongrerohan421]

Hello,
I installed fedora 17 KDE in virtual box.

Now i am trying to install nVidia Drivers in fedora 17.
I followed these steps:
#lspci |grep -i VGA
#yum install akmod-nvidia xorg-x11-drv-nvidia-libs

installation successfully completed..

To remove / disable nouveau drivers from kernel initramfs:
#mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img

#dracut /boot/initramfs-$(uname -r).img $(uname -r)


And after rebooting it shows:-

dracut warning:unable to process initqueue
dracut warning:/dev/disk/by-uuid/ddceda30-bc89-43df-89cd-12ee2e32104b does not exist

dropping to debug shell
dracut:/#


Please help me to start my OS regularly..

Thanks in advance.
