I'm trying to install Fedora 18 on an HP DL 180 G6 with no luck so far. Please don't suggest installing/using Centos as we have a requirement to use Fedora 18. I have tried using two different USB flash drives with various iso images (DVD full, netinstall, LiveCD). Images were all created using Fedora USB Creator and Unetbootin. The server has no DVD drive (I'm in process of obtaining a USB DVD drive to attempt to boot directly from DVD or CD).
I don't know what could be the problem. The server already has Fedora 16 installed and everything works properly.
All attemps of booting from USB flash drives end with message:
dracut-initqueu[345]:Warning: Could not boot.
dracut-initqueu[345]:Warning: /dev/root does not exist.
Entering emergency mode

After entering journalctl
I found some strange entries about a firmware bug :
Could this be a hardware problem? I can boot the installed Fedora 16 install and all logs are showing clean and everything works like a charm. The problem only starts when I'm trying install Fedora 18.
Should I be worried about the firmware bug noted in the logs?
Maybe I should update the firmware on HP DL 180?
Is there any other reason that I can't proper install Fedora 18 or even properly boot the installer or live distro?
The server is in a remote location (~300KM) and I only have KVM over IP access. There is an admin from the remote datacenter that is helping me with this but all he/she can do is connect the USB flash drive or put a DVD in a drive.
Maybe some of you had some similar problem and have already resolved this.
Maybe I should run some more diagnostic tools (I'm now doing the memtest and so far all ok).
Sorry for my English (Yes I know it's terrible )
EDIT
Booting with the default video driver also with no luck:
