Fedora 10 isn't booting, give "unable to access resume device"
I had fedora 10 install updates overnight and when I came back in the morning I turned on the monitor but there was not signal coming from the video card although the computer was on. I restarted. After Grub flashes on the screen it gives me this message

loadkeys: /lib/kbd/keymaps/i386/qwerty/us.map.map:4:
cannot open include file qwerty-layout

unable to access resume device (/dev/VolGroup00/LogVol01)
mount: could not find filesystem '/dev/root'

Thank you.

It seems your system either got suspended or hibernated. How did you restart it?

I held the power button on the computer until it turned off. I couldn't shutdown normally because the monitor wasn't receiving a signal from the computer.

When the system is suspended or hibernated, there is no signal to the monitor - that has been suspended... In such cases, you need to use the key-press combination required to unsuspend it, or just press the power button very quickly. It might take a minute to come back since if hibernating it has swapped all running processes and memory to disc. At this point, try shutting the system down and restarting from a cold boot. If that doesn't work, then you are going to need a recovery disc and fix the problems found. I had to do some cleanup and recovery recently on my CentOS system when we had a lengthy power failure and I didn't get everything shut down before the UPS timed out. I could only boot into single user mode, but I was able to fix the problems pretty easily.

So should I boot it up right now, and once it gives me those message while booting i should press the power button quickly? and after that what happens? should I just restart after that?
