I posted a similar problem sometime last week...but a little has changed(mainly I can access my files now):
I recently performed the auto upgrade to Ubuntu 10.04 and upon restart of my machine I am presented with 3 screens. The first is a simple "GRUB loading". The second is "mount: mounting none on /dev failed: no such device". The third screen is a series of initializations, i.e. /dev/sda1: clean, (number of files), (number of blocks)
*setting preliminary keymap...
and so on until it hits the line:
*checking battery status
at which point it will cease loading until i press the power button. The next thing that occurs is it kills all the processes it just initialized and shuts down the computer.
I read that this is likely a problem from loading the wrong kernel and I can get into my files (using a boot 9.10 boot key). The problem is I don't know what files to change in order to get my system booting the right kernel.
Thanks in advance,
