    Hie, I have a experience a problem after power failure on my fedora 10 server. My server normally start in gui mode. But now after the power failure its displaying grub prompt. (The screen had this message:- GNU GRUB version 0.97 9639k lower/3664848k upper memory) {Minimal BASH-like line editing is supported. For the first word, TAB list possible command completions. Anywhere else TAB lists the completions of a device/filename.] then grub>.

    How do i recover my normally operating mode, or what are steps or procedures that i may take to return to my level 3 and 5 or the the gui.

    Normally grub reads its menu.list (or in some cases grub.conf) from the /boot/grub directory and displays a graphical list of boot options. Assuming that for some reason it cannot display these, it will default to a command line boot-loader.

    If I recall, you must tell it the boot partition on which it will find the kernel (partition 1 is 0, 2 = 1, 3=2 and so on) with the command "root (hd0,0)" - if your boot partition is disk 1, partition 1. Then you must tell it what kernel it is to boot with "kernel /path/to/kernel" - as it says, you can use TAB completion to help you find the name, it will probably be something like kernel /boot/vmlinuz-2.6.27.img or such.
    Then you need to pass it the options of what root filesystem it will be mounting after it has loaded the kernel (assuming that the boot partition and main partition are separate) this is done by providing the kernel with the root=/dev/hda2 parameter on the command line (again, assuming that your root partition is /dev/hda2).

    My grub knowledge is somewhat hazy, googling about grub booting would probably yield far more useful information.
