    If you pass 1 or single to kernel of any Linux distro, Linux will boot up in Single User Mode.

    Try single instead of 1.

    Vickey,
    the grub file is only top part, its not complete. Do the following,
    Code:
    cat /boot/grub/menu.lst > ~/grubmenu
    You'll find a file by name grubmenu in your home directory. Post that here. Again, is the screen completely blank after selecting from grub or it shows some error messages?

    Btw, when you are posting a file's content or output of a command which is very long, use 'code'.

    P.S. - Smilies are there coz, you enabled smilies in your post and any character combination that relates to a smile will be shown as a smily

    # is the entry saved with the command 'savedefault'.

    I hope this is what we are looking for. I tried to copy the file (/boot/grub/menu.lst) in the same directory i.e grub but ended up with some error then followed ur instructions , but y can't I copy the file in grub itself. It directory permission seemed ok. And also last time when I posted the contents of the menu.lst it was only the top part , how to select the entire file in VI??
    And yes I almost forgot that there are no errors displayed on the screen.
    Only if I could understand the man pages

    We can't help you unless we check exact error.
    Have you tried to replace 1 with single and removed keyword quiet and splash in kernel line?
    In case it doesn't work this time, try 3 instead of single.

    Sample kernel line :
    Code:
    kernel		/boot/vmlinuz-2.6.27-7-generic root=UUID=43f615be-2e45-46ce-9c83-24bff792cbdd ro 3

    I think problem is something else as it hangs after the grub. It simply hangs . I ll try doing the text mode (3) lets see.

    Removing quiet and splash keywords will display necessary inforamtion and error message, if any.
