    Reinstall 11.10 to 10.10

    Hi. I have a little problem. I have installed Windows 7 on my laptop and Ubuntu 11.10. I want to uninstall 11.10 and install 10.10, so i formated partisions of 11.10 and install there 10.10, but the grub menu doesn't show any list of operating systems when i start my computer. The grub show me "no such partitions" and grub's command line. I can't run any system. Please help!

    Grab your live-cd, boot from it, open a terminal, and do
    Code:
    sudo grub-install /dev/sda
    sudo update-grub
    Assuming your hard drive is listed as sda and not hda, sdb, etc.

    Really, on the one day I don't have an operating system in my pocket?

    Make it easy on yourself and keep a copy of Rescatux around.

    Unless of course your livelihood depends on knowing how to install grub from liveCD by memory.
