My Ubuntu crashed yesterday and after rebooting the grub rescue showed up. I've never used grub before but when I tried ls look like there are only Windows partitions there.

grub> ls
(memdisk) (loop0) (hd0) (hd0,msdos2) (hd0,msdos1)

I also tried booting from live CD and use fdisk. However there is no ubuntu partition listed. I am newbie and don't know what I can do next. Please help. Thanks in advance.

First of all you should stop using this harddrive alltogether. While booting into Windows should be relatively safe, you should better not have any writing access to this drive.

Next get your hands on a Live-CD, for example the disk that you used to install Ubuntu. Boot into this livesystem, and fire up testdisk, to see, if it finds your missing partition:

sudo apt-get install testdisk
sudo testdisk

The next steps are depending on your exact setup, and what is left of your partition. You can find more information on the testdisk homepage, and possibly in this thread

Thanks. I'm just trying testdisk. It looks promising. –  bin Jul 24 '12 at 20:01
