i'm a newbie to Linux and had install Ubuntu 12.10 dual booted with Windows8. But the ubuntu several times showed some wierd kind of errors (which I've never heard of, like it got hanged and freezed). So I decided to upgrade to 13.04.
What I did: I wanted to increase the space allocated for the disk on which ubuntu was installed, so I shrinked one disk (using Windows Partion Manager) and deleted the one in which Ubuntu(12.10) was installed.
So when I restarted it, it showed "Grub rescue" kind of error. I tried to install ubuntu (by live cd), it does not show any partition. It shows the whole hard disk as a single partition.
Moreover, when I tried to mount any of the partition (of total of 5), it says something like "cannot mount, the file system is not in fine state ... shutdown windows and try again".
When I tried to boot windows Xp (the only cd I have atm), it stuck at "Examining disk at bus 0 ..." something.
I searched and have installed Boot-Repair, whose log is http://paste.ubuntu.com/5857634/
Somebody Please guide me as I don't want all my data be erased. ps: I've about 4-5 hours to run it otherwise my brother won't let me live at peace. :/
(Sorry if the question has already been asked. I searched but couldn't find any topic with exactly the same question, and moreover I have to save the data on the disk; I can't take risks).
