I got a strange problem.
I installed winxp and ubuntu 11.10 updated it and then I was mingling around with disk utility.
Don't know where I went wrong but I was unable to boot, seems like I deleted partition where GRUB was written.
With some efforts I could boot into WinXP, but when I put Live CD and open Gparted it showed whole disk unallocated... which is ofcourse not the case...
Can someone please help, its urgent!!
