I was going to reinstall ubuntu on a pc. It already had ubuntu on it, but It was an old version and instead of updating it several version I wanted to just start fresh. So I went into windows and used A partition manager of some kind ( i dont remeber what it was called) to delete the partitions that had ubuntu on it. I guess that was a mistake, because now when I boot it the computer goes into grub rescue, and I dont know what to do. I booted it from the live cd and mounted the harddrive, and the windows data is still there. When I run gpart, it doesnt detect any partitions. Just /dev/sda/. I do not want to erase the whole disk, because i need the windows data and I do not have the windows install disk.
So anyway to fix the partitions?
