[ubuntu] My computer will no longer boot

view story

http://ubuntuforums.org – I have a dual boot (Windows 7/Ubuntu) system and I recently accidentally formatted a 500GB partition on a 1TB hard disc (see thread "Lost Data after formatting hard disc"). I could not recover the original partition but recovered the important files I had lost. Then I tried to format the partition back to how it was originally (500GB NTFS). After my disastrous accidental formatting the 500 GB had broken into about 5 sections - 3 large ones of circa 410 GB, 50 GB and 9 GB and two small ones (MBs). I used GParted but I could not see a way to put the Humpty Dumpty 500 GB back together. (Hardware)
