[jumpin_hunk]

I have first used try ubuntu option form dvd 14.10. and I do not want to erase entire disk. but the disk has previous fedora installation which I was not able to delete. accidentally Itried LVM (I choose accidentally) and clicked continue, I went back again and choose the last option something else (customize), but I am not able to see NTFS partitions. All i See now lvm_1 something, I am worried that I lost windows7 installation, my docs, and desktop etc which I did not back up. Can you please help me will I be able to retrieve since I have not installed ubuntu but i just stopped at the partitioning time. Please help me
