This question already has an answer here:
I had Win 7 in
C:\ and other data in
F:\ G:\ H:\ partitions. Installed Ubuntu 12.10 with option
Erase win7 and install Ubuntu and checked LVM option. After installing Ubuntu I'm not able to see
F:\ G:\ H:\ partitions.
Does this mean I lost all data on
F:\ G:\ H:\ or is there any way to recover?
