I have a serious problem: I installed Ubuntu 14.04 on my computer by selecting the Replace Windows 7 option. During installation it deleted all my windows partitions: D:
, E:
and F:
.
How can I recover my deleted partition data?
I read a post regarding recovering data using testdisk. But it recommends having an external hard drive with double the capacity of the existing hard drive. At present, I do not have such a hard drive. Is there any other way?
