Hi everybody,
i'm facing a big problem ever
i took a stupid step in my life
i was using windows 8 after few months i realized it's too slow
i've a encrypted partition created on windows 7
when i try to format C: to re install windows 7 i deleted the encrypted partition
it contain very important life memories .. scince 2001 .. images, videos and contacts
i need to restore those data ..
any help please?

Did you do any more that format it?
Did you start to install Windows 7 on it ?

If you didn't do any more than format (quick format by default)
then most of the partition contents are still there

However since they were encrypted it causes another problem
Was it encrypted with BitLocker ?

Do you have the recovery key (48 digits)

It should be possible to access the damaged partition (as even though some info id overwritten there are several copies of the BitLocker metadata) and use the key to get to the data

But you will need an expert to assist you

thnx xsoliman
i didn't any thing more than formatting ..
i didn't copy any data after the creation
the partition in the end of disk
i have 3 key files .. i think the last one is the right key ..
aslo i know my password
can you help me ?

I might have spoken too quickly
If the format recognised the existing partition was BitLockered it may have cleared all copies of the BiLocker metadata on the partition [not good]
If the setup deleted all partitions before creating a new one and formatting you might be ok

You need to use a local data recovery specialist
Shouldn't be too much work or too expensive to determine if it is recoverable

thank you .. i'll try to find a good person to recover my data ...
