Recover formated partition files

[Code.Illusionist]

I opened diskpart and did next:

>list disc
>select disk 0 (partition D with files)
>list partition
>select partition 4 (100GB free partition - nothing on it)
>CLEAN
>convert gtp

DONE. After i tried to install new os and on my surprise , there was only one partition (with no files on it).

And now, when i  have no OS, is there a app that I can use on USB to recover formated data?

I'm sure Hiren's boot CD have something in their arsenal, but grab either an old version or a "recovered" version (which is new version but with added proprietary tools which are removed in new versions).

Active@Boot Disk is a bootable recovery disk

I've used it in the past. I'll see if I can find a cracked version for you

k got it and made a post for it:

Try to recover losted partition structure and that might be enough. Because afaik "clean" command only overwrites partition information.

Here is few links to tool/tutorial that might help:

^That program might be on hirens boot CD which kulverstukas mentioned.

Consider before doing any recovery attempts to live boot Linux and do some dd magick to make image from that drive. Just in case if something goes more wrong. You're most likely familiar with this, but if not check proxx's tut: https://evilzone.org/tutorials/(tutorial)-linux-imagingdd/

Thanks guys. I solved the problem with booting Lubuntu on live USB with rufus, and then using testdisk on linux. That's all fine now, I recovered all data. The problem I have now is when the proccess of instalation is done for the first time, after restart, he ask me to start windows normally , and so I pick that, but it seems he fall into some kind of endless loop. And he repeat that step over and over with no effect whatever I pick.

Possibly just a bum install then? I'd try one more fresh install. Maybe use a new install disc/medium as well just to rule that out too.

What do you mean by bum install?

Use Windows Install Disk and choose Startup Repair or equivalent.

I usually run into this issue when cloning partitions to disk instead of disk to disk cloning.

You may have to reinstall grub2 or whatever after windows is done repairing - if your dual booting win/nix.

I downloaded another copy of Win7 , set it on USB bootable and installed. All worked fine. Yey.

I just meant corrupted. Glad you fixed the issue though.
