So I had a problem installing my OS so I decided to use diskpart and I mistakenly typed clean in my troubleshoot command and my volumes and partitions disappeared. It wasn't clean all, I know my data is still there (450+ GB), i didn't install an OS yet nor did I set a partition, also I tried parition wizard bootable 64bit and I placed it into my USB flash but it wouldn't launch, I have my USB flash as the first priority at launching my PC... Please help, thanks in advance...
