How can I find C:\ and retrieve Windows files from Parallels on a Mac?

Friday, 15 days before, the last program I have put in Windows 7 using Parellels 5 on a Mac (Snow Leopard) desktop computer, was the Serial Retrieval Utility.

I don’t know what happened, but when next Monday I tried to get into Windows, I couldn’t do it. It gives the “setup is starting…” on the Windows 7 wallpaper, and in the taskbar says that Parallels tools are not installed.

When I try to install the Parallel Tools I have to put some GB on the HDD, which is 64 GB, but I’m afraid that perhaps I lose some data, even if I don’t know for the time being, where is located this data.

Can somebody tell me where is my C:\ disk? And how I can find all my Windows partition, to copy what I don’t like to lose? Please!

I tried to put a new VM, with a new version of Windows 7 and as key I wrote xxxxx.xxxx…., and on the Windows desktop opens a window where is: “The unattend answer file contains an invalid product key. Either remove the invalid key or provide a valid product key in the unattend answer file to proceed with Windows installation.”

I don’t know where these files are to change them. Also the old VM, does not open, and gives the same “unattend answer” error.

Please Help.
Thank You.

      the above question and the solutions posted in response are over a year old. The software may indeed not be up to date anymore. Did you find any more relevant tools?

    If you want to find your partitons then try Partition Find and Mount

    why you dont uninstal VM with revouninstaller?

    Also clarify better your problems. Exactly what you want to do? From where you got this Serial Retrieval Utility software?.

      Dear ha14, thanks for answering.

      Checking on the, i saw that it is a windows program.
      I respect the revouninstaller, but it's the same.
      The story is that, into the mac, i put the Paralles VM, and into this the windows 7 partition.
      I can't get into windows 7, to change anything, as I stated before and i'm afraid to uninstall the VM, because of loosing everything inside.
      The c: dir is somewhere in the mac, but i don't know where to search.
      I don't remember from where i took the Serial Retrieval Utility, but i don't believe that this makes the problem.
      Any idea?
      Thanks again
