I have an **bootable external disk** which a **Linux** is installed on it. I can boot into it and use Linux there. It is a 1TB disk. I think it will be better if I can **also** use it as a storage when I use my **Windows 7 machine**.I plug it in the windows 7 machine. But it cannot show up. Windows 7 says the drive is installed successfully but it is not listed.

Is there a way to make it recongizable by windows 7 and also keep the bootable Linux installation?

I installed the Linux 2 years ago by using a live CD when I bought the external drive. I guess it was formatted as Linux file system? I am not sure though.

**EDIT:**

My case is not a dual boot disk. Mine is a separated external movable bootable USB disk.

I have attached a screen shot about my situation. The one selected is the 1TB external drive. I have another bootable USB drive plugged in and it is listed by the Windows 7.

If I use 3rdparty software, it will allow me to read and write as usual?
