I have a windows 7 Pro machines that wont boot up. I have tried last know good..., safe mode and system repair but no luck. I need to somehow get the data off the hard drive. I took the hard drive out and put in another computer, the dish management sees the hard drive but My computer does not does not recognize it for me to copy data off HD. Within disk managemnt, it does not have an option to assign drive letter. My only option is to Delete when I right click on the HD. How can I mount the drive so I can copy data off it?
