Ive installed windows 7 onto a separate hard drive, which is named in vista as Drive Z, so that theres no risk of me damaging my main vista files etc. While windows 7 appears to load OK after selecting it via a dual boot option, i cant see or access anything from the vista disk/partition, as for some reason Windows7 referes to ( vista) Drive Z as Drive C, and Drive C ( the main drive with all the files and folders as well as the main vista OS) doesnt appear to exist to Windows 7. When i go top the computer management/storage/disk management i can see the main drive ( that vista calls drive C) but with windows 7 the drive has no drive letter. when i try and rename Windows7 Drive C ( the one vista calls drivez) to drive Z like in vista, i get an error message saying it cant be done. Is it possible to rename the drive that windows7 sits on, so that the drive with all the files folders etc etc ( as well as vista ) can be seen used and accessed?
