Using Cygwin the output is not mest up but during the installation I'm stuck at: "No disk drive was detected. If you know the name of the driver needed by your disk drive, you can select it from the list. Driver needed for your disk drive: 1: continue with no disk drive [*], 46: loop," Should I select the default option (1) or what should I do? Thanks for any help. -- John Doe
