but the third screen says:
C: Partition1 [Unknown] 76309 MB < 76308 MB free >
Unpartitioned space 8 MB
I have the options: ENTER = Install D=Delete F3=Quit
I read in the guide that if I use Install I loose all the data in that partition, so I tried Delete. That tells me that the partition I tried to delete is a system partition and that it may contain diagnostic or hardware donfiguration programs, programs to start operating systems (such as Windows XP), or other manufacturer suppllied programs.
I would not be thrilled about loosing everything in that Partition1, I can live without the Unpartitioned space stuff, one way or another (though I have no idea what is in there or why)...
