Well this is quite strange, but it doesn't seem to be anything that you can't handle slowlane. When you posted the output of the expert options for partitioning, it showed that it was trying to shrink a windows partition on /dev/sdb. sdb means the second drive found on the SCSI/SATA interface on your mobo, which im guessing is your D: drive. So maybe your windows is installed on your D: drive, or maybe SUSE is trying to put itself there. If you want to put SUSE on C:, you'll have to run fdisk as a few people mentioned earlier. Try hitting ctrl+alt+F2 instead of F1, this should take you to a command prompt instead of seeing the code or blank screen of the X server on tty1. If that works, login as root and run the fdisk -l command. If not you might be stuck having to configure your partitions through the SUSE installer, which will be more difficult. And in response to your frustration earlier, people here only ask questions to help answer your original question thoroughly. Please try not to get angry with people who are helping you, or else we won't be quite so inclined to do it anymore :-).
Please let us know how everything goes.
