I loaded ubuntu inside windows using wubi. If I select ubuntu from that boot menu everything works fine. I can not boot to windows now. I have worked for two days to determine the problem and have been unsuccessful. I recently tried to do a repair instalation and can not even do that. When I select the repair install and get to the set up screen I notice that the c: drive says unknown disk "partition1 unknown" 76340 mb (76340 mb free). I know this is not an empty drive because I used ubuntu to get all the files that I did not want to loose off that drive. When I select that drive to set up windows xp on. I get the following message. This partition is either too full , damaged, not formatted, or formatted with a incompatible file system. To continue installing Windows, setup must format this partition. Before I do that is there anything I can do to same the files.
