On your drive, is windows first or linux? From my experience, windows does not like to have anything installed before it. If installed after linux it tends to try to overwrite files.. Seems strange as one is fat32 and the other ext2, but it has happened to me before also. As long as I install windows first, then linux, then another linux in a totally seperate set of partitions, I dont have any problem. The lilo bootloader recognizes all 3 and you have a triple boot system. I wouldnt recommend trying to share the redhat swap file with mandrake. I would install mandrake as a totally seperate entity. The easiest way to remove redhat and start over is to start the install over again and when you get to the point where you can format the disc, delete the partitions containing linux. Then eject the cdrom before it goes any further. If you have partition magic it is a lot easier, but it can be done. You may have to use fdisc to get rid of the windows partition, im not sure. If you have partition magic you could just move the partition with windows to the front and reinstall over it. Then you would have an unused partition that you can install linux in. Maybe a roundabout way of doing things but it works for me. Hope that helps
