I will describe the problem but first a question. We know that the first sector on the first disk is the MBR is found a boot loader and the partition table. One assumes that that the OS starts in cylinder 1. What is stored in the rest of the cylinder 0 other than the MBR? Now the problem. We install Linux and W2k on a Dell machine. The Linux runs. Now we boot the W2k. W2k has a disk manager program which allows you to see what W2k thinks about the structure of the disk, When the program is run it tells us that the Linux partition is Fat 32. We reboot the machine and find that the Linux is ruined. In will not boot and the disk seems to be written over by W2K. Now we have done this about several 100 times over the years and this has not happened before. Nor does it happen on other machines. Can someone suggest where to look for an answer? Can anyone confirm an impression that w2k keep a separate partition table that it uses, and if so where is it located? -- ------------------------------------------- Aaron Konstam Computer Science Trinity University 715 Stadium Dr. San Antonio, TX 78212-7200 telephone: (210)-999-7484 email:akonstam@trinity.edu -- Psyche-list mailing list Psyche-list@redhat.com https://listman.redhat.com/mailman/listinfo/psyche-list
