My experience doesn't quite match other posters reporting similar bugs. In my existing Red Hat 6.0 system, I don't have any NTFS or HPFS partitions, and the root is on the first drive, but the installer still fails. It says (quoting from memory, sorry) "I can't do an upgrade because you have no existing Linux partitions". I don't find any other error messages, and it does not retry looking for existing partitions. If I press Ctrl+Alt+F2, create a device node for /dev/hda, and look at it with fdisk, fdisk sees all the partitions correctly. Here is my fstab: /dev/hda5 / ext2 defaults 1 1 /dev/hda1 /c vfat gid=30060,umask=002 0 0 /dev/hda7 /d vfat gid=30060,umask=002 0 0 /dev/hdb5 /e vfat gid=30060,umask=002 0 0 /dev/hda6 swap swap defaults 0 0 /dev/fd0 /mnt/floppy auto noauto,user 0 0 /dev/fd1 /mnt/fiveinch auto noauto,user 0 0 /dev/cdrom /mnt/cdrom iso9660 noauto,ro,user 0 0 /dev/cdrom2 /mnt/cdrom2 iso9660 noauto,ro,user 0 0 none /proc proc defaults 0 0 none /dev/pts devpts mode=0622 0 0 ------- Additional Comments From 10/16/99 22:46 ------- The problem occurred because my /dev/hda5 is an extended partition inside a primary partition of type 0xf, as discussed in the comments on bug 5555. I was able to do an upgrade by temporarily changing the primary partition type.
We are releasing an errata fix for this problem the week of October 18th. Am discarding bug as details are covered in #5555, please see that bug for further details.
