hi all need your help, i'm abit stuck i installed windows in hda1 then fedora core 6 on another partition (hda2), and red hat 9 on hda5 [according to grub's hard disk notation]. i also created 2 swap spaces for both linux versions. Also, i did not create boot partitions on both linux os's. I can boot into windows and red hat, but when i try into boot into fedora i get this error (this might be important: i'm using grub for red hat) rootnoverfy (hd0,1) chainloader +1 "Error 13: Invalid or unsupported executable format" Press any key to continue... And here is my partitioning table: Disk /dev/hda: Device Boot Start End Blocks Id System /dev/hda1 1 4199 31744408+ 7 HPFS/NTFS /dev/hda2 * 4200 7423 24370605 83 Linux /dev/hda3 7423 7562 1052257+ 82 Linux swap /dev/hda4 7563 10587 22869000 f Win95 Ext'd (LBA) /dev/hda5 7702 10587 21818160 83 Linux /dev/hda6 7563 7701 1050777 82 Linux swap Partition table entries are not in disk order and here is my grub.conf file # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You do not have a /boot partition.
