To test CentOS 5, I loaded from DVD adding it to a system at home running Fedora Core 7 T2. Partition Layout is: /dev/hda1 - / for the RH7T2 system /dev/hda2 - /home /dev/hda3 - swap /dev/hda4 - extended /dev/hda5 - / for CentOS 5 The system loaded cleanly and gave me the opportunity to tell grub about the other system. CentOS boots fine. Grub Stage 2 will show me both systems. However, If I choose the FC7T2 system I get the following output: --------------------------------------------------------- Booting 'FC7T2' rootnoverify(hd0,0) chainloader +1 Error 13: Invalid or unsupported executable format --------------------------------------------------------- The CentOS grub.conf on /dev/hda5 looks like: #: cat /boot/grub/grub.conf # 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. This means that # all kernel and initrd paths are relative to /, eg. # root (hd0,4) # kernel /boot/vmlinuz-version ro root=/dev/hda5 # initrd /boot/initrd-version.img #boot=/dev/hda default=0 timeout=10 splashimage=(hd0,4)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-1.2747.el5) root (hd0,4) kernel /boot/vmlinuz-2.6.18-1.2747.el5 ro root=LABEL=/1 quiet crashkernel=64M@16M initrd /boot/initrd-2.6.18-1.2747.el5.img title FC7T2 rootnoverify (hd0,0) chainloader +1 --------------------------------------------------------- Any clues on how to fix this? Note, I am posting to both groups since I follow both and cannot figure out which is the better choice. -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
