Hi, I've got a machine with three hard-drives in it. two sata and one ide. I've a fedora 10 (upgraded from 9) on the first sata drive, and I've installed fedora 11 on the second sata drive. The machine boots off the first of these drives and the ide one contains windows. I copied the lines out of grub.conf on the f11 disk, and copied them to the grub.conf of the first disk, and reinstalled. However, f10 boots fine, f11 doesn't boot. and grub gives me an error 17. The lines from the f11 grub.conf are default=0 timeout=5 splashimage=(hd1,0)/grub/splash.xpm.gz hiddenmenu title Fedora (2.6.29.4-167.fc11.x86_64) root (hd1,0) kernel /vmlinuz-2.6.29.4-167.fc11.x86_64 ro root=UUID=7ba6f364-68c2-4dad-a54e-18c3464b0eb5 rhgb quiet initrd /initrd-2.6.29.4-167.fc11.x86_64.img title Other rootnoverify (hd2,0) chainloader +1 title Fedora 10 rootnoverify (hd0,0) chainloader +1 and I've copied the f11 section into the f10 grub.conf, title Fedora 11 64-bit root (hd1,0) kernel /vmlinuz-2.6.29.4-167.fc11.x86_64 ro root=UUID=7ba6f364-68c2-4dad-a54e-18c3464b0eb5 rhgb quiet initrd /initrd-2.6.29.4-167.fc11.x86_64.img Not sure if it's to do with how root is written, whether I'm using an older version of grub (GNU GRUB 0.97) or what. The full f10 grub.conf is below. Everything is ext3 except \ on the f11.
