When I booted from the alt CD and selected "boot from first hard disk" I ended up at the "grub rescue" prompt. So I rebooted again from the alt CD and selected "rescue a broken system". Ran grub-install and rebooted. Still will not boot from /dev/sda. But now it will boot /dev/sda if I first boot from the alt CD and select "boot from first hard disk".
I ran the http://sourceforge.net/projects/bootinfoscript/ Attached are the results. ** Attachment added: "Results from bootinfoscript.sh" https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/883720/+attachment/2581785/+files/RESULTS1.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/883720 Title: oneiric fresh install to raid1 from alt amd64 CD - "grub-install /dev/sda failed" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/883720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
