Updating bug description - I'm having the same problem in a VirtualBox environment (disks partitioned as GPT, no EFI).
I was able to use ubuntu-11.10-server-amd64 to install a system with mdadm RAID1 (GPT partitioning, 1MB "BIOS GRUB" partition, ~20GB RAID) and have the system boot successfully, but trying to install ubuntu-11.10-desktop-amd64 with the same partitoning failed. chrooting in and running grub-install again gave 'grub-probe: error: no such disk' as above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/880766 Title: ubiquity and grub-install: fails to install grub on software RAID To manage notifications about this bug go to: https://bugs.launchpad.net/grub/+bug/880766/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
