I faced a similar problem, on ONE of two identical machines (4x2TB Hardware Raid 6 (using dedicated interface) with 4 AMD 6174 CPUs - 48 cores). Got it working by following the instructions in "Grub2 recovery" in here: http://www.dedoimedo.com/computers/grub-2.html#mozTocId842078 Had to modify some mounting steps, as I was letting ubuntu mount the HD in the /media/ folder using its UUID.
It looks like the critical step is the reconfiguration of grub-pc, as on one trial with just reinstalling grub2 did not work. I wonder how it will behave in a future grub or kernel update. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/657788 Title: grub minimal bash after first Maverick update -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
