[Bug 836378] Re: Oneiric upgrade, boot hangs at error: symbol not found: grub_divmod64_full

[Dave Jones]

I'm similarly affected, on a fresh install of 11.10 using the alternate
cd (which has been successfully used to install on another machine) at
boot up I get the same error message.

The machine has various drives:-

1) Sata 80Gb, partitioned as 25Gb ext4 /home, 4Gb swap, balance as ext4 /home
2) Sata 300Gb partitioned as 100gb ext4 Data and 200Gb ext4 Data
3) Pata 320Gb partitioned wholly as ext3 Data

Both Sata drives were formatted on install.

Machine itself is a Dell Optiplex 210L

Talking on irc, it was suggested that a copy of /boot could help with
solving the bug.
