I had Windows 8 installed on a partition. Installed Ubuntu 12.10 on another, it works fine, but when I try to boot Windows 8, it says

error: device format "ldm/84ec4a8-84ad-11e1-a109-002655b2e743/Volume1" invalid: must be (f|h), with 0 <= N < 128.
Press any key to continue...

And then on the next screen

A disk error occured
Press Ctrl+Alt+Del to restart

Well I have the same problem. It's not that easy to make Windows 8 dual-bootable with another OS. This should help you (Answer 1). But you have to re-install Windows to do that, and that's where the next problem came up for me: Trying to install Win8 from DVD, the installer doesn't recognize partitions any more... I think formatting the Windows Partition (C, in most cases) could be a solution, but I don't know how to do that in Ubuntu.

Is the LDM from dynamic partitions? Dynamic also on gpt as LDM

GRUB2 2.00 recognizes defunct LDM headers from old dynamic partitions
