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
