I have just installed Ubuntu 12.10 on my PC and the installation completed well. But now the problem is I am unable to boot Windows 8, in GRUB menu it shows both options, If I choose Ubuntu, it boots smoothly and if I choose Windows 8 it shows the following message:

error: device format "ldm/958e9087-d9d5-11e2-be71-0024d7280798/Volume1" invalid : must be (f|h) dN, with 0<= N < 128  

press any key to continue...

and after some seconds... it shows :

A disk read error Press Ctrl+Alt+Del to restart.

  1. Disable SecureBoot in your BIOS ( see this paragraph )
  2. Run Boot-Repair's Recommended Repair
  3. Reboot, you should be able to access both Ubuntu and Windows.
