I install ubuntu 13.04 on my PC which has windows 8 alreday installed. During install, I checked the second option (about LVM partitions). After install, I cannot boot neither on ubuntu nor in windows. I have this error message : "No boot disk has been detected or the disk has failed" Furthermore, I don't see my NTFS partitions. I tried to repair the boot loader with Boot-Repair but with no success. I'm really lost. Could you help me. Here is the install report :


Thank you in advance.
