I have installed Ubuntu 12.04 on Sony VAIO with preloaded Windows8. I allocated a space of 16gb seperately without creating a new volume and then put the Ubuntu installation disc.I had to Boot in UEFI for using Windows,and Legacy Boot mode for using Ubuntu. Everything was fine until a few days, then the issue starts : Both the OS became too slow and the partition editor shows that Ubuntu was loaded in the partition of windows itself.. Now i formatted that allocated space of Ubuntu partition from Windows itself (normal NTFS format) inorder to reinstall Ubuntu. Even though after the format,i get a prompt to chose The OS at Boot time. I dont exactly understand the problem… Please help me out.
