I wanted to fresh instal windows 8. Bootable DVD decteced but when I click fresh instal I cant see any HDD in my laptop to instal the OS in that particular HDD. I have only 1 HDD SSD Hybrid one. This same problem is there while I try to instal Ubuntu. But HDD is fine and able to see the contents in the HDD if i try to see through Ubuntu ( Note Ubuntu not installed but mounted) .
