Harddrive not recognized

Hello,
I tried to install mac on my PC in which windows 8.1 is already running.
Mac installation failed and when i tried to boot into windows 8.1 but it doesn't open. i tried to reinstall it but it says that it cannot recognize any hardrive.
I cannot blame on hard drive connectivity as i can see my disk when i opened disk utility during mac installation.
I have 1 terabyte hard drive. In disk utility i found disk 01 disk 02 and disk 03 under terabyte harddisk. I tried and failed installing mac on disk03.
I dont think i partitioned my harddisk but still it showed 3 disks.if i have installed 2 os in 1 hardrive. How can i access windows 8.1? I also tried to format disk03 where mac installtion happend but still windows dont turn on.. please help
