Last week i tried to make the move from windows 7 to windows 8. but made the mistake of installing the wrong version. i installed windows 8.1 32bit and wanted 64bit. so when i tried to clean install windows 8.1 pro 64bit onto my pc through the boot setup, i found out that my hard drive was MBR and not the required GPT. next i tried to convert my hard drive with some software witch would not work as it said i required a 64bit operating system.
Please help. am a gamer and 32bit is not cutting it.
