Boot Camp, right?



You didn't follow the instructions properly. The Windows partition must be Fat 32 or NTFS. You chose to format it as GPT.



So, start over with Boot Camp.How to change mac book OS X's partition style to GPT partition style?
Are you using Boot Camp? The partition the Boot Camp creates is formatted for Windows and works fine.



If you DID use Boot Camp and are still having problems, use Boot Camp again to remove the current partition and start over.



Oh PS: your Mac is an Intel Mac, right? You can't run Windows unless your processor is Intel.
