Q: Windows 8.1 install GPT partition error

Hello,

 

I have been trying to install windows in my mac, I used to use boot camp before but know it keeps crashing with the partition type. I tried to change the partition toGTP but it keep saying windows can't be installed on there. Recently I check a post where user Loner T help a guy with the same problem. Here are my specifications.

 

/dev/disk0

   0:      GUID_partition_scheme                        *2.0 TB     disk0

   1:                        EFI EFI                     209.7 MB   disk0s1

   2:                  Apple_HFS Macintosh HD            1.8 TB     disk0s2

   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

   4:       Microsoft Basic Data                         249.0 GB   disk0s4

/dev/disk1
