So I had windows 8 on my MacBookPro 2012 mid and accidentally erased so now I'am trying to install it again. I have my USB and then when I go to the boot up mode there is Windows and EFI which one do I install windows on? I think I do EFI because when I try windows and I can't do it because it says the GPT is wrong or something but when I use EFI I format the BOOTCAMP partition and then it goes to the install process. It's going good until I get this error. "Windows detected that the EFU system partitions was formatted as NTFS. Format the EFI system as FAT32, and restart the installation." So I go back to OS X and go to Disk utility and change it to FAT (dos) I believe it is called. Then I go to EFI and try to install windows 8. When I get their it says it cant install on the partition because it is formatted as FAT and needs to be NTFS. So on the EFI I go to advance drivers options and click format and then it formats I'm guessing to NTFS and then I press continue. Then everything goes good until I get the error I get before "Windows detected that the EFU system partitions was formatted as NTFS. Format the EFI system as FAT32, and restart the installation." Im not sure what to do anymore and this is really hard to understand if anyone knows what to do that would be great. Thanks in advance.
