Problem about install windows 10 in mac os with bootcamp.
problem 1: stuck at "partition disk".
solution:
- force quit boot camp 
- then open disk utility. 
- click partition, delete all other partition (using the - symbol)that bootcamp made. including: OSXRECOVER and BOOTCAMP. 
- open bootcamp again and try re-install again. 
problem 2: An error occurred while copying the Windows installation files
reason: because bootcamp using a 8g FAT32 disk partition to copy windows file, since FAT32 can not support file larger than 4g. any windows file larger than 4g will cause this problem happen.
solution:
- use a ISO that have file size smaller than 4g.
- known iso that can not use: 1703 1803 1809 (may work on your computer)
- known iso that can use: none
