Can't boot from bootcamp after adding partition using disk utility

My question is similar with Repairing Boot Camp after creating new partition,


i recently install the el capitan + windows 7 (using bootcamp), all working fine after i adding the third partition. (i plan the third partition will be use for dropbox, so mac and windows can sync-ing one dropbox folder for both of them).


after i make the third partition, and restart the system, i hold OPTION and not found the windows.


my mbp spec:


MD101 2012 13",

SAMSUNG SSD PRO 850 256GB,

RAM 16GB,

osx elcapitan + windows 7 ultimate.


thanks

MacBook Pro, OS X El Capitan (10.11.3), RAM upgraded to 16GB

You created an extra partition, and to make Windows work, we 'combined' the OSX and EFI partitions into a single 'part' for Windows to 'see' (using 3 4 5). Under normal circumstances it is 2 3 4, which allows a 1:1 mapping, and you can see OSX partition, if it is JHFS+. In your current configuration, it is not possible for Bootcamp drivers to see this 'combined' partition.
