Q: Help! Bootcamp issue after partition

Can anyone help me out. I have my bootcamp working normally, than in order to get more space, i have used the disk utility to partition my mac HD one more time. Than i rebooted it to the bootcamp and used Mini Tool Partition Wizard Home Edition to expand the bootcamp HD. It worked perfectly but when i went back to the Mac HD to partition one more time ( i calculated wrong the amount of space i need back there) i noticed that i the bootcamp space in the disk utility did not increased, in fact it changed its name to DISK0S4 and i cant start my mac as a windows. Can anyone help me out.

PS: Sorry for my english, i'm Brazilian.

iMac (21.5-inch Mid 2011), OS X Mavericks (10.9.5)

    Your English is fine.

     

    This is very encouraging. Please re-create the Hybrid MBR first, otherwise Startup Disk -> Bootcamp will not work.

    I seems that i can open my bootcamp and reboot in it. Does that means it is over or i need to do something else?

    Test to make sure you can switch to Bootcamp from OS X.

    Test to make sure you can switch from OS X to Bootcamp.

    Test to make sure you can see all your files.

     

    Make a backup of OS X and Windows.

    It works!!, Thank you very much for your patience. You really helped me a lot. Never doing it again though, too risk, better buy an external HD . By the way, do you know if an imac can bootcamp through an external HD? or can i install an second HD to my imac? And again, thank you for your support.

    Excellent.

     

    You can add a second disk to an iMac, but Windows will not install on an external disk. Bootcamp on a Mac with more than one internal disk requires special procedure. The other option is to use WinClone.
