Well, I'm trying to install a x64 bit of windows 7 pro and I kept getting the error failed to partition the hardrive, I give it exactly 100gb of storage. Im not sure what version of yosemite I'm running because im not with my Mac right now.
MacBook Pro (13-inch Late 2011), OS X Yosemite (10.10)
When you get to your Mac next, try the following in order, ...
1. Run Disk Utility Repair and try BC Assistant - Using Disk Utility to verify or repair disks - Apple Support.
2. If that does not work,
Resetting the System Management Controller (SMC) on your Mac - Apple Support
How to Reset NVRAM on your Mac - Apple Support
and try BCA again.
3. If that does not work, then
a. Back up OSX using Time Machine - Mac Basics: Time Machine backs up your Mac - Apple Support.
b. Boot into Internet Recovery - OS X: About OS X Recovery - Apple Support.
c. Erase your internal drive and restore from the TM backup in Step 1 - OS X Yosemite: Recover your entire system.
Try BCA again. Please be aware that TM does not backup Bootcamp partitions.
