I've upgraded my OS X to the latest Yosemite GM Candidate and cannot for the life of me figure out how to partition my SSD for BootCamp. Here are some screenshots of the problem:
And when i try to partition from Disk Utility:
What is the problem and can it be solved? I read somewhere something about needing to wipe my hard drive and start over with a fresh OS X install, but i really would prefer not to do that, any help is appreciated. Thanks.
P.S:
I've tried verifying disk permissions, and repairing in recovery mode. Nothing worked.

This Mac Book Retina was originally delivered with Mountain Lion. The upgrade history contains Mavericks, several Yosemite DPs and finally the Yosemite GM Candidate.
One of the Yosemite Developer Previews transformed the previous
Apple_HFS partition
into aLogical Volume Group
.The (only) Logical Volume is not revertible:
The Boot Camp assistant can't modify the partition map and shrink such a LVG to free up some unallocated space for a Windows installation on a hard disk.
The only possibility (we found) to solve the problem is a complete reinstall:
Internet Recovery Mode
by pressing altcmdR(alternatively you may use a Mavericks or Mountain Lion Install Thumb Drive)
Terminal
from the menubar/utilities312C0A5B-AC3E-4008-895F-6EDFDD386825.
Run the following command:
According to the number found above it would be:
This will delete your CoreStorage volume and your Recovery HD and reformat it as a simple HFS+ volume.
Terminal
Disk Utility
and format/partition/rename the internal drive. Choose1 Partition
,Mac OS Extended (Journaled)
and GUID partition table (available with theoption
button). QuitDisk Utility
.Boot Camp Assistant
, repartiton your Mac and install WindowsAt step 10 one may boot alternatively to a Mavericks or Mountain Lion Install Thumb Drive if available and install the respective OS X.
Starting into
Recovery Mode
at step 3 doesn't help because it's impossible to delete the LGV then.
