I recently upgraded my computer to Mavericks (I believe I have the latest version, 10.9) and I've been trying for 2 days now to install Windows via Boot Camp on my computer, but it always fails at the Partitioning step.
I have tried multiple different things, such as…
- Partitioning via Disk Utility
- Going into the Recovery HD and trying to repair the HD
/fsck/sbin -fyin Single-User mode- I have used a Mountain Lion USB install to use the Disk Utility there
…but I keep ending up with the same errors:
- Partition map is broken
- Verification of the file system failed
When I try to repair it using Recovery HD I keep getting "Live file system repair is not supported" and there is basically no way for me to partition, unless I want to downgrade to another version of OS X which I don't feel like doing. Any ideas?

This indicates that the partition map on the drive is corrupt and needs to be repaired.
Backup all your data (possibly with a disk image of your startup disk partition) and boot into a separate disk (not Recovery HD).
Select your drive in Disk Utility, and choose the Partition tab.
Change Partition Layout to 1 Partition or 2 Partitions. This will erase the entire disk, replacing the corrupt partition map with a new one.
Click Apply.
