Trying to install Mavericks on SSD with Windows already on

[indranil]

Hi,

Hardware config:

MSI MPower Z87 Motherboard
Intel i5 4670k 3.4GHz (with Corsair H100i liquid cooling)
16 GB DDR3 RAM @ 1333Mhz (I have an XMP option of running it at 1867Mhz, but haven't turned it on)
Zotac NVidia GTX780 3GB Graphics card
Samsung 840 Pro Series 256GB SSD
WD 2TB Black HDD

Problem:

I set up 2 partitions on my SSD, seeing as it was already GPT, and not MBR.
I pmpatch-ed my bios(uefi?) and flashed it, and now the Mac installer loads.

But I can't format my extra partition in Disk Utility, as it comes up with "Mediakit reports not enough space on device".

Any help on this problem would be appreciated. I can try and do a gpt destroy and create(http://blog.kyodium.net/2010/11/increase-disk-and-partition-size-in.html), but I am afraid it'll erase all my data.

Have you tried erasing the disk (of the partition that you want to install it on) first?

I'm sure that'll work, but I'm not sure if I will be able to get my windows partition back (backup -> restore) + I don't know a great way that that works. But I might have to do that in the end.

No, don't erase the drive with your Windows partition on it, just the partition where you want to install Mavericks. I did the same thing and am successfully dual booting Windows 8 and Mavericks.

Yes as said above erase the partition you want to install OS X on not the hole disk. I have not tried to install OS X to a disk that has Windows on it as I like my OS's on separate SSD's but that should work.
