Q: Bootcamp Assistant... Trying to Install and STUCK

Please help!!!! I spent half of the day today trying to install windows via bootcamp on my mac and am completely stuck.  I have gotten no where.

I have a iMac 27 inch late 2013 with 3.2 GHz Intel Core i5, 8 GB memory, 10.10.2 Yosemite. I’ve got more than 600 GB free space.  I am trying to install windows 8.1 via the disks.

I followed the instruction manual for bootcamp located here: http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf although it seems like it’s a bit old because it talks about software update off the apple menu.  It is made for windows 8.  I also followed this: http://support.apple.com/en-us/HT201468.

I have searched many others that asked this question and have tried their suggestions but I am still stuck.

Here are the steps I took:

1. Made my own ISO from the 64 bit windows 8 disk.
2. Opened bootcamp, selected all 3 of the boxes – downloaded the updates, etc.
3. Partitioned the drive so that there is 199gb dedicated to Windows.

It then gets stuck on the partitioning disk screen.  It looks like it’s 100% done on the status bar as soon as I push install, but then nothing else happens.

I had previously gotten past this screen, booted to windows, and when I tried selecting the partition to install windows on, it gave me an error message: “Windows cannot be installed to this disk.  The selected disk is of the GPT partition style.” I tried clicking “format” but that didn’t help.  I read a post where a person recommended to partition the drive via Disk Utility instead. I tried that but then got a new error…. So I used the bootcamp assistant to put back to one single partition and remove everything I did.  I deleted the data on the USB drive and started over.   Here I am now – stuck on the bootcamp screen trying to partition the disk.

When I go to disk utility, it only shows one partition with my full 1 TB of storage.

1. Also, if you are kind enough to answer, please take me step by step because I am great at following instructions but don’t know how to do this off-hand.  J
