Partitions sizes not reported correctly after removing Bootcamp

Hi,

I am reading through all these threads and am hoping that @Loner T can help (or anyone, but he seems to have a good understanding of this). I did the dumb thing and uninstalled bootcamp using disk utility and now have the dreaded split HD in two partitions. I want to reinstall bootcamp but when I try to make a third partition for a Bootcamp HD it takes up all the free space on my HD. Not to mention that the reported space available in Disk Utility, doesn't match the "Get Info" amount on the Macintosh HD. I am including screen shots and will send the cs list and list in hopes you can help me. I have a time machine backup so I don't mind formatting (again), and I have a WinClone image of the old Win7 (but it was crashing hence the removal in the first place). Thanks for any help!

iMac (27-inch, Late 2013), OS X Yosemite (10.10.3)

OK, this will be a while, I will need to restore a TM after formatting and create the BOOTCAMP partition first. Thanks for hanging in there with me through this...😊

If you insert your BCA-created USB (which has the ISO and BC drivers) and boot from it, you should be able to select the Bootcamp partition in the Installer, let the installer format it as NTFS and install Windows.

After hours of more reading, it seems that the USB3 might very well be the issue. I've seen some people have success but they all seem to be using BA so maybe we need to go back the the Core System approach?

Since your iMac is a late 2013

I don't have a macbook. It's an imac 27" late 2013.

You can also install EFI Windows provided we partition it correctly, without the use of a Hybrid MBR.

The issue is not a USB3 port, but a USB3 flash device. You need to use a USB2 flash device. On my Mac, I have both USB3 and USB2 support and you can see the two different 'buses'.

Then I am perplexed because I am using an old Western Digital 1TB HD that is definitely not USB3 and every time I've tried to install Win7, I have no mouse or keyboard control.

You cannot use an external HDD, you need to use a USB2 flash device. Please do not use any USB hubs.

When you use an external USB connected device, the Windows installer (erroneously) assumes that the external HDD is a candidate for Windows installation and will refuse to build the PE (Preboot Environment). This also a problem with large flash drives, for example, the installer causes problems if you use a 64G/128G USB flash drive.

Can you find a USB2 flash drive which is 8-16GB?

I have a 16gb scandisk Cruzer which is USB2. I will do the BA drivers and ISO load onto it.

Do you also have a BT Mouse/Keyboard turned on and in the vicinity? If yes, turn them off. Can you check and verify that the USB is USB2? On the iMac there are 4 USB ports, can you try each one sequentially?
