when I get to the partitioning disk part of the bootcamp process, the blue bar which shows the progress of the partitioning goes full and does not change.

Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition codes). The only values that need modifications are the Boot flags and step 10. Accept all other defaults that Gdisk offers. Please see thesample Q&A as an example. These steps can be repeated if you make a mistake before you get to Step 12, otherwise start from Step 1 for these steps. Step 6 has numbers which are typed with a space between the numbers. Please see the sample Q&A before you execute these steps.
Here is sample Q&A for this section. Please notice the Press Enter/Return.
Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): Y
Creating entry for GPT partition #2 (MBR partition #2)
Enter an MBR hex code (default AF): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #3 (MBR partition #3)
Enter an MBR hex code (default 07): Press Enter/Return
Set the bootable flag? (Y/N): Y
Post the output of
sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0
for validation.
Can you post the output of
diskutil list
before we make changes?
Reboot and hold Command+R. Do you see a Recovery Console?
Click on Utilities -> Terminal, and type csrutil and press Return. What is the output?
Can you run dxdiag and post the output?
System integrity protection status: enabled.
Successfully disabled system integrity protection. Please restart for the changes to take effect
system integrity protection status: disabled (apple internal)
Has any hardware been modified on the 2012 Mac?
Notice the 'Kind' being Local, so it was directly-attached disk. Do you have the TM disk? If yes, can you connect it directly to the Mac?
Please install GPT FDisk - https://sourceforge.net/projects/gptfdisk/ - and post back. I can provide steps to correct the GPT vs MBR error.
Do you get a different error, or it still hangs on partitioning?
Do you have GPT Fdisk installed?
System Integrity Protection status: disabled.
Now, connect your USB installer, reboot and hold Alt/Option, and select Windows (not EFI Boot) and follow prompts.
