Kernel Panic problem on Brand New iMac 5k. Help!!

I got a Brand New Retina iMac 27 inch with a Fusion Drive. Yesterday as I was working the machine restarted and went into a panic loop. it loads until half way the loading bar with the apple logo and it goes into a message that reads "Your computer restarted because of a problem" I tried all the methods in forums with different start options. It's good to point out that I have no access to a CD-DVD with OSX cause apple doesn't give one anymore, or restore options because neither Command-R or Command-Option-R takes me anywhere. I tried resetting the NVRAM, Apple Hardware diagnostics, I tried fsck -yf command on single user and I tried resetting the SMC. None of these worked.

The restarting loop gives me a message every time too hard to read because on 27 inch monitor the print is super small on the error message and also disappears really fast. Is there a way to pause the screen when it shows the error message?

Also important to notice that I have a windows 10 bootcamp partition on the same hard drive and I can still access that no problem. When I do everything runs smoothly. The real problem for me is that as I mentioned before it is a brand new Imac so I had just finished transferring all my work from years there and I was about to copy it to my brand new External device, I am panicking over loosing my files. I though I would get my wife's mac and start mine on Target Disk mode. I did that and connected my iMac to her's over Thunderbolt. Surprise!!! now her imac goes into the restart loop with the exact same panic error message. I disconnected my iMac from hers and everything loaded just fine on hers. I connected again with her computer already started and my boot camp partition came up but the OSX HD partition where I have all my work doesn't come up anywhere. How could I retrieve my info? Also I looked for the panic log and I am posting it here. Please help. The most important right now is to save my data as the machine is on warranty and I will take it in as soon as I get my data safe.

Hello and welcome.

One thing I see is that the build number of OS X El Capitan and the Model Identifier are incorrect for your iMac:

From your log above:
Model Identifier: 16,1
Mac OS version: 15A2301

-Model Identifier 16,1 is an iMac (21.5-inch, Late 2015)
-Mac OS version 15A2301 is OS X 10.11 (15A2301) which shipped with the above model.

You stated you have an iMac 5k in your post title, and your first line says Retina iMac 27 inch with a Fusion Drive.

We first need to correctly identify the iMac model you are using, so we can troubleshoot with the proper information. If you could enter your serial number at the following link and let us know what it states, it will help us identify the correct model:

Check Your Service and Support Coverage

We can then try to troubleshoot what may be causing the kernel panics. You could also try holding the Shift key down until you see the Apple logo to see if it will startup in Safe Mode.
