Bootcamp not booting after install rEFInd for dual boot

This is my 1st post on this site, hope I don't screw up.

I tried to install rEFInd boot manager and screwed up my Bootcamp so windows 8 will not boot. It does show up on boot holding the option key, but it does nothing but a black screen when selected. Same when selecting to boot from CD/DVD, black screen. I've read a few posts similar to this but he suggestions from "LonerT" did not fix my issue. I'm hoping LonerT or someone of his knowledge base is available to help me, I really don't want to reinstall window if it can be helped. :-)

Here's the information requested by LonerT in previous posts:

Can you boot in Internet Recovery and run

diskutil repairDisk disk0

Feb 4, 2016 12:28 PM in response to Loner T

Ok, but I just checked and now it's Disk1. Should it move around like that? If so, how do I know what disk it will be in recovery?

A reboot can change the disk numbering. Run diskutil list in Recovery Console -> Utilities -> Terminal and pick the correct disk.

Ok, repaired bootcamp drive, anything else I should do before I leave Internet Recovery? It took 20 mins to load..

Feb 4, 2016 1:34 PM in response to Loner T

DUDE, YOU DA MAN!!!! This fixed it, booted directly into Windows 8, no intervention, then booted into OSX with no intervention! 🙂 😮

I just need to be sure the CD/DVD Drive works and I'm good to go!

Thanks Loner T! 🙂

Please backup OS X, Windows and create a Windows System Restore point.

Feb 5, 2016 6:37 AM in response to Loner T

Done!

One question, is there a way to safely install Ubuntu on a mac?

With Bootcamp already in place it is a pain. Can you install Ubuntu on an external disk?

Feb 5, 2016 11:48 AM in response to Loner T

Could install it on an external drive, then create an image on my network of that drive and then copy that image to the empty partition on the Mac?

1. You already have Kodibuntu. Is it KODI?

2. Your Bootcamp disk can be used to install Linux, since it has room for two more MBR entries, if required.

Feb 5, 2016 11:57 AM in response to Loner T

That's the partition I was going to install it in. It's called Kodibuntu, it's a very light version of Ubuntu with Kodi integrated into it. So I created that partition to instal the Kodibunto on to, it's what started this whole mess. I know I can put Kodi on the Mac or windows, but I was hoping I could do this and gain some performance from the MacMini.

Can you post the output of the following two commands for both disks?

sudo gpt -vv -r show /dev/diskN

sudo fdisk /dev/diskN

Pick the N values for each of the disks.

Can you post the output of

sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C

This is to see what is in KodiBuntu.
