Axios Thanks, this is helpful though I had set it up similar to this just with the Apple disk conventions. Will take another boo at it this weekend when I get some time. By altering the bootmanager settings I've definitely caused further install mischief on my machine. =p

Turn off the machine when you try this turn it back on as its coming on hit f9 every 1/2 second or so see if that does anything!

In order to maintain compatibility with MS-Windows, Apple uses a hybrid UEFI and Legacy MBR mode. Apparently, there is an NVRAM value that tells the firmware whether to attempt to boot in UEFI mode (OS-X) or in legacy MBR mode (Windows). That value is controlled by your selection in "System Preferences > Startup Disk". (Don't ask me why, ask Apple)
I think I would seriously try the legacy solus to see if it boots. if it does would tell you theirs a problem with the efi setup

Am done rambling let us know how it turns out this is what happens when your a tech for 30 years..haha

    Justin And yet, it's the only thiong that is working. I think it's grub2 actually.

    Axios Hehe. I hear you. I have about 25. I ended up bricking the machine and then completely nuking the partitions and boot manager and starting from scratch. Solus would not install despite best attempts. I am stumped as to why at this point but I was capable of getting POP_OS! 19.10 to install (I needed to disable encrypted drive as the keyboard was not supported when booted in but after that works fine.).

    I will do some digging around some more when I have more time to play with it, but I may wait for Solus to update to 4.2 =p and see how POP_OS does when it gets to the 20.04 release since it's Ubuntu and Debian based. The latest Ubuntu 20.04 nightly borked on installing (despite a previous working) so feel like maybe some patience here might be a good idea. Lol.

    I think the biggest issue here for me is not really understanding what precisely is going wrong. I will go read up a bit more about EFI nad new bootloaders and what mystic things Apple is doing differently. LIke I said, I love the hardware of the Macbook 12" 2016 but at this point, probably looking at a new LG Gram 14" when they're out in a month or so to just make life easier on myself. =]

    That makes 2 of us I read somewhere One needed to use apples diskutil to setup partions because they did things different could do a internet recovery and use the diskutil and see if things fair better just a thought. Also I saw one guy said keep the apple boot part because it needed because way apple does things. It seems there is no one way on apples to get them working sometimes. Trial and error I guess
