Dual boot, new Sierra OSX working, old El Capitan system does not

[djdirect]

Hi friends

I am losing my mind over this, so I have decided to seek help amongst you guys. I apologize in advance for my lack of knowledge

So here is the thing, my old build was running El Capitan supersmooth, but when the system was to old to upgrade to the newest version of Logic pro and Sierra, I decided to make a new build from a Lenovo Thinkcentre, with the following specs:

- I5 2400 3,1 GHZ
- 16 ddr3 RAM
- Nvidia 1050
- custom Lenovo Mobo (https://www.cnet.com/products/lenov...re-i5-2400-3-1-ghz-4-gb-500-gb-sela9ge/specs/)

So I installed Sierra on a new SSD, and after a few days of tweaking everything was working like a charm. But on my old system I had a lot of Logic Projects that I need, so at first I tried importing them, but a lot of files was missing, and a lot of plugins was missing as well. So now i am trying to boot up my old SSD with El Capitan on my new rig. The first time i tried, it actually booted up, but with a few graphical glitches, and it didnt recognise my GPU. But when I saw my old system on my new rig I was thrilled

But when I booted up the second time it was stuck at the apple logo, and then it reboots. I tried in safe mode and without "reebot after kernel panic"- flags, and i get the dreaded CPU 0 caller 0xfff fail.

So since I am terribly afraid of doing anything that would compromise my system and my old hdd, I thought I would ask the experts. Is this even possible, and do you have any advice?

If this works I would be truly grateful, and I swear I will dedicate my life into making the world a better place

Best regards
Kristian

You tried Migration Assistant(a program in Programs/Utilities) to get your stuff over to your new system?
Just copying a bunch of files is not going to work.

Yes I tried migration assistant, but my old ssd is 500 gigs (and almost full) and the new i only 250.

I tried making a clone of the El Capitan (to an external device), then deleting the ssd, then cloning my new Sierra system, then migrating my El Capitan to my newnew ssd, but then i get the the same problem. I tried only copying the applications, and only the files, but then all of the logic files was missing plugins and audi files. I think this is because of my new Sierra 250 gigs partion has a new useraccount (perhaps?)

A lot of the files you are missing are probably installed to the Library folders, /Library or ~/Library and the installations may be specific to the machine you installed to (authorisations, licenses etc). Unless you know where everything is in the filesystem, you should copy your documents/data to your home folder and re-install the software on the new machine. Keep your old disk handy in case you need to search out specific configurations, patches and other items as you go on.

Exactly This is the reason I am wishing there is a possibility to dual boot. If I could boot up my old system, AND update to Sierra it would be magic

You might start by disconnecting your sierra drive, and trying booting el capitan with a suitable unibeast stick (try safeboot).

aaahaaaaaa, so its possible to.... yes offcourse.... Man I am stupid.... Ok, so I will give my old system a go with a suitible unibeast stick, boot it up, update to Sierra (wich have native drivers for my GPU), and voila a system that matches my current, and the latest version of OS... Thnx a lot Vulgo, I have been looking down the wrong rabbit hole

If it boots, i'd uninstall any third party kexts before updating.
