[Solved] Boot\Install after mobo+cpu+ram upgrade

[BreBo]

This is what I get.
Thanks for your patience for helping me out !

"Still waiting for root device".
When installing this means that your USB flash drive cannot be found.
This is usually because the flash drive is in a USB3 port.
If this is the case move it to a USB2 port, if it is already in a USB2 port move it to another and try again.
Repeat until you have tried all USB ports.

I tried all my USB port (back and front) and results are the same.
I think that all my USB ports are USB3 (all are blue).

I happened to have a USB3 to USB2 motherboard adapter.
So I connected my front ports to the USB2 motherboard socket.
Now if I boot with verbose I have different text, and then my monitor suddenly goes to sleep.

Could be your HD 6850 needs a device id

I got it to work !
The issue was that inject ATI was always marked.
Once I unchecked it and spoofed the GPU and CPU ID as you said,
I managed to make a clean install of Sierra.
I'm currently restoring the os from my time machine backup.
I'll update if everything's working.

THANKS A LOT BreBo !!

Ok, stuck again..

I completed the installation.
After reboot I booted from the USB again and clicked "Boot Mac OS X from SSD",
And got this screen (image with Apple logo). This screen appears for 3 seconds
And after that the PC reboots. I booted with verbose and got what's seen in the second image.

I must say that I have to edit the GPU and CPU ID every time I reboot the PC,
Otherwise I'm stuck at the apple logo.

Any ideas ?

The problem appears to be with the FakeSMC plugins for HW monitor - Remove them.

How do I remove them ?

Ok, managed to install and boot Sierra successfully !
The solution was to make a clean installation without restoring from my time machine backup.

A few issues -
In order to boot Sierra I have to enter Clover settings on each startup
And spoof the GPU and CPU ID. It resets to 0x00000000 on each reboot.

At the first boot I had network but no audio. I used MultiBeast to install ALC887
And after reboot I still had no sound, and suddenly network also stopped working.

How to fix all this ?

 

[mgold85]

Bumping due to success with fixing ethernet.
Still having trouble fixing audio.
My motherboard is gigabyte GA-Z270-HD3P with a Realtek ALC887 codec.
I tried installing with MultiBeast but it still show no audio devices.
Any ideas ?
