I just bought a used MacBook Pro from 2011 a1286 and trying to get it to boot but I tried reinstalling the Mac OS which is high serria but about half way through boot it just turns off and back on I went into verbose mode and this is what it came back with I’m not sure what could even be causing it going through the lines

Are you performing the installation by booting from a USB flash drive High Sierra installer properly made on a Mac?
Yes I made it on my MacBook Air using apples guide and it said it was done successfully
So I’ve looked it up but I don’t see any graphical issues or anything it just turns off and restarts over and over
RadeonGate can cause all sorts of difficulties because the discrete graphics no longer work properly.
The MPB 15" and 17" models also have "integrated" graphics built into the CPU that don't rely on the internal discrete graphics.
There's a long-running thread here on how to DISABLE the discrete graphics so the computer can continue to boot and run on the integrated graphics only (with some limitations):
Force 2011 MacBook Pro 8,2 with failed AMD GPU to ALWAYS use Intel integrated GPU (EFI variable fix)
You need to take time to "read up" about this.
I'm not saying it is your problem, but it could very well be.
There is no real hardware "fix" for RadeonGate other than to replace the defective hardware. And the replacement hardware (not sure if it's just a daughtercard or a complete motherboard) will eventually fail as did the original.
I see you "just bought this" as a used item.
It's regrettable that you've been "caught" by this, I'd put that on the seller for not informing you of the issue first.
This was a MAJOR problem and issue with the 2011 MBP 15" and 17" computers.
Will the seller take it back?
If not, hope you didn't pay much for it. (sigh)

It’s very weird but I installed the Mac OS on another MacBook Air I had then moved the hard drive back into the pro but it still crashed halfway through boot and restarts so I thought let’s try to boot into the recovery part of the hard drive that made it in successfully so I reinstalled Mac OS through the OS X utilities and it worked I’m in Mac the only weird this is a search this serial number up to find the exact model and when searching the serial number on the case I get a late 2011 MacBook Pro but now that it’s on it says in my Mac info that it’s an early 2010 so I feel like someone has changed the board in this already with and now older version of the board this whole MacBook is a mess and I should of bought it but I only paid $50 for it so not too bad
Now I’m even more confused after i booted into Mac OS now it won’t boot restarting its doing the same thing again any ideas
