MacBook Pro Late 2011

-greetings to all fans of the mac world...
-i thank the helpers who will want to support me...

-i have 2 macbook pro 15" 2011 late.
-the first mounts high sierra with TIRESIAS 2 hardware modification and works great ...

-the second always worked with high sierra but only with the usual software modification...
-my problem started when i tried to install windows 10 in dual boot (without boot camp)...
-I couldn't install it, it crashed at the end of the process with a blue screen...
-then i tried to reset everything but the mac went into fault...
-in a panic I removed the ssd and hdd and initialized them ...
-I turned on the mac with the alt+r keys to enter recovery but a folder with a folder ? mark appears ...
-then I made a copy of the ssd (mac 1) with carbon copy cloner and inserted it into mac 2 without result, always folder ? mark...
-If I start the SSD from the usb port, it is read, you see the apple and the progress bar which, however, stops at 3/4 with a white screen...
-I tried all the possible resets and also to enter the bios to remove the AMD GPU again via software but it is impossible ...
-I also removed the R8911 resistor according to indications but the screen went black...
-then I put the resistor back on and the screen came back to light...
-I also tried to install high sierra from usb installer, but after apple bar stuck and blue screen...
-I'm looking for help to get it up and running again...
