Hello Again,
Yes it was booting but crashing before displaying the GUI Install of MacOS and i found the root cause of the issue.
In fact, i guess in models with 2 GPUs (Intel+Nvidia), The patch for the intel GPU is different,
As an attempt, i tried to use GPU patching from various other Lenovo Models and apply to my laptop. Hopefully ! The IdeaPad S145 GPU Patch worked for me !
So, in my config.plist, i replaced :
