Also please add the -v (verbose flag) to the boot arguments,. If you not sure how, reference the Dortania Install Guide ,or I can upload one already done for you. That way you should get more information as to why it reboots.

It's definitely not that, I don't have XchiPortLimit turned on in the EFI folder you are using. I don't know what you mean by 11.2, regardless any version of Big Sur should work. As @UtterDisbelief mentioned your preexisting Windows/ Linux setup could be complicating what you are trying to do. Did you try the modified EFI folder I attached above so you can see where it reboots instead of only seeing the Apple logo?Is it because I was trying to install 11.5 and there's and "XhciPortLimit patch will result in unbootable machines" stuck in a boot loop ?

As mentioned here: XhciPortLimit broken in macOS 11.3 Beta 2(20E5186d) XhciPortLimit patch will result in unbootable machines, and so will need to find work arounds or new patches to resolve this s...
Should I try to install 10.15.7 or 11.2?
Sorry, uploading is taking forever this morning. Here's the modified EFI folder with verbose mode.
Any questions as to what or how to modify your boot files is better explained here (lots to read I know but great documentation and how some users create their own)
That drive should work, just make sure it doesn't have any other operating system on it first for simplicity's sake.
