Tips for installing Big Sur .

First of all,you need to have a working nvram

A working nvram is required  to install macOS Big Sur. The installer will write nvram variables during installation process, maybe macOS Catalina isn't required. So when you have a broken nvram it will keep restarting in second stage installation.Fix up nvram or use a emulated nvram.

On some Boards nvram isn't enabled by default.You need to go to advanced ---> RAM disk configuration add a raw ramdisk file(AMI bios). So don't forget to check it out .
