MacBook Pro 2008 installation problem!

Hello everyone!!!

I’ve made today a bootable usb to install big sur on my old 2008 MacBook Pro (mountain lion os). I’ve made it using my other Hackintosh machine and it seems working. Although I’ve managed to boot from usb and start the process when I’m trying to pick the hdd to install big sur I get the following error : the base build is not compatible for this install method . Anyone has any idea of what is going wrong?

Thank you in advance!
