Recovery mode not loading on MacBook (Late 2008)
There are a couple of options, the first would be to buy a new copy of macOS 10.6 Snow Leopard from Apple: https://www.apple.com/uk/shop/product/MC573Z/A/mac-os-x-106-snow-leopard

Alternatively you can use this Mac or another to download a copy of Mavricks via the App Store, which can be used to create a USB bootable macOS Installer, there are instructions here as they are quite long: https://www.macworld.com/article/2056561/how-to-make-a-bootable-mavericks-install-drive.html

The main consideration however is that if you never downloaded macOS Mavericks on your App Store account you will not be able to download it in order to create the bootable USB, and will need to ask around friends.
