Anyone has a quad boot tutorial with OCLP?

Hi. I used to triple boot Snow Leopard, Windows 7 and Ubuntu 24.04 on my MacBook 6,1 but for some reason my Windows 7 install broke (it wouldn’t boot anymore). I tried booting a W7 install usb and the retail DVD but they refused to repair my install (they didn’t give me a reason but I guess it had something to do with GPT partitionning). As I didn’t have any important data on the SSD I wiped it and tried to start over trying a quad boot instead, adding Sequoia into the mix but I’m trying to boot the OCLP install USB I flashed from my hackintosh. It does boot but it will spit an error every time it’s in the first step of the install process. The only OS I don’t really care about in there is Windows 7 as I already have a very old desktop PC triple booting Windows 7 and 10 as well as Ubuntu 24.04. Does anyone have a tutorial for achieving this with or without Windows 7?

Thanks in advance.
