Wanna try hackintosh!!

The idea of hackintosh really fascinates me I have tried hackintosh some years ago on my dell Inspiron 5520 (it kinda worked) it's a really old laptop but I still daily drive. So i again wanna get back to hackintosh on the same exact laptop (I still daily drive that laptop and it still works good) i have tried Catalina before on that laptop but I was noob at that time I did booted up to Catalina but when I unplugged the usb it didn't booted up (now I know why it happened) so now I wanna try big sur "maybe" I lowkey spent a whole day trying to use big sur I was able to make offline installer but it didn't worked it showed that " update can't be done on this ..... Blah blah" (I don't remember the exact line) the fix was to make an online installer and idk why I have only booted up in hackintosh only once (when I tried years ago) but now whenever I try something happens and it doesn't end up working which is frustrating. So maybe someone please guide me I know the basics like how to make EFI & how to get iso file for big sur etc etc but still in the end something breaks idk why and also maybe u can guide me which version of hackintosh is best for my laptop

Dell Inspiron 5520

I5 - 3rd gen

Intel 4000 (I know Intel 4000 is problematic for hackintosh)

8 gigs ram

HDD (I know hdd sucks)
