I am trying an dual boot. I tried using the methods of around 5-6 yt tutorials. This what is the result. I checked the efi and everything multiple times. I want to boot Tahoe

Once, i managed to get into macOS, but unfortonaly i didnt get the internet to work so i had to stop it. I cant boot in and if i press boot the infinte computer self repair thing comes up.

If i wait it gets timeouted and the self repair jumpscares me.

I cant normally reach the bios i have to open windows and do the shift restart thing. I also cant open the Boot menu i tried everything.

I have a Dell Computer

Please i need help i am working around 10h on this i cant get it to work.
