Can live boot into linux but not win or opencore, no bios too

Hi guys, i got catalina working on my os but forgot to add boot data(efi) after install. I have tried many times to install it but today i was able to see opencore menu but there was no macos installer. I have created the usb multiple times based on dortania guide but to no luck. I tried installing windows but its not loading the win install usb. Meanwhile im able to install ubuntu into the drive and boot from it. Also, i cannot get into bios menu. What the heck is going on? Edit: Im starting to thing there is something wrong with the usb, can that be possible? Since linux works fine. Thank you
