Thanks. I’ll try it.

Thank you for replying,, now it works. But I have to change bios settings every time I boot windows or macOS because SATA Operation is set to RAID On but macOS is set to AHCI. Is there other way to to solve this??

I’m trying to install macOS Catalina on dell latitude e5550 the first time but I know little about computers and Hackintosh. My computer boot at first time but when I choose hard disk to install it reboot but i can’t boot to Mac just boot to windows and I no longer boot from usb anymore. Can you guide me, please?? Sorry for bad English.
