No operating system found after install UEFI?

I'm trying to install debian and when the installer starts it UEFI at the top, install completes however on reboot it says 'no operating system found' but I have tried different bios options but to no avail.

Hi linuxczar,

First of all, you need to disable both CSM and Quick Boot and also make sure Secure Boot is disabled.

Secondly, during the installation where did you direct the bootloader to?
It usually asks for a destination drive
