After Flashing Rom No Os Installed

[Septimua]

Recently I flashed xiaomi.eu's 6.11.10dev and 8.1.6.0 stable on Twrp 3.0.2-3 after wiping data, cache, dalvic and system. Flashing of these rom were successful but when I press reboot system it says No OS is installed swipe to reboot. I didn't reboot instead I flashed Cm13 ROM. However I want to flash one of these xiaomi.eu rom. So I want to know why its stating No os is Installed? Is there any solution to fix this. Regards.
