Please help and I will drop a thanks on the solution that works.
extract the boot.img from YOUR_CUSTOM_ROM.zip and extract it to the location where fastboot is located
turn off your phone, reboot into bootloader (VOldown+Power)
connect phone to PC
cd into fastboot directory via cmd
type this: fastboot flash boot boot.img
and then reboot your phone .
