installed & configured new kernel, but system still sees old one

1. Help to boot new kernel with grub -delited the old kernel before tried the new one

Can someone help, how to update Grub so I can boot into linux. I
updated the kernel with up2date software on RedHat and followed the
Instructions to delete the old kernel files from /boot and now I can't
boot into anything old or new kernel. What do I do to boot into linux.
And Grub boot loader doesn't let me run any usefull commands. Thank
you. I tried to update Redhat 7.3 so it would let me boot into linux
but that didn't work. Thank you.
