Have you tried running the DVD in text mode ? Maybe it's just graphics issue.
Otherwise, you can install on another machine and add the elrepo kernel.

You think, do you install an operating system on another hardware?
Then insert the disk into this problém hardware?
Will there be a problem with some drivers, IRQ...?

If you install the disk on another hardware, and then return it to the problematic one - you must boot from the rescue stanza and rebuild the initramfs for the other kernels.
Once done, you should be able to boot the machine without a problem .

so it should be enough:
1. Boot SystemRescueCd
2. Then run for example: dracut -f /boot/initramfs-2.6.39-400.17.1.el6.x86_64.img 2.6.39-400.17.1.el6uek.x86_64

then restart and that's all?

If that is the kernel you have, it's not CentOS and it's based on EL6, not 7.

I know, I copied an example

I still wonder if you can integrate a newer kernel into ISO Centos DVD?
Has anyone tried it?
