How do I find my grub kernel?
Booting From grub> The second line tells GRUB the location of the kernel you want to use. Start typing /boot/vmli , and then use tab-completion to fill in the rest. Type root=/dev/sdX to set the location of the root filesystem. Yes, this seems redundant, but if you leave this out you’ll get a kernel panic.

How to create vmlinuz and initrd in Linux?
I’ve found https://wiki.alpinelinux.org/wiki/How_to_make_a_custom_ISO_image that describes how to create ISO image but as I understand ISO and vmlinuz are different things. I had moby initrd and vmlinuz. vmlinuz is a kernel to load. No need to modify it for vm initrd is what I needed.
What’s the difference between Moby initrd and vmlinuz?
I had moby initrd and vmlinuz. vmlinuz is a kernel to load. No need to modify it for vm initrd is what I needed. So we will have access to the filesystem that will be loaded after the kernel.
Which is ISO file, vmlinuz and initrd.gz?
THAT is the directory you have to write in your grub.cfg after (hd0,0) (By the way, it should be loop, not (hd0,0)) substituting centos-7.1 I would also check its config scripts to see if some options are needed and add those options. The CentOS wiki has a guide to installing from USB that covers 6.5 and later (including 7.x).
Where can I find the internal kernel version?
Given the boot image, you could find internal kernel version string with file command: On most installations, you specify the root device to the bootloader. The root device is passed to the kernel as a parameter called root.
