Adding configuration to GRUB2

Hi, ALL,
Is it possible to add the configuration with the newly compiled kernel to GRUB2 existing configuration?

Its interface is completely changed and I'm now completely lost...

Thank you.

Are you looking for grub2-mkconfig -o /boot/grub/grub.cfg?

charles17,
If I have

vmlinuz-x.x.x
vmlinuz-y.y.y

Does it generate 2 lines for me to select on reboot? Because I'm looking for 2 entries in the grub menu to select to boot to.

Thank you.

It creates boot entries for all kernels found in /boot

charles17,
Apparently it didn't I ran this command and when I rebooted, I saw only one line to select for the gub.
When I checked, it is the latest kernel - no old kernel configuration was present to select.

Luckily the new kernel booted successfully and I can now remove the old configuration...

Thank you.
