[SOLVED]add a custom initramfs img to grub

I read through the Improving Boot Performance wiki, and as it suggested, I tried creating a more slimmed down initramfs image using mkinicpio. So now in my /boot folder I have two images - initramfs-linux.img and initramfs-linux-tiny.img. My question is how do I boot using the new image? I tried running grub-mkconfig, but it only sees the first one. Is there another step that I am missing? The blog linked to by the wiki mentions adding it to the bootloader, but doesn't offer any specific information. The wiki entry for mkinitcpio only mentions that you need to add the img to the bootloaders config file, but isn't specific either. Any help is appreciated!

Do you have os-prober installed?

Edit: I'm not quite familiar with using different initramfs images for the same kernel, so I'm not completely confident that would help. I misread and thought it was for two different kernels.

SolarBoyMatt, I installed os-prober, ran it, ran grub-mkconfig again but my custom img is still not being seen. I'm reading that now, Trilby.

So I just changed the image at the command line during boot, and I couldn't really tell a difference in boot times. I'll just mark this as solved.
