Unable to boot into an earlier kernel(SOLVED)
« on: November 12, 2019, 10:25:06 pm »
Hello Peppermint people, I'm having a problem booting into a different kernel, every time I select a different kernel to boot up, I get the message that I have to load the kernel first. This could be problematic if I really needed to boot a different kernel. How can I fix this?

Find which distro is controlling the bootloader and update grub in that.
