Hi, I was wondering how to get bootloader to boot new kernel.

I have 4.9.16 installed and configured/compiled/installed 4.4.52.

after making & installing new kernel I ran
Code:
grub-mkconfig -o /boot/grub/grub.cfg

which output
Code:
Found linux image: /boot/vmlinuz-4.4.52-gentoo


/boot/grub/grub.cfg contents:
https://paste.pound-python.org/show/PTRk91CIa96L5kxUzceX/

after rebooting, grub only shows menu selection for 4.9.16

uname -r returns
Code:
4.9.16-gentoo


Thanks

/dev/sda2 was not mounted to /boot.

4.4.52 was installed on /dev/sda4 in /boot directory

mounted /dev/sda2 to /boot and reran the following:

Code:

cd /usr/src/linux
make modules_install
make install
grub-mkconfig -o /boot/grub/grub.cfg


it found both kernels

rebooted, menu entry for new kernel was there, & it boots just fine
