Sometimes you forget to do lilo after updating a kernel. In this manual we're going to recover the system!
Alright, you will need a Slackware (can be other, not very necessarily) LiveDVD.
Firstly we're going to mount our disk. If your system locates on only one partition, mount that:
mount /dev/sda1 /mnt
If on many:
mount /dev/sdaX /mnt #X - your root partition mount /dev/sdaZ /mnt/boot #Z - your boot partition
Mount /proc, /sys and /dev is recommended, sometimes necessary.
mount -t proc /proc /mnt/proc mount --rbind /sys /mnt/sys mount --rbind /dev /mnt/dev
If you don't already have a working kernel, you'll have to load it from slackware repositories.
# For Slackware64-14.2 dhcpcd eth0 cd /mnt/tmp curl -O http://mirrors.slackware.com/slackware/slackware64-14.2/slackware64/a/kernel-generic-4.4.14-x86_64-1.txz curl -O http://mirrors.slackware.com/slackware/slackware64-14.2/slackware64/a/kernel-modules-4.4.14-x86_64-1.txz
ROOT=/mnt removepkg kernel-generic kernel-modules ROOT=/mnt installpkg kernel-generic-4.4.14-x86_64-1.txz kernel-modules-4.4.14-x86_64-1.txz
After chroot we're going to do lilo .
chroot /mnt # I also recommend you to check lilo configuration lilo
If you need some kernel modules for loading the system, you can also setup initrd.
mkinitrd -c -k 4.4.14 -m ext4 -f ext4 -r /dev/sdbX nano /etc/lilo.conf # Configure initrd lilo
We've done! You can exit and reboot to the system!
exit reboot
