How restore lilo after install windows

Good afternoon bloggers, i have some tutorial but don't familiar to hearing
if you dualboot Slackware with windows and reinstall windows automatically lilo nothing on Slackware, but now restore like originally :)
okay, before restore lilo you must have 3:

1. USB Flashdisk min. 4GB
2. software booting or commonly called unetbootin, usb creator etc. #recommend use unetbootin
3. iso slackware operating system

and then create boot live slackware dvd on usb flashdisk with unetbootin, after create;

1. login with root on slackware
2. check your partition with fdisk -l or cfdisk whatever you want :) #there my partition slackware on partition /dev/sda3 so adjust to your partiotion
3. and mount # mount /dev/sda3 /mnt
4. # mount -o bind /dev /mnt/dev
6. # mount -t proc none /mnt/proc
7. # chroot /mnt
8. # /sbin/lilo 9. # reboot

now see your lilo has restored, CMIIW.
