Fixing MBR with lilo with a non-boot drive
I'm trying to update the kernel on a hard drive with Linux installed on it. Let's call this HDD1. HDD1 doesn't allow me to boot up normally, so there's no way I can get a shell on it and apply lilo as a boot drive.
I have another Linux installation which I boot from. Let's call this HDD2. I then connect HDD1 to the system that is booted up to HDD2. HDD2 is detected as /dev/sda and HDD1 is detected as /dev/sdb.
I then mount HDD1 on some directory, say /fix, as follows:
mount /dev/sdb1 /fix
How can I apply lilo and write to the boot sector of HDD1 instead of HDD2? Is it the following?
chroot /fix/ /sbin/lilo -v -v

It has been some time since I worked with lilo. Here is what I would try;
download and burn either fedora or centos cd 1
boot into rescue mode and let it mount the drive of the system
run '/mnt/sbin/lilo -C /mnt/etc/lilo.conf' (I believe this is where it is mounted. Please check after boot)
That should install lilo on the MBR of the drive you have configured in lilo.conf.
