You just had to reinstall that other operating system on your dual-boot box.
Now, mysteriously, you no longer receive that familiar Lilo:
prompt. All is not lost. You just need to re-install Lilo to the MBR (master
boot record) of your drive.
You must be 'root' to do the following.
- Boot Linux using your boot disk, a rescue disk or your installation
- Mount the / partition from the hard drive to your current directory
- Run /sbin/lilo -r <where you mounted />.
- umount <where you mounted /> (Notice that's not
- Boot linux.
- Your boot disk. Your distribution should have given you the
opportunity to create a boot disk during installation. It's time to test it.
You may have to alter the BIOS settings of your computer to change the boot
sequence to A:,C:,CDROM. Try just popping the boot disk into your A: drive
and restarting your computer. If it ignores the boot disk and reboots that
other operating system from the hard drive, change the BIOS settings.
- A rescue disk. You can create a rescue disk using, for example, Tom's Root/Boot. Instructions
for creating this are on the site. Other rescue disks may be obtained from
the system on a rescue disk is old compared to your installed system.
- Your installation CDROM. Again, you may have to adjust your BIOS
settings to allow the CDROM to boot. Almost all distributions allow you to
'jump' to a command line console before any actual installation takes place.
Usually, this is just after you select the language and keyboard to be used.
At that time you should be able to use Alt Ctrl Fn where
Fn is one of the function keys. This should get you to a command
prompt. Run mount to see if the Linux partition on your hard
drive is mounted yet. Run fdisk -l /dev/hda to see the names of
the partitions and their types, assuming you are using an IDE drive and your
Linux partition is on the first or only drive (/dev/hda).
- Mount your / partition from your hard drive.
- See what is already mounted: mount
- See what directories are available: ls /
- See the names and types of partitions: fdisk -l /dev/hda
- Mount your Linux / partition to your current directory tree:
mount -t ext2 <partition name> <directory to mount to>
NOTE: if you have a separate partition for /boot, this
must also be mounted. Example: if you mount your / partition to
/tmp you would need to mount your partition for /boot to /tmp/boot.
- Run /sbin/lilo -r <where you mounted />
That -r switch is important. Normally, your lilo.conf
configuration file is at /etc/lilo.conf. But if you mounted your /
partition at /tmp, for example, the full path is now /tmp/etc/lilo.conf.
The -r switch tells lilo to chroot (change root) to the
directory specified and seek its configuration file from there.
So, if you mounted your Linux partition to /tmp, then you would run
/sbin/lilo -r /tmp. If the system you booted (boot disk,
rescue disk, CDROM) does not have /sbin/lilo, you would run
/tmp/sbin/lilo -r /tmp instead.
- umount <where you mounted />
You should make sure you umount any of your hard drive partitions
that you have mounted. umount them in reverse order that you mounted
- Reboot. You should be able to issue shutdown -r now and
reboot. If you get a message such as "shutdown: command not found", try using
Alt Ctrl Del to reboot. If that fails, hit the reset switch.
The FreeBSD bootloader can be installed from a DOS prompt. If your partition
tables are not too weird, it will detect all bootable partitions and present
you with a simple, cryptic menu at boot. You select the partition to boot
using the function keys. It is available at
Download bootinst.exe and boot.bin then, from a true DOS prompt (restart in
DOS mode) run bootinst.exe boot.bin
When you reboot, you should see the FreeBSD bootloader's little menu. Be
quick to select or it will boot the one by the F1 label.
