Check '/etc/lilo.conf' to make sure it indicates the proper partition for Linux and run '/sbin/lilo'. If you are unsure could you post the contents of '/etc/lilo.conf' and your partitioning scheme?

You need to install the newest version of lilo, or use grub instead.  If you install RH 7.2 you won't have this problem if you use the grub bootloader by default.

Edit /etc/lilo.conf

As the first line in it put:

Remove any line that reads:

Run "/sbin/lilo" as root.

As part of your distribution (RedHat CDs) you ought to have a copy of 'linuxconf'.

This tool is very good with all-purpose linux configuration (including lilo) which general users will find helpful.

P.S. Check whether you've installed lilo using 'rpm -qa | grep lilo'.

If worst comes to worst you may need to reinstall RedHat to avoid the 'cylinder exceeding' error (which is usually not a good sign to continue)...

I'm 99% certain that the version of lilo that comes with Red Hat doesn't have the 1024 problem, you just need to configure it to use LBA addressing, which is what the instructions I gave you above do.

You can find the home pages for lilo and grub by searching on but you shouldn't need to upgrade

I again i reinstalled redhat 7 in 20gb harddisk.Now lilo menu comes during booting time and i am able to go to windows also.
I partitioned 5gb for windows.
I installed redhat within 8gp partion(/=1.5gb,/boot=100mb and swap=100mb).
May be because of this it comes or not.

It is - you put it within the first 1024 cil, which means you don't need lba32 mode enabled.

It would have been quicker just to edit lilo.conf as I described though!
