After installing Caldera 2.3, I thought, on reboot it failed with the message,"no operating system', In all I attempted 5 installations, varying the boot location, all failed with the same message. I was previously running Caldera 2.2, with no difficulties. A solution would be wonderfu. Regards, Frances Nicholson

I assume Lilo was installed as I was asked where I
wanted boot manager.

The whole hard drive is used by Linux no partitions.
except those made by Linux during installation

The machine would have held just 2.3,

try this:

dd if=/boot/vmlinuz of=/dev/fd0 ; rdev /dev/fd0 /dev/hda1

make sure there is a disk in the drive.
Make sure the BIOS is looking to boot from the hard disk.  Some of them wont find an operating system on the hard disk if the CD-ROM is checked first.

Where do I type the line, there is no    
command prompt, after memeory, bios ,etc, the no operating system pops up,
When I tried to use Partition Magic to create a dual Win98/Linux disk, I had similar boot problems, and decided I really didn't need to keep Windows, and used fdisk to delete both partitions.  I then installed 2.3 on an old machine and it works (kind of).  I  tried it on a newer machine with a new video card, and neither one would give me an decent resolution (video mode Linux calls it).  I've now joined several questions so that I can keep up to date.  Hope you don't mind.

boot from the cd

when lilo comes up asking for an image type this:
boot root=/dev/hda1

then, it will be just like you booted into your system from the hard drive.  Now you can make a boot disk so you can at least boot.

What are the parameters of your drive?
If you don't want windows at all, you can type this:

dd if=/boot/vmlinuz of=/dev/hda ; rdev /dev/hda /dev/hda1

that will install the boot image to the mbr.
