How to boot Knoppix from existing HD image rather than CD?

Hi all!

First of all, I am brand-new to Linux, so please be patient with my stupid questions. :?

Some time ago I installed Knoppix (in Debian mode) on my old DELL Inspirion 7000 laptop. Now I'm trying to replace the old install with a newer version of Knoppix in Knoppix mode. I have created a disk image that I'd like to use automatically at boot time. However, it seems that I cannot boot into the newer HD image without the Knoppix CD in the CD-ROM drive! With the CD in the drive I am prompted to choose to boot up using the HD image or the one on the CD. Without the CD, however, the laptop boots directly into the old Knoppix/Debian install.

What am I doing wrong? How do I replace the original install with the new one?

Please spell out what to do step by step because I am still figuring out my way around Linux and am still weak in terminology. Thanks to everybody in advance!

Do you use lilo or grub boot loader?

In case you use lilo, you should adjust an entry in /etc/lilo.conf to include your new image.

See man lilo(8), lilo.conf(5) for more.

With grub, add an entry in /boot/grub/menu.lst

Hope this helps you a step towards the way out.

I'll give it a try. Thanks for your response.
