Why? You could have just deleted the applications that were causing the hard drive to become cluttered. But even if you didn't do that, you should always have a bootable backup of your entire system, just in case the worst thing possible happens (and you know it will, at the worst possible time).
In any case, you should refer to this Apple Support document: http://support.apple.com/kb/HT1585
Your iMac DV SE 400MHz model originally came with a model-specific version of OS 9.0.4.
Some users have reported that after updating the firmware on their older Macs, the original install disk for OS 9 did not work. This apparently applies to machines whose original OS was OS 9.0.4 or earlier. The firmware update was to prep the machine for the installation of OS X.
If your CD for OS 9.2 is marked as an "Update" disk, it is not bootable even though it may have a gold 9 on white backgraound.
You will probably need to use a retail OS 9.1 or 9.2.1 Install CD; these have the gold 9 and white background, and do not mention "Update" nor any machine model on the label.
Is running OS 9 apps in classic mode while booted into OS X an option? If so, copy the System Folder from another Mac that has OS 9.1 (or better with 9.2.1 or 9.2.2) installed. A USB thumb dive works great for this. Transfer the folder to your Mac. It won't interfere with your OS X system which is in a folder titled System.
The Mac OS9 cd (white cd) I have is actually for version 9.1 and does not say update on it.
I have tried to boot my machine from this cd too but it doesn't want to know.
However, in OSX, when I have the cd in the machine, it allows Classic to be launched from the cd
but it does not allow me to install it.
I also tried with a retail version of OS9.0.4 but the result is the same.
How about if I dragged and copied the files on to the HD from the cds as Texas Man partly suggested?
Could anyone advise me specifically step by step what files and where to drag them if this is viable?
Didn't these machine come with restore disks?. They were a separate set. I have 4 for my iMac G3 600. Try installing them.
Try copying the System Folder to the root of your harddrive. Ex: Macintash HD
I believe System Folder is what is booted when cd boots. Copying will not do a comlee install something will be msissing. Don't know details. Should be enough to run classic apps if they run when you have the cd in the drive. Might try upgrading your classic. Maybe updates will fix. Apply Mac OS 9 updates.
Thanks Kurt. Yes, in hindsight I should have done what you said. However, at the time I just thought it was easier and quicker just to do a clean install. But I read the stuff on the link you sent, thanks, and tried a few things out. So far no luck but I will see what else is on that webpage that I can try.
Here's some good news. I've been able to see the OS9 CD icon on the screen after booting up with 'alt' held down when I attach an external CD drive via USB. However, my mouse and keyboard are unable to control the cursor or swap between icons and the onscreen arrows. The only key that works is 'Enter' which automatically leads to a reboot in OSX which is the only icon hightlighted on screen. So... it goes on... but I feel I'm making progress, albeit slowly.
I do not believe it is possible to boot a DV SE from an external USB-connected drive, but have you tried all other keys to select the boot volume? Likely candidates would be the first letter of the volume name, the Tab key... etc.
On the other hand I am certain you can boot the DV SE from an external Firewire drive. Get your hands on one of them and you might be all set.
It should boot from the internal CD/DVD-ROM drive if you hold the c key while it boots, though that ability might have been lost if the original optical drive was replaced.

I vaguely recall this and I believe it is correct. I am fairly certain it is impossible to downgrade the firmware. But it ought to be possible to boot into OS 9, since I did that on occasion. This was after upgrading the original HD to a much bigger one.
3DMonkey I have this identical model iMac with all its original CDs in storage. I may also have an OS 9 retail install CD, but am not certain of that. I could investigate this further, but it might be a while
RC, as I mentioned already, the keyboard and mouse is disabled after an 'alt' boot up.
Odd. Keyboard & mouse work for me with 'alt'.
You have wired usb mouse & keyboard? Original apple keyboard? Generic mouse works for me need to be connected directly to mac. No hub.
Could there be a poweron password? I think you would have to enter a password everytime. Could try remoing the battery for an hour or overnight.
