Hi, I am predominately computer illiterate here so I will need some very detailed help.

I work with the mentally and developementally challenged. We had a computer donated to our individuals with no origional software. We were given a Compaq Deskpro EN series 6350/6.4 DOM computer. When turned on I am receiving the following message:

Invalid system disk
Replace the disk, and then press any key

There is no disk inserted, why is it reading that there is a disk when there is not? I would if I can get past this error also like to reformatt the harddrive but again have no origional disks. How can I do that one

Any help would be deeply appreciated by me and my individuals! Thank you.

First off make sure that there is not a floppy disk in the floppy drive.

Just to clarify: You received no Recovery Disk for the Operating System?

This is one possibility taken from this troubleshooting guide:
