What causes the error message

When I start the computer, I get a blank screen with the following message:

"INVALID DISK SYSTEM"

I already inserted all floppy disk that I have and keeps giving me the same message.

There is any way I can get rid of that message?

It could be either of (2) things:

1 A boot sector virus: If so, run a current version of antivirus software and see if that doesn't

correct it.

2 Io.sys could be missing or corrupted: If so you neee retor the file from a backup or emergency startup disk;

Do the following:

A Boot from the startup disk

B Run the SYS C: command to restore the Io.sys, Msdos.sys, Drvspace.bin and Command.com

C Remove disk and reboot
