WIN98se: "Invalid System Disk" on Reboot

Avast Free Antivirus / Premium Security
1

I downloaded Avast! 4 Home for my sisters computer that has win 98se on it and set up the AntiVirus protection to “schedule a boot-time scan” so when I rebooted it I got a black screen with the words: “Invalid System Disk”.

So I changed the boot settings in BIOS to boot 1. cd 2. hd 3. floppy and rebooted. Same “Invalid System Disk”

So I made a boot cd (my computer doesn’t have a floppy drive) for WIN98se put in in her computers cd drive and the screen went away but its just black and has a flashing “_” on the top left corner of the screen and nothing happens when I press the keyboard. I made a boot cd for WIN98 and got the same problem. :o

The boot-time scan is not supported on Win9x platform - such an option is simply not there… ???

Her computer started fine before I installed the antivirus software and now it won’t start.

So even booting from a bootable cd fails, right?
Than it has nothing to with Avast, but more likely the hardware.

  • Open the system
  • unplug all cables
  • take out the ram
  • put back in the ram
  • hookup the cables
  • try to boot (make sure the drive is rcognized correctly in the bios)

And while you have the system open, perhaps do some dust cleaning also.
