My son has been given my old ME computer.
I don't know what he has done to it but, now when he tries to boot up, he
gets the message "Invalid System Disk, replace disk and press any key".
He tell me that he has done nothing to it except download AVG update (Took 3
hours!!!) and uninstalled a printer.
Anybody any ideas please.

Confirm that a Floppy Disk hasn't been left in the A: drive. If so, remove
it and 'press any key'

If there is no floppy disk in the drive, he may have corrupted one or more
critical boot files.
You will need a Windows ME boot disk. If you don't have one go to
www.bootdisk.com to get a file that will make one.
Boot from this boot disk (sometimes called Startup Disk) and at the prompt
type the following
sys c:
Then press enter and it should say 3 files copied.
Then remove the boot disk and restart.

Hi and thankyou for the quick response
There is no floppy in the drive. I thought I would try to enter safe mode
and then go for system restore, but cannot get into Safe Mode.
I have downloaded the boot disk as suggested and will give this to me son
later today. Fingers crossed it works.

The invalid disk problem for ME can be caused simply if certain attributes
for the DOS system files have changed. Check that both copies (to avoid
confusion) of command.com are system but not hidden, read-only doesn't
matter. IO.SYS should be system and read-only, hidden doesn't matter.
MSDOS.SYS should be read-only, system, and hidden. If you have a patched
system and are using working Config.sys and Autoexec.bat files like I do,
these two files should have normal attributes. I hope this helps - Good
Luck.
