  1. Hi! I had trouble upgrading windows 98 se to windows 2000 Professional so I went to DOS and did the C:\format C:

    Now, I get the following error message when trying to reboot: "Invalid system disk - replace disk and then press any key." I get this message even with nothing in any of the drives. Please tell me how to overcome this obstacle and successfully install windows 2000. Thanks!

    try booting from a win 98 recovery disk,

    C:\>fdisk /mbr

    else simply run fdisk from the floppy, create a partition then try formatting it.

    of course, this may not be necessary at all thinking about it.

    If you can boot with a win98 startupdisk, and create and format a partion, from a: type "sys c:" which will make your hard drive bootable to dos (It would the be a valid system disk, in evry sense of the term)

    Anyways, once you've got that far you should be well on the road to being able to install. Hope this is enough and that it's nothing more complicated. post back and tell us if it works or not.
