The only option is to create a startup disc, format again, and then place the Windows 98 Cd in and install again using a bootdisc.
Find bootdiscs here:
You'll need to unzip these files, and then place them onto a blank formatted floppy disc (right click the floppy drive, and go to format, and follow the steps). Now place the files from the zip file onto the floppy disk.
Unzipper = Winrar - Use this to unzip the files if you don't already have winzip:
Now restart and place the Windows 98 disc in, with the bootdisc in as well. It should now boot and you should be able to start the setup by typing this:
x being the cd rom drive
I hope this helps, and works...I just hope the Windows 98 boot up disc would work when running from a Windows ME and Windows XP one it seems...
If it doesn't boot, try downloading the Windows XP boot disc from there and doing the same thing
I really hope this works
