Computer was found to be full of viruses. Files have been deleted in error and can't connect to internet. Windows files are missing and programs will not run. I want to format the computer and re-install Windows. I have a Windows 98 CD and startup floppy and all the required drivers. I have managed to successfully re-format Windows XP but doesn't seem the same. Also when I changed the BIOS to boot from CD i got a fail message.
Make sure you have no peripherals connected before starting. Make floppy first boot device. Boot with startup disk in floppy drive and when asked accept 'with cd-rom support' when floppy finishes loading put cd in drive note the drive letter assigned and type D:\setup (where D is your drive letter) and away you go
