slaughtered by the internet within 20mins.
Insert the reformatting CD before your computer starts up, or
insert before you restart.
Make sure your system boots from the CD Drive before it boots from
the hard disk. To change bootup order, go to BIOS settings. Press a
button when it starts up, usually shown on screen which button

When you start up with the CD inside your drive, There will be
words instead of the Windows Loading screen. If it shows up Windows
98, it is actually reading the CD rom.
Next will be a low resolution menu asking what you want to do.
Reformat your computer will be one of them.
Click on it and it'll ask whether you want to partition the
harddisk or leave it as it is.
Then after that it'll run by itself. If theres a few CDs
altogether, you need to change the disc when it tells you to. If
your running from DVD, you can let it run while you go watch your
favourite television programme.

settings and registering your copy of Windows. Skip it. And make
sure your internet is disconnected until you install security
programs like anti virus and firewall

all activated.
